I have a 96 z28 with 88000 on it and I am going to the track for the first time on april 15 and was wondering what I am going to put down. A4, I have a SLP loudmuth cat back, K & N FIPK and nitto 555r drag radials 245/50/60.

 

high 13's

 

13.7-14.0 with the drag radials , as long as u did a tuneup recently

street tires will proly keep u in the 14s unless u car has some hidden powe/traction

 

I would venture to guess you will be in the upper 13s as well. It wouldn't hurt to clear out some stuff also like the spare tire&jack, run a 1/4-1/2 tank of gas, and pop out the back seats if you are really motivated.
