    Yeah, I saw he was on the Rival S out there. Nice job Trevor!

    Thanks guys. Sorry if this is a bit of a ramble and likely a bit TMI too. I got food poisoning Saturday night and was up from about 1:00 until Sunday morning runs sick from both ends until nothing was coming out. I sipped water on Sunday trying not to get dehydrated but at the same time making sure I didn't make a mess in my car. My work assignment was also gate and the facilities where across a live course. I was borderline from withdrawing at the Super Challenge for safety reasons and started seeing double on the way home at one point and had to pull over and rest. I have been intending to drop a summary here but this has been the worst sickness I have had in a long, long time.


    It was an awesome event and courses though! Huge thanks to the National staff and local region! The courses were fast going out and more technical coming back. The Blytheville Tour is the event where I was starting to see cords on the Hoosiers after 10 runs. I am happy to say that I have about 25 on the Rival S and don't see any cords yet.


    Sam, Bart and I had made a gentlemen’s agreement to use the Rival S at Pro’s due to the contingency. Where the Rival S seemed to be lacking some longitudinal grip in Milwaukee, they seemed much better on the Blytheville concrete. Ambient temp differences between Milwaukee and Blytheville likely played a part in that feeling. Managed to dip into the 2.1 60 ft's twice. The tires definitely need a bit of heat in them. Getting the timing right on both throttle and braking inputs has the car feeling more balanced. I was running front shocks 1/8 off full soft and rear on 1/8 off full stiff. Tire targeted hot pressures in the mid 30's front and rear.


    In practice, my first few lights started in the .700 range. I played with timing on the tree and managed to cut a .500 light. I then had a .507 and .518 and felt really comfortable with the tree.


    For Saturday my plan was to run .700 lights to leave a little sand on the tree though I did try to squeeze a quicker one in to see how much the surface changing had affected the light timing and red lit. I knew from how long I was on the limiter in 2nd that it would be faster going to third but not likely as consistent. I decided with the times I was able to produce in the morning that I would keep it to 2nd only in the afternoon as well seeing how much the other competitors might close the gap.


    Going into Sunday with a 2.59 second margin, I focused on the tree trying to get a feel for cutting closer to .500 lights. I was very happy considering no sleep and dehydration. Only three of the four were listed but I am pretty sure they were all .5xx with .574 as my worst and a .534 listed as my best. I kept it in 2nd for my first three runs focusing on consistency for the Challenge and then tried third on my last run as I had wanted a bit faster time on the right and also had hoped to stay ahead of Ron Williams on pax. I didn’t realized I coned that last run but clean it would have been my fastest. As it was, I ended up .018 behind Ron on index. If I would have been in a bump class with him, I definitely would have been going to third. Sam closed the gap to 2.49 but Bart still had his runs as second driver. Bart has done well in the past in RTF placing 2nd at Nationals so I knew that he could close the gap in a hurry. He did cut it in half down to 1.2 seconds.


    I qualified fourth for the Super Challenge. I made it through the first round of the Challenge and then faced Harvey. I didn’t want to leave any time on the tree and ended up red lighting by 5 hundredths.


    I didn’t do any tire testing. I did get some direct feedback from someone who did test both the Rival S and the BFG on the practice course. They said for them that the Bridgestone was a couple tenths quicker on the 20 second course. Ricky Crow in STR I had heard also switched tires. Not sure what he was on Saturday but he picked up significant time switching to the Bridgestones on Sunday morning.

  5. Well done and hope you're recovered from the Food Poisioning. Been there, done that, rough way to lose 10 lbs :)

    FWIW, this corresponds pretty closely to what we were seeing at Crows (very abrasive concrete, temps in the 70s) for the Pro TnT (my car on BFGs, other cars on Bridgestones, with several of us driving cars on each during the TnT) as well as to what I saw at my initial TnT on the car at Marina (less abrasive concrete, both tires on my car). As a result, we ran the Bridgestones for the Pro.

    I'll give the Rival S some more tries, including this Sunday at a local event back at Marina. I suspect lower pressures are key on them, then be careful to NOT go outside the tire's envelope since recovery doesn't appear to be as good as the RE71R.

    FWIW, Ricky Crow went from Hankooks to RE71Rs.

    Tough course at the Pro for the Fiesta and the front bar didn't seem to help. I think it may have hurt a bit. Lots of hard offset gates and a tight turn before the finish (I heard lots of references to it being a "pin turn") wheel spin seemed considerably more than Blytheville. I asked Sam if his car had more wheel spin than Blytheville and he said it seemed the same. We were both on Rivals. I have now seen cords on a set of Rival S tires that had only seen about 24 Pro type runs, 20 of which were on concrete on a cambered challenge car. Pressures being used were in the 35's. I believe the tires will need to be run at higher pressures. The tire didn't just cord though it actually somewhat chunk'd away. There was 1 to 2/32n'ds in the areas and the chunks were a quarter inch to a half inch and looked like they were between the outer tread block areas. I am not seeing the same thing on my tires yet with similar runs but the outside edges are pretty beat. I tried lower pressures and the car was rolling over badly on the sidewall to the point you could feel the front hopping. One person noted that the tire looked "deformed" under load. I know that person said they are planning to contact BFG. It could be something in the first batch of tires and not typical of the ones coming in the next release. I think pressures in the 38 or possibly 40 range are going to be needed which is what I have been running the Bridgestones at.

    On Friday, I ran the BFG's both morning and afternoon. The morning, I started in the low 30's and was going to let them bleed up to a target pressure of around 35. When I came into paddock they were at 38. I was a 1/2 second off the lead in bump. I had someone who volunteered to help check tire pressures thinking that lower would be better. I ran the fronts at 32 and the rears at 30. I could feel the tire folding under itself and the car was hopping in hard, tighter cornering. I let the pressures build but they never got above 35 and my times were pretty spot with morning runs while everyone went a bit quicker with the cleaned up and rubber-ed in course. Until the last run, the car was hopping up front due to low pressures. I had also tried adding a bit more front rebound. I think the rebound helped but the tire pressures robbed any benefits. I cut a number of 60's in the high 2.1 range.

    The forecast today looked like rain and it was cool. I was 7 tenths off of first and decided to put the Bridgestones on to get some more data and possibly some wet practice if had rained. I hadn't run Bridgestones yet at a Pro. I used the 215/45R17 on stock rims. The 60' were about 1 to 1.5 tenths worse than the BFG's but that was due to start surface changes and similar for other cars. They did seem to have just a bit less wheel spin than the Rival S on course in the hard offsets and "pin turn" finish. I'm not sure how much of that is tire diameter (Bridgestones are 1" taller) and wheel weight difference between Bridgestone on OEM and Rival S on Sparco rims. I finished 7 tenths back even though I had found three tenths on one side of the course as others gained time too. The run I did gain time (42.2) felt great compared to the other runs feeling good (mid 42's) and the OK runs (high 42's). Overall, I felt like I drove similar to what I did in Blytheville though I didn't have a run that felt as good as the 42.2 in Blytheville. I think I could have found a couple tenths more yet had I stuck to the BFG and driven similarly this morning.

    Ron is good comparative data. We both have been running BFG's as well. I was behind him by a tenth in Blytheville on index and here he was .6 ahead. I felt like I had at least another .4 to .5 seconds if needed of sand by not using third in Blytheville. In talking with him, he mentioned the Mini did well digging out of the final pin turn with the mechanical diff. Between that element and the wheel spin in the hard offsets, I think that would account for most of the time change. Dennis was previously on Hankooks in Blytheville so much of his jump on index is likely due to the time difference between tires and his car also did well digging out of the tight turn and maintaining traction in the hard offsets. Charles said the GT3 eats that stuff up too. The top three put on one heck of a fight at the end being separated by only .011 total! Congratulations to Charles on the win! Sam is really starting to get a feel for the Fiesta too. On one side he was within a tenth of my fastest time and had he duplicated the efforts on the other, the gap would have really narrowed. Also of worthy news, Greg Reno is coming back to H Street this weekend at the Tour and rest of the year. He will be on normal stock springs(not JCW) and stock shocks this weekend which will probably help if it rains but right now it looks like we might stay dry. He will be on his tried and true competitive setup in the future.

    Trev, sorry you didnt' make the Challenge. I think you're right that the tight stuff demands the stock bar -- hoping the Tour course is wide open for you.

    Thanks Des...after having a soft index last year, I was due to feel the other side of its effects. First challenge that I haven't made which was a bit of a bummer. I have a bunch of personal stuff going on so it was nice to be able to spend the afternoon focusing on that. I need to also correct my above post about the 60' being a tenth off for the Bridgestone from the BFG. The 60's generally speaking were .1 to .2 off Saturday afternoon so they should be on par with the BFG's. The difference in grip was due to the aggregate voids filling with rubber.

    This morning was tough mentally with personal stuff going on and knowing Greg in the Mini was going to be very tough to hang with in wet conditions. The Bridgestone felt good in the wet. The rear shocks were definitely hurting the stability of the car and I was sliding the car at the smallest slip angles possible through much of the course. Fortunately there were no large offsets or tight turns other than the start though the drag finish offset that. The drive felt really good today and last run felt great though I thought I had coned it away. Dennis Sparks went on to win the Super Challenge, congrats Dennis!, after placing 2nd in Bump with us. He was working course and had some kind words when I saw him of how smooth and on top of things I looked. I mentioned on my last run, I thought I may have clipped some and I was waiting for the call. He laughed and said it looked like they checked every cone in the thread the needle section on the back straight. With all that is going on, having thoughts tearing at my concentration, I love that when the clutch comes up my head somehow cleared and it felt absolutely blissful dancing the car through the course. Greg said he was sitting at the line and heard my time and said some comical words for the camera. It motivated him though and he also laid down a smoking fast run jumping ahead of me by .009. Nice job Greg! The first time I would have liked to have had video. Would be cool to have my and Greg's runs side by side and any differences/similarities. Hoping for dry runs tomorrow, course looks Fiesta friendly.

    Trevor if it's wet tomorrow give sport mode a try. It's magic! And great to see top notch mini fiesta battle at last.

    Kept it a battle but ultimately I couldn't extract enough out of the Fiesta on the Bridgestones to find the time to put me in the lead and Greg got me by .096 in the Mini (on stock shocks/springs). Congratulations Greg! I felt like I had a good drive today and the course would have possibly favored our power but the way the e-diff works (or doesn't for that matter) with the bar really didn't seem to provide much advantage. With regard to the Bridgestones, neither Greg nor I could find much or any time on the Bridgestones. My times got slightly better and then worsened even though I felt like my drive was better on the third run but the time was slower. Ron said it sounded, looked like the tires were falling off a bit. Greg felt the same way. My preference is the BFG. Fortunately mine haven't corded yet and I will flip them and hopefully get at least another 25 or so runs. My preference for feel is definitely the BFG at Lincoln with adequate pressure but then again, it will take a fresh set to cover the Pro and Tour due to the way they seem to be wearing. Ron flipped his after about 25 runs on a Mini S.

    I had been seriously considering jumping back in the Focus and think I am going to do so if I can get tires for Mineral Wells or if I can't get tires, hopefully a competitive co-drive in G Street. I felt way more connected more often to that car on course and miss that feeling. The Fiesta has felt that way at times but it is rare. Haven't had much buyer interest in the Focus and already have some in the Fiesta so hopefully it will be easy to part with. If anyone is looking for a fully prepped car, send me a PM. Not going to part anything out though only selling the complete setup.

    Trev, this battle needed to happen. Give yourself a few days to digest the result, because it's f***ing Greg Reno who beat you by an eyelash.

    I'm thrilled it's a two-car class again. Less thrilled than I would be if you decide to go back to GS, but there you go ... I think it's a terrific result, and it makes me think more of your driving, not less.

    It's a two-car course/weather dependent class again. The cars may have had similar times this weekend but they have a completely different way about going at it and it really is a toss of the coin as to if that will favor the FiST or the Mini. If I wanted to gamble, I would go to the casino. If they could produce similar times on all types of courses with similar dry/wet conditions, then I am all for it. I race because I want to see who the best driver is not which platform was more competitive on any given day based on course conditions and weather. I had a good drive and have no concerns with my abilities just not enjoying the car as much as the FoST and G Street is more spec class which I do like because it takes platform out of the equation unless it rains with the AWD cars in class. I'm not implying in any of this that the FiST is a better or worse car or that I am a better or worse driver than Greg. What I am saying is that the FoST is the better car for me.

    A little more info on tires. After I had time to set down and count, I have 37 runs on my BFG's and they have not corded. All except 5 of those runs were on concrete. I do plan on flipping them. In speaking with the BFG engineer, the sidewall construction is the same so that is not a concern. They are aware of the wear and sounds like will be working on that and tread design to help. It is nice to see them at events directly involved and the engineer was very candid and open to input.

    I would say that my BFG's and Bridgestones are wearing pretty closely at this point for me given the number of runs on each of them.

    I am no longer a FiST owner. I wish you guys all the best and hope to see the cars continue to develop!

    For the first time in 23 years, I own one vehicle :happy:

    Trevor,
    I want to publically thank you for all the help you have been with the development and advice on the car. I know I would have been lost with out it. So thank you!! I'm sure I will still see you around of course.

    Thanks Ryan, I appreciate your help as well! I'll be around for a bit until the house sells and things line up some place warmer.

    Trevor, what are your thoughts about having Tirerack shave and/or heat cycle a set of Rival-S for Nationals? They also have a rebate until June 14th, but I wonder if I should wait until closer to the Championship. Thank you so much for previous feedback and any you may continue to provide. I look forward to pulling for you to win GS. I know you will face top competition there, particularly Mark, but you are absolutely capable of winning this year.

    I think shaving is only going to reduce the life of the tire on the shoulder area. I haven't seen anything that leads me to believe shaving would help with wear on the FiST. I plan to scrub mine in a parking lot. Skid pad circles preferably on a warmer sunny day to build some heat and give them a moderate heat cycle/scrub. I don't think there is going to be a better time to buy. Glad to be of help and will definitely continue to contribute where I can. I appreciate the support. Mark will be a tough battle and this year it looks like he will have two Jones' after him. Matt Jones has been doing well in the FoST too among a few other names that will really step things up further this year. I am looking forward to the challenge!

    Darren Seltzer is now registered in HS for the Championship, so the Fiesta ST has completely changed the class turnout. Reno, Savage, and other top drivers are definitely capable of beating Darren, at least away from F Mod. I look forward to the competition.

    I saw that as well. I look forward to competing with a lot of top drivers. I'm not at the pointy end yet but what a good way to measure.

    Not to derail the thread but I may be looking for an HS ride in Lincoln if someone has an open seat in a prepped car. (I don't know yet whether I'll be able to get my Mustang out there and back in the time I have -- it's 1700 miles each way!)
