I have goal, I work with a guy that was a 04 srt-4 and the thing is hot!!! the car ran a 12.71 @ 107. it is water injected and runnig about 20 Psi of boots, on a stock turbo. Now the really question how can i keep up with him with out getting into the heads and cam,nitros,or turbos? I was told some 4.10's and long tube headers and the stuff i have done already in my SIG will get me close, is this true? Or what else will putt me close?

 

I well setup suspension system which might kill your 10 bolt. I've seen people drop a second off there time w/ just suspenion work.

The 4:10's & headers are a good idea. Suspension is also a good idea like mentioned above. Maybe some 1.6 RR and drag radials. Have you been to the track to see what you run now?

 

Considering you have an m6 all i have to say is be careful too much traction is a very bad thing. Headers,rockers,gears,tires, suspension..
Heads/cam should get you there on street tires spinning the whole way.

 

YOU CAN'T!!
