I ran at the track for the first time in my 98 z28. The elevation at the track is over 3000 feet. I was wondering if the trap speed was pretty good. I know the ET can be lower with the 100 mph trap speed tho. I had a 2.9 60'. Any suggestions how to get the 60' lower w/o breaking the stock rear? Only mod is SLP loudmouth cat back.

For only exhaust and that elevation, and that bad of a 60', I would say that is a pretty good mph. Now just get some stickier tires and bring that 60' down to a 1.9 and you should be low low 13s/high 12s.

Drag Radials. That sixty foot is horrible. I had a better sixty foot time than that in a Suzuki Aero...

Yeah, that 60' is insanely bad. I've had better 60's spinning all the way though first and into 2nd. My 17 second GMC Jimmy has a far better 60'

Better tires + practive will make more of a difference than anything else.

I always have a theory of don't throw money at the car, my suggestion, hit the track up 3-4 more times, get your launch down...

Drive around the box, spin the tires a little to clean them off, drive up to the line, brake torque it up(not sure the RPM, experiment), and go from there.

Even with sticky tires I think you would just spin the **** out of them too then be just wasting expensive tires. Your new so you just need a little practice, rarely peopel pull their best times first times to the track.

your car is capable of 13s easily, at your altitude.

You really think he can get into the 12's with just tires and exhaus?
