I know this kind of question gets asked a lot, but I just wanted to get some input on what I can expect with these mods. My car is a 2001 Z28 4A. My mods are as follows: Borla full cat-back, SLP ram air, MTI lid, SLP 160 thermostat, and the SLP smooth bellows. My best time with my exhaust only was a 13.499 with a 2.215 60 ft. time. Thanks a lot for you're input guys.

 

Get some drag radials if you don't already have them. That will make a huge difference. If you got a 13.4 with that 60 ft., you should definitely be in the high 12's (12.7-12.9). That 60 ft. is killing you.

Thanks for the reply. I did consider buying drag radials but im concerned about how they wear. I dont wont to be replacing tires every 4,000 miles What would be the best choice if I was looking for a combination of tire life and grip? Would BF Goodriches be a good choice?

 

To be honest the BF Goodwrinch Comp TA are really good tires for the highway and for grip. They hook up really well in my opinion. I just bought mine about 6 months ago and I've probably put 6,000 miles on them. I've also noticed that they are a little slick in the rain, but I guess any sports car is that way no matter the tire.
Also, if I had it to do over again, I think I would probably go with the Michelin Tires I just like the way they look on the rims.

Drag radials wear about to 20,000 miles i would say, but then again if you are doing a few burnouts every weekend they will be gone in a matter of a month or 2. They are extremely sticky. I had some 275 555r nittos on my 99 Gt and they wore about like the gsc's on my Z.
