Also for some technical data.
Stock Rims and Tires: 60 lbs
Curva's with Tires: 54 lbs
I went with Curva Concepts C7's in 20 inch, 8.5 inch wide with a 38 mm offset. They sit pretty damn flush and I like them.
My tires are pretty much new Conti's 245's. The car cut a 1.77 on them at the track.
I don't drive the car much so, I just couldn't justify spending another $1200 for a new pair of 275's and the wider rim set up. The good thing is, I can fit a 255 on these rims easy, possibly even a 265. So either way I win.
I am going to install the upgraded trans mounts, DP's, and tips and head back to the dyno.
Hopefully she cracks 400 awhp. If she doesn't, I will give up on that endeavor until the upgraded HPFP and GH turbos go on.
I will then head to the track, and see whats happens. I have had some spin and shudder/wheel hop in the past. I will see that the new rims and mounts do.
If it still spins, I might just throw a pair of drag radials on a set of flowers for the fronts and see what happens. If works it better, I will buy another pair of Curva's and mount the drag radials on them. The car will pretty much live on drag radials for the street for the future. Then when I go on a road trip, just take the drag radials off and throw back on the Conti's
