The Shelby Razor 6 have the right lug combo but they have a 30mm offset and 5.9 of backspacing. They are 20x8.5 wheels. My stock rims are the chrome clad steel which i think are 17x7.5. Im pretty positive that they will fit with no problem at all. Basically I'm looking for some reassurance from someone with a little experience in this field because I'm relatively new at this.

 

This is kind of unrelated, but I have a set of 20X9 Razors with a 24mm offset on my 05 Mustang GT, and there is plenty of room for clearance of the rotors.

I have P255/35 tires and its the same overall diameter as the stock mustang 17's. I would think as long as you run a tire that equates to the same overall diameter as your stock 17's (of course you will have less sidewall) you will be ok. Plenty of room inside the razors.

 

I dont know if this will help but i have 24x9.5 with 30mm offset and the truck is dropped 2/4 and I have no problems.[IMG][/IMG]
