Guys i just perchased a 97 Z28 and put Moroso CAI and Flowmaster muffler and i have a 315 drag radial and i run at the local track

60ft -2.1 i was spinning with 315 at 11lbs 80 mph
1/4 13.80 104

is that good for a stock car with 17x11 on the back?? just wondering???

p.s. its a m6

thats pretty decent for the mods you have. I would see if you could goto the track when it has better track prep, or if there is a better track. Cause I run 2.0 60ft with basic street tires. Did you heat them tires up really good?

you can probably shave about 3 tenths off if you got a good launch. alot of peeps do 2.0 60' bone stock

yeah i heated the tires up im hoping for a 1.9 60ft if so that will drop my et's to a 8.6 and 13.60 i cant complain with that on a mostly stock LT1

Don't run DRs under 18 psi, you're just hurting your times. Under about 18 psi, they start to cup, and you wont get good contact with center tread (they will ride on the outer edge around the sidewall) and the increase in internal friction will slow your MPH down a bit
