Not much on suspension, I have pdaft sway bars, control arms and that's it, stick everything else, I cut 1.7's at best, I am not too,violent off the line, but turbos do kick in hard top end.....all of this with original 20" wheels and the 555r's.....you can dip into 10's with 580 whp on a good day, not in the summer.....good luck!

Good luck with the new trans. What have you done to the suspension? I am running a little less power but I am hoping to dip in the 10's when I get back from deployment.

I ran 10.9's on stock engine but broke trans, I now have a 416 ci forged engine pushing a street mild 10 psi and I'm working on a track level that should push to 18-20 psi, I am in the middle of a trans swap, I've broken 2 6L80's and got tired, so I am installing a 4L80 which should be ready this week....I also have a 3600 stall....feel free to ask me any questions, I've had my tt since 2009! I run mid 10's on 14 psi and about 680 whp

Hey, I was just wondering what you have done to run mid 10's with 555r's?
