Pro Tour guys. What tires r u runnin?
My '74 Duster
18x9's with 275/35/18 BFG KDW2's up front
18x10's with 295/35/18 BFG KDW2's out back
The BFG KDW2's were discontinued shortly after I bought these, not sure what the next set of tires will be. Up front the 18x9's have a 6.4" backspace or +35mm offset, but I run them with DoctorDiff 13" cobra style brakes which add about 5/16" to the track so the effective backspace is more like 6.1" In the back I have a '68-70 B-body 8 3/4, so the 18x10's are +38mm or a 7" backspace. That's also with a DoctorDiff 1/2" spring offset and about another 1/2" trimmed off the quarter lips for clearance.
