Regardless of what you read, the Sonic does not like additional boost below 2500 RPM. Stay conservative, very conservative.

With a few tweaks and a good set of OE size tires (RE-11) you'll find it to be a riot. With the THR you could run out of talent. With the Sonic, it is all good as long as you remember to turn off the TC, SC and don't run out of throttle to pull you through the turns.

John Buttermore had a strong influence on the Sonic. His former boss (trivia question: Which GM Performance guru's favorite car was a Cobalt SS and is now running a Sonic on track?) responds really well to 6kg front and 10kg rear springs. Ride is not good with the race spring setup, but the handling is sic.
