Great man, can you tell if there was any contact to the tires by the body?

Re: first time out with 325s
that pressure seems really low to me, but i'm also running less power at the moment. did you get a decent clean pass in?

Re: first time out with 325s
I guess its because my car weighs 3020lbs with me in it that it requires the low pressures I haven't seen what others with cars as light as mine run for pressures. I had the one clean pass 1.45 60ft, 4.400 330ft, 6.85 @ 99.85. I have way too much gear. I bought a rear from a guy that ordered it with 4.30's and my turbo doesn't like them at all. I going back with a 3.23 or 3.42.
