If I decide to go multiple piston/fixed caliper, Ron's 285mm 15" wheel version may be my only option, given that the front only AP Racing 15" wheel compatible gravel setup I want is ~$2500 now new, and the 15" wheel useable Wilwood gravel setup is at least $1500.
I need to be able to use 15" wheels due to working those gravel rallies, as a 16" tire with
enough sidewall (a 50, or even a 55 series profile just ain't gonna cut it!
) to get down the stage roads without blowing out on impacts, and/or cracking the 16" wheel just
will not fit under these cars.
