Dammit so I am trying to fix my brakes, and seriously considering the C7 z51 brake upgrade. Which according to peeps on LS1Tech seems to fit 17 inch wheels. EXCEPT I look at my CCW wheels and see there is a 1/2 inch "inset" bump on the inside of the barrel. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/rant2.gif) (IMG:http://www.frrax.com/rrforum/style_emoticons/default/banghead.gif) I went with 17s when I got them b/c they generally fit and I thought I'd be good with them. I didn't buy the new brakes yet but man I am upset. I don't want to have to sell these (along with a set of extra tires) just to buy 18s and spend even more money.

But hasn't anyone else driven in a Mitsubishi Evo, or C7, etc with GOOD BRAKES. Man it puts the brakes on Fbodies to shame. The pedal on my car has almost always been rather mushy. I think for a few months when I had a new MC and new Carbotech pads I had a good brake feel. My friend's Ford Focus seems to stop harder than my car (I realize its probably lighter).
Though, of course I've had 2 FTDs last year so really, who needs to slow down? ;-) I drove a friends CAM-C car with C5 brakes, and it felt no better than my car. Pedal inconsistent- sometimes firm, sometimes mushy, depending on the last corner I took, or apparent engine speed.
My hubs are now good (xtracker C5 hubs on adapters). I'd love to just have confidence they will always have the same feel for each corner.

None of those cars have a semi-floating solid axle that might be cause pad knockback in the rear during hard cornering.

So bigger isn’t better...ummm (IMG:http://www.frrax.com/rrforum/style_emoticons/default/huh.gif)

I can't tell if you are being sarcastic or are disagreeing with me. A bigger rotor provides two things: more mass to absorb heat during braking, and increased leverage for the caliper. At autocross, you aren't putting much energy into the brakes: there are no 150 mph->20 mph braking zones, and the stock f-body 12" rotor with good pads can lock even the stickiest tire.

Bigger is better *for a track day where you need the mass*, but smaller is better for autocross, where you don't need the mass and want to keep unsprung, rotating weigh to a minimum.
