    2.57 is plenty respectable, big lift for the Kink there although I can't blame you for that. It's a scary place.

    I should also mention that I've been going to Road America with my father for about 30 years now, I've done a few touring sessions in both my car and his but have never done a track day.

    That said, to this day when I ride around the track with my father behind the wheel I get nervous. I know he's a very good driver and knows the track like the back of his hand but it's unnerving watching the brake markers fly past and he's still hard on the gas.

    This is his car(my son riding shotgun), we're headed to R/A again this weekend with it for the Fall Festival. :)

    He runs consistently in the mid 2.50s with that car and he could push harder but since there's nothing to gain from it he just goes out and has fun.

    Nice Car and ya i got to over thinking the Kink and ya know there is what 3 ft of grass and a concrete wall.. Plus one of the later laps the Mustang ran over its inner fender going into the braking zone on 12 Canada Corner so that makes one think too.. fun fun fun Hi Speed HyJinks no doubt :)

    The Kink is a good place to be careful until you're 100% comfortable going faster through it, no room for mistakes and the concrete walls are rather unforgiving.

    At least Canada corner has decent run off and gravel before you hit the tires, you have to screw that one up badly to get into the tires too.

    It will be Fall there this weekend with temps in the 50's/60's during the day and in the 40's overnight. Will I see you possibly on Friday at RA?

    You're welcome to come look for us, We're usually in the grass paddock area on top of the hill on the left between the Gearbox and the gas pumps. Look for the Healey above or my silver SVT. I'm easy to spot, 6'6" and 225 lbs.

    We hope to get there around lunchtime on Friday, my dad will be there before my son and I. We're also having a small get together of Focus owners on Saturday evening down in the carousel campground that you'd be welcome to join.

    I've been on the road and just getting caught up on this thread...

    I didn't skip your point at all -- maybe I initially misunderstood it. You really mean the older "SVT Focus" here, right? I don't know that car, but know it had some interesting features. By comparison, it was more of a factory tuner car than the current FoST/FiST we have today (accounting for some less-than-optimally engineered systems). For the purpose of this discussion, I'm sticking to cars I know. The current gen Focus ST has the problem we have, only worse (as it relates to rear pad wear and overall brake performance). I've heard it said that the Focus ST is a "fast one lap car..." and that seems to be a moto pundit consensus. The TVC simply cooks the rear pads, and eventually the entire system. It's one of only a few cars that have ever completely melted down in MT's track testing under the very capable hands of Randy Pobst -- his first).

    Anyhow, like most of us, I have a lot of varied car experience (call it 20+ performance cars, 30+ total) . I personally have never had a car wear its rear pads more than the front. Yes, doing so really would suggest unconventional compounds or sizing. The real point that I'm making is that for OUR FiST, I strongly believe TVC is the cause (just as I do with the FoST). Moreover, I personally have lots of track experience with the FiST. My car burns STOCK front brake pads at about 2x fast the rears. Now that I'm exclusively running Porterfield R4 (race), it's too early to say. Preliminarily, it feels about the same.

    Said plainly, I think TVC caused this problem for RodMoe. Different tracks can invoke more or less TVC control (a point not lost on me). Using more TVC, for any reason, means more rear brake use.

    I'm making assumptions and drawing independent conclusions like anyone else here, but I'm doing it based on my own first-hand experiences. I'm killing my TVC system (but hopefully not ABS!). To say it again, TVC is pretty darned cool on stock or near-stock cars for the street. My particular car, with its particular mods no longer likes it. I love race-based stability systems. A good friend owns a national Time Attack record with a monster 350Z. He's fast, but freaking rocks with that racing stability program. It's almost necessary to harness his ~1000HP or so.

    Edit: TVC comment for clarity.

    which leads me to believe the Fiesta/ Focii ST's utilized in Fords Octane Academy, had the pads replaced with a differing compound, those cars were absolutely HAMMERED, day inday out with ZERO issues.....and for one hell of a lot more than one lap......

    I'm learning about the new cars all the time, wasn't really aware of how the TVC functioned on these cars, I just knew from experience how hard R/A is on brakes.

    Never stop learning. :)

    Right on, I'm right there with you. :)

    I'm still on my quest to reversibly defeat TVC and I'm afraid I'm going to do something that will make it rather permanent. No tuner has responded with anything, and I'm pretty sure it's just a development thing. We may one day have that as a tuning option. Either way, I have until a couple track days in mid-October to figure it out. ;) My car really isn't quite right with it enabled these days.

    I'm going to PM you now about a couple related track day purchases.

    Odds are there's a way to shut it off but you can be pretty sure Ford won't tell anyone how.

    So...in cruising your FRPP parts list, I just saw this beauty:

    upload_2014-9-15_12-5-32.png

    I have since asked you about it via PM, but this is absolutely relevant to what we're discussing here! If I can simply swap out my ABS control module for this one, I'd be super happy.

    I'm also really happy about the AC delete kit you have, and I want to buy both now if they are the correct application for our USDM FiST! :)

    It appears that is the solution, I have actually seen that before but never read the description :headbang:

    $247.50 plus shipping.

    BTW, I should have mentioned that my dad actually got pole for the Sheldon Cup race on Sunday at R/A.

    [​IMG]

    That's me holding the roll bar and our friend Rich (30+ year Formula Ford driver) taking our picture, pic above taken by another friend.

    The pole was a timing error, they had him at a 2:32 (actual was 2:56) but after 30 years racing my dad figured he'd take it and just make his car real skinny at the start. From the start/finish to turn six he let 23 cars past and got back to mid-pack where he belonged. That Porsche right behind him won the race absolutely running away from the field and lapping a good portion of it.

    Great time though. :)

    Our friend Jeff (yellow Healey #28) was involved in an incident coming in to turn 5 on Saturday afternoon, a Lotus 23 lost it, hit the wall and came apart, Jeff almost made it through but the front suspension of the Lotus bounced off the wall and slid out into the track and bashed in his right front. With some direction from Tom Kovac of Fourintune, the drilling of a few holes and the use of my dads Expedition we managed to get it straightened out to race on Sunday. Didn't take any pictures of the damage, poor form you know.

    This is a very fast Healey, runs about 10 seconds a lap faster than my dads car,

    [​IMG]

    And another close friend with a Healey, also a Jeff, this car was finished last year. It was a seven year home build and its an absolute work of art. Won the race car concourse last year as well as the Road & Track "Car we'd most like to race" award.

    It was cool, wind never stopped so even when the sun was out it wasn't warm. I've had worse weather there though so I won't complain.

    Yup a bad weather day at the track is still better than any day at work LOL

    Better late... :)

    I have more questions about this, of course -- but since it's the correct application, I'll just give it a go. I wonder if it has a more aggressive ABS lock-up program in addition to eliminating all stability/TVC? It's priced like a replacement ABS module, so it may just be a new program sans stability code.

    Okay, I'm really happy about this! I'll follow-up offline with you for this and other parts.
