right now ive got 275/50/15 et street radials on my car. i put on some 325/50/15s and the car picked up about 1 mph and 1 tenth i was looking to buy another set of tires for the track either a 325/50 or a 28/13.5 et street anyone running 28/13.5s? it is supposed to be the same.

 

Definitely will stick out a bunch, but if you're ok with it. I'm running 28x12.50 ET streets with 6.5bs and a bunch of inner fender mods to fit them. I don't like the skateboard look. Also, with the taller tires did your 60' drop? Was the 1mph from different air density? That 325 is definitely a 9 second tire for sure and I can't see it for your high 10 second passes. Maybe the 28x10.50 ET drag would be a good choice or perhaps the 275/60 since the extra height might have helped it?

 

my 60 was about the same maybe a little better on the bottle but dropped on the motor. the runs i made were back to back it might have been hotter when i ran the 325s. i liked the look of the 325s on the car and i want to hook. i really didnt want a full slick thats why i wanted the 28/13.5s they wont stick out anymore then a 325 will they?

did you have to relocate the springs to run a backspace that big? any pics of the fender mods?
