I've installed a T1 suspension kit in an 05 C6. can anyone share info on set up? Also looking for clarification about the new brake rules for SCCA T1.

Yep. My best advice is take it to a pro shop somewhere and have it set up correctly - ride height, cornerweighted, zeroed sway bars, alignment, etc. The Phoenix Performance guys in Pennsylvania do OUTSTANDING work and are pretty much the only ones I really trust to do the suspension stuff. It's well worth the trip and I doubt that anyone knows more about that setup than them!

If all this means you're coming into T1...then welcome aboard!!!!!!

"Correct Touring T1 item 2 (page 55) as follows:



2. Chevrolet Corvette C6 Coupe (05-09), add the Grand Sport (10- ) model at LS3 weight. Add the following note to the Wheel Size (inch) column: (Grand Sport must comply with these wheel specifications). Add to the notes: C6 LS2 may upgrade to the Grand Sport brakes with no weight penalty.



Add Touring T1 items 3, 4 and 5 (page 55) as follows:



3. Chevrolet C5/Z06, replace the Brakes (mm) column with the following: (F) 325 Vented Disc (R) 305 Vented Disc; may use two-piece steel rotors with aluminum hats up to 5% larger than 325/305; may use two-piece steel rotors with aluminum hats up to 5% larger than Z51 rotor size and any four piston caliper with 18 x10in front wheels at a 50 pound weight increase. Add to Notes: Any brake caliper pistons are allowed; may use the Wilwood SL6R brake caliper at no penalty.

4. Chevrolet C6, add to Brakes (mm) column as follows: may use two-piece steel rotors with aluminum hats up to 5% larger than Z51 rotor size; may use Grand Sport brake package. Add to Notes: Any brake caliper pistons are allowed; may use any four piston brake caliper at a 50 pound weight increase."

so you can use the GS or crappy wilwood kit at no penalty, or get a real kit for 50lbs. Sounds like the GS kit is the way to go.

So can you use the GS kit WITH decent rotors? I'm not sure if those are within the "5% larger than Z51" criteria, but should be close????

340mm * .05 = 17.
17 + 340 = 357mm, so the 14" GS sized rotors (355mm) are legal.

I just hope the GS/Z06 calipers hold up to the pounding.

was the Z51 rotor in C5 same diameter as the C6?

All C5s had the same brakes, including the Z51 and Z06.

the c6 z51 rotor is about .5 bigger than the c5.
