I'm thinking about getting a set of RPF1s when I get Hoosiers for the track and selling my TE37s. I know from zee stickie that convex 17x8.5 +40 RPF1s clear and flat/concave 17x9 +45 do not.

Will 17x9 +35 RPF1s clear StopTech calipers?
Will 17x9 +45 clear with a 5mm spacer?


TNX!

Turns out I already had the answer.
I dug out my old conversation w/ Enkei from a few years back when I was considering RPF1 for street wheels (I went with PF01).
Apparently the issue with RPF1 and StopTech brakes on the FD is radial clearance. The 17x9+ wide wheels have a lower dropped center that interferes.
17x8.5 is the widest 17" RPF1 that clears StopTechs on the FD.

 

My 17x10 rpf1s clear according to the template, +38 offset. There is a member who has stoptechs on his FD with the same wheels as well.
