I have 315's out back, but they arent the greatest tires ever. Ive been practising launches and I have them down pretty good. Whats the difference between a track and the street? The track is smoother right?stprorolla49 said:i'd run 25lbs in the back, and 32lbs in the front...just launch at about 2 grand slipping the clutch a bit...if it bogs, raise the launch rpm to 2500 or so, if it spins, lower it....i found out on my street tires i hooked the best at 2 grand....FWIW, i cut a 1.99 60' on 245 street tires, so it can be done...good luck and post up times!
It only takes like 10 minutes to take out everything except the system, so its worth a 1/10th to me1Bad89Coupe said:Keep that stuff in there, it's not worth the hassle for an extra tenth. I say mid to low 14's since it's your first time out...and your car is DFG

theresa bit more to grip onto on the street because its rougher, but the track surface is a bit grippier...you may find that you wont be ableto spin in 2nd gear on the street, but you will be able to at the track....if its your first time, just take it easy, and dont try to impress anyone....the first time i took my car down the track, i was expecting to run a 15.xx with a ****ty 60' and i didnt get my hopes up...i ended up running 14.25@95 with a 1.99 60' on 245 street tires....just have a ton of fun and be safe! its one of the most fun things ive ever done, and thats what keeps me going back again, and again, and againThe Green GT said:I have 315's out back, but they arent the greatest tires ever.

i would strongly advise not doing that on street tires...they are not meant to go that low and at the top of the track, the car will get squirrely....i would go no lower than 23-25 lbsAdam95GT said:id drop them down under 20psi... well the rears.... and tracks usually have an air pump there for you to use....

yea, every 100 lbs is roughly a tenth94gts said:you wont get a 1/10 from a removing the spare and jack. just take the system out.
you have 2.73's right?
my prediction is a 15.1@92 2.2 60ft
Sweet. Im almost empty anyway. Ill just fill it up 1/4th at a time so I dont have a full tank when I get there.sage2k said:also ill be bringing a timing gun if you want to fill up with good gas and raise your timing
