Always trashing the 1LE... Very minimal understeer. Keep away

1. Do the math on the sway bars.
2. Drive faster and you'll find the understeer.
3. Tell me why the 1LE has a larger front bar than the ZL1.

Last but by no means least, I never speak poorly of the 5th Gen and consider the Camaro TEAM my friends and believe most of them would say the same about me.

The more grip you have in the front, the better.



As long as the tire isn't over stretched it will be more predictable with reduced sidewall flex. In the front, the engineers opted for a bit more sidewall flex, to let the tire roll a bit more to increase grip when turning. The opposite is true in the rear. With the stretched sidewall you get a bit more rotation in the turns.

The L/28 uses a square wheel and tire setup.

Thanks for summing this up, Pete. I had been trying to figure answers to some of these questions myself, your answers make sense. For a new member such as myself, this saved me hours of sifting through old posts.

I'm thinking about buying an extra set of wheels and track tires. On a stock 1LE, what would you recommend? Would you stick with the 285s on 10/11" wheels? I'm just beginning my research, I see that Toyo Proxes R888's are available in that size. Or would you go with 305s front/rear, and if so, what wheel size?

Toyo R888s, BG Goodrichs G force Rivals which btw have the similar threadwidth measurement as the 305-30-19 Bridgestone tires Pete recommends even though the BFs are 285s and also NItto is coming out with a NT01 in 285-35-20. Personally I like the 305 on 19" setup which is what I may go to as soon as I get my miss matched but handles like a mutha wheel setup sold. ZL-1/1LE wheels are still heavy around 60lbs each and a little more. Get around 50lbs per corner and then begin to feel your car come alive in corners especially for you autocrossers. 18" wheel setup is even better but depends on what tires you use. I am also thinking of 18x10" with Nitto NT05 285-35-18 on all 4 corners, just under 50lbs per wheel.

I am sure it does hurt the time, but most track rules mandate you run with the front side windows down. We ran the Pedders USA Sonic at the OPTIMA Invitational after SEMA in November. We were so under powered compared to the rest of the field they let us run with the windows up. We also ran the heater on high to help lower engine temps

This may have been said, but when you listen to the GM engineer, he clearly states that the stretched rear tire was used (285 vs 305) to reduce rear grip and thus reduce the understear problems that Camaros and Firebirds have struggled with since their inception. The fact that the first statement in this thread was based on how a tire change made the best handling sub $40K car in the world look vs how it would effect it's handling is amazing in itself.

To say it again, the smaller tire was used to loosen up the back end and reduce understear. To each his own, but that was their intent. Each driver should use the set up that makes his or her car run best, or in the case of some in this group.....look best!

So how do matching 305/30/19s work on the Z/28?
