    I will be interested in how the Hankooks do...they may be my go to tire since the dunlops are sold out.

    The missing shock-mounted counter weights may be an issue but I'm not sure. My first guess is the shock rule would allow the change but I'd prefer to get that in writing.

    How does one get in the loop as to when the shocks will be available? Also someone needs to ride herd on Koni to make sure all the dimensions ate correct. I'd do this myself but they are already upset at me for pointing out back in 2006 that their original design for their NC Mista shocks wasn't legal.

    Not my thread Alan. I was just pointing out that Koni is working with a FiST and shocks are in the works. Maybe we can get the RRAX poster to join up here and keep us informed :)

    I'm on that board. There isn't much work being done yet. Just initial work test fitting existing components.

    Oh, and one thing, we like to keep a low profile on that site, so direct links are going to be discouraged, or remapped to gay porn or something. I'd likely cut/paste the quote instead of linking direct.

    Hadn't heard the low profile thing, but I will remember that going forward.

    Some new bling. Literally.
    215/40-17 Dunlop Direzza RII
    Mounted on a set of chromed Focus SVT 17x7 et49 rims I found locally on CL. Original owner bought them new and had them chromed before putting them on his focus. They are a bit pitted on the back but will work well for autox. Not the lightest, but can't beat the price.

    Not sure about the looks, but what they're wrapped in is much more important. Perfect time to get them before the match tour. It should make G-Street a bit more interesting.

    Don’t be surprised if you need to use some thin spacers with et49 wheels. Make sure to check carefully before driving in anger on them.

    Nice wheels I thought of going chrome too but a powdercoat deal came along i couldn't pass up .. (free) yes these wheels are heavy as the stock ones and pretty tough I use them for my wet tires and some Daily driving as I like the Mich SuperSport Pilots AS3 that much..

    Have you needed to shim them? Are they the same wheel I posted?

    Des! I wish I could tag you like facebook, but I digress I am curious to see if the 235s rubbed at all?

    Sorry, thought I had updated. The 235/40/17s fit OK on the stock wheels. They rubbed quite a bit on the +42 on the outer fender edge. On the stock wheels, they seem to rub only when the front end is sharply compressed very quickly -- like couldhavehadav8's photo. It hasn't happened often at all, seems to happen less as the tires wear, and occurs with both the Federals and the Dunlops.

    It does not rub at all in the daily driving I do, which is limited.

    That said, it clearly can rub. I don't mind replacing a fender liner or whatever, and it's nowhere near that point, but I could see rubbing a hole through it in a few seasons.

    So they barely don't fit. Good to know.

    In my world, they fit, but just barely. :)

    If Hankook would make a 245/35/17 RS3, I would go for that, too!

    So if you were to speculate, what would be an ideal offset for the 235/40r17?

    Regarding the 235/40, the stock rim worked better than the 42.

    What's below refers to the 245/35, because I misread Cligedy's note!

    I'd try a stock rim first, because I'm cheap, but the section width would be about .3" more than the 235, which fits with about half a pinky to spare.

    So maybe a 42?

    The Toyo in that size is only 23.8 tall, about the same height as a 225/45/16. Of course, it hates to be pinched.

    Tire rack is showing 24.4" tall for the Toyo R1R in 235/40-17... Same thing for the ZII. That will increase top speed by quite a bit (and raise the car) but you will also be giving up thrust capability. Might help put the power down some though, since you will have less torque at the wheels!

    Des, we should lay our wheels side by side and see if the 235 is any wider mounted than the 225/45-16. My guess is that wheel width will result in them being the same.
