I took the SS to the track for the first time yesterday and ran a best of 13.07 at 107 mph. I think that the Nitto's slowed me down because it was dead hooking and first gear felt very lazy. I was side stepping the clutch at 2500 rpm and it just did'nt have the ***** to cary it. I'm thinking that a gear change to 4:11 will help out alot. I think I could have went faster with a little tire spin, but I have a Tranny problem to fix before I can even think about a gear swap. But I wont wait too long, Next time out I will be in the 12's... The Nitto's and completely stock suspension are working awsome and I don't think I will change much until I have to.
