Does anyone know what the backspacing is the front GXP wheels? I don't want to use Mustang wheels so I've figured I'll buy some 5-115mm or 5-4.5" wheels in 17x9 or 17x9.5; looking at some Centerlines right now:

The 2 visits to the track just wind up in frustration since it won't hook so I'm going to slap some ET Streets or Hoosiers on the bitch so it hooks.

Also, any input on running 275/40/17s vs 275/50/17s? With the 50 sidewall the diameter is 27.8" and the 40 sidewall is 25.6" (to the stock 27.0x) I know as it sits now with just the DP/cutout my best trap to date is 104 which is pretty much fuel cut off in 2nd. So if I go with the 25.6" I'll be shifting into 3rd earlier on the stock setup. But then again better 60 foot = lower trap speed. Buuttt more mods = faster trap so I'll be using 3rd either way.

After more searching I came upon this ad:

Lists the fronts as having a 40mm offset; according to this link:

That equates to just over 6" of BS. Time to call up centerline tomorrow and confirm!

I put a set of centerlines on the MCSS one time.
