What's your wheel/tire setup? Any other weight reduction beside the SRA?

Lot of folks don't realize that good tires not only help with imporved 60' times, but also help with traction with gear shifting. And by throwing that solid rear in there without removing any weight from the front of the car, you've actually just made your front to rear weight transfer dynamics even poorer.

A tubular K member, lightweight battery up front, removal of the front sway bar, and a good slick/skinny setup, should get you to 7.20's at worst, without even changing the car's power. So many folks just throw power at the car and expect it to perform at the track, but it usually won't unless the suspension is setup up reasonable well.

well the class i run is a true radial no dr or slicks alowed. i need it to run 7.45 to 7.50 on the true radial need all the help i can get with wieght tho. did put the drs on today and went 6.92 with a 1.54 60 ft

You do drop a significant amount of weight with a tublar k member.
More boost and more hp should help you go faster also. If you can plant/use that power.

op, what kind of power are you puttin down?
