OK thanks guys for all the help. Now for some more questions.

Ok it looks like Im going to go with a 5 lug conversion on my car now as a last minute decision.

Right now Im running 4 lug cobra replicas with a rear size of a 17x10 with a 275 40 tire. If I go with Prostars, should I go with 15x10 or 15x8 and what would be the correct backspace? Also what size tire would be the best?

For converting the front, Ive heard that the lincoln mark 5's (or whatever they are) front rotors will work on the fox. Is this true? Im going to be running a 15x3 1/5 on the front.

My cobras will be up for sale with all tires plus 2 extra tires so if anyone is interested before I put them up let me know.

Thanks for the help.
