The coilovers came with camber plates.

OK, that's great. I found that I have mine maxed out at -2.7 degrees and its still not enough based on tire wear.

[GodLovesUgly]

which camber plates do you have??^^
that's good news about the kumhos, did you get the square shoulders or round?

[wrc_fan]

Round kumhos and I am lucky enough to have 2 sets of LCR race camber plates.

[ThatOneFocusGuy]

I think mine can give me up to -3° of camber.

Where do you guys order your tires from? Having a hard time finding tires that are available.

[wrc_fan]

Tire rack, I have them delivered to a local shop for install.

[ThatOneFocusGuy]

Tire Rack is almost bone dry out of every autocross worthy tire at the moment.

[GodLovesUgly]

give it some time, they will stock a ton for the upcoming season.
i generally get my tires a day after i order them! they usually ship from from NV.

[ThatOneFocusGuy]

I got about a month and a half before the season starts here. Hopefully they restock by then.

Unless they have changed the rules there are no limitations on Wheel dimensions.

I would go with a 15X7.5 wheel and 225/45/15.

Last time I checked 18Racing.com had 8 flat back Rota Slipstreams 15X7.5

If you want a reasonably priced 4 piston brake caliper upgrade, I can sell you one of my Focuzax-7 caliper bracket sets. >> See Post Here << (mounts a Second Gen RX7 brake caliper to the Focus Spindle) You will also need 05 onwards hubs. But this will get you a larger 10.9" rotor instead of your current 9" rotors.

Oh and the RX7 calipers are aluminium, so you will probably save a couple of lbs of unsprung weight, or at least offset the weight of a slightly larger tire. Also the RX7 calipers allow for quick brake pad changes, which makes it much easier to swap in a set of Hawk HP+ or any other autocross brake pad, then drive home on your average quality low dust/low noise street pad

If you buy the 15X7.5 slipsreams and do this brake conversion you will need 15MM spacers for the Rota's. Other rims will clear the calipers better, like the Enkei J5? RJ5? RS5? (not sure of the model) which I was using before I purchased the Rotas. It depends on how much dish is built into the spokes, not just the offset.

Regardless of what brakes you are running, I advise installing Stainless Steel Brake Lines for improved brake feel and response, since it's not unusual to win/lose and autocross on .01 seconds.

You will need SS Brake lines to perform the RX7 conversion, if you decide to go that route.

If you want extreme adjustment range on camber plates, I would check out "K-Mac" a austrailian company that makes a pretty radical adjustment plate. http://www.k-mac.com/pages/camber_caster/camber.htm

I had a friend custom fab some plates for me that somewhat duplicate that set-up and I'm sure I could get about 4degrees negative camber If I maxed mine out. Pretty sure the K-mac units deliver similar results.

I would seriously look into getting a limited slip differential, and if you feel real adventurous do a MTX75 swap somewhere in the future.
