How is everyone launching their A6 ZL1's? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I plan on mainly running Autocross at C5 fest this weekend. But I may try a pass or two down the 1/4 mile. So how is everyone launching their Auto ZL1s? In a specific PTM mode? No PTM and just killing the TC? What RPM? Feathering throttle at all? I probably won't be on DR's, unless someone lets me borrow theirs. Currently on michelin pilot super sports

all aids off...traction/stabilitrak off. Preload against the brake to 1000rpm and gently squeeze quickly to the floor. With drag radials you can do this almost immediately on a well prepped track. Transmission in "M" and do not use the paddles. Let the computer shift for you. Get a routine and adjust small things until you perfect the launch according to available traction. I have tried many different launch rpms and loading rpms more than 1200 doesn't help the 60' very much. With street tires, you still need to do a burnout but launching needs to be gentle before full throttle. Air down the rears to 22-24 psi to help the contact patch and soften the launch. Suspension in tour or sport...I see no difference.
