Wider wheels?
I'm wanting to throw on wider wheels in the back so I can get more traction. Someone told me that if I did that the car would go into a "limp mode" and always think that I am spinning my tires and what not and the speedo would go out of whack. Is this true? If so how do I get it to where it won't do that? I'm wanting to go with a 17x11-12 for the rear.

as long as you keep the rear tires at least .5" larger in overall diameter than the front tires it should still allow the traction control/active handling to work as designed... you can also turn it completely off and run whatever size tire you want... tire compound and sidewall are more important than width but an 11" wide wheel should fit fine as long as they are the correct offset

So if I get a 17x12 rim with slicks, I have to make the height of the setup the same as the stock setup? For smaller rim add thick tire, and for larger rim add thinner tire?

best to ask in the drag racing section what they are using. you don't necessarily need the wide rim to achieve what you need.

what matters for the abs/tc stuff is the tire height. oem tire height is 26.7" tall. so you will need to find a slick/drag radial tire with that height for your rim diameter (17") and enough width to fit the wheel. problem is finding a 17" tire to fit your needs. you may have to drop to 16".

Sounds like a better tire would do the trick. My '04 Z was making nearly 400rwp, and I rarely broke my Conti ExtremeContact DW's loose. FYI, I was running 295-35-R18's out back. Practice makes perfect.
