Max Diameter To Fit Inside A 17" Wheel????

[BBShark]

I am looking at putting either 13" or 13.5" inch rotors on my car. The caliper adds another 1" to the radius. So this means the inside diameter of the rim will have to be 15"dia. for the 13" rotor or 15.5"dia. for the 13.5" rotor.

I would like to run 17" wheels. Does anyone know if I will have clearance with either of these rotors?

Right now I am only concerned about caliper clearance on the diameter. I understand that there may be issues with caliper clearance to the "spokes".

I have personnaly installed Wilwood 6 piston calipers on a 14'' rotor using a 17'' Torque Thrust 11 wheel. You have to do your homework. You need to figure where the caliper mounts in relation to the mounting flange on the spindle for the wheel and this will give you the rotor's hat dimension.

Wow, a 14" rotor on a 17" wheel? Maybe I won't have problems after all. The KORE3 website has an 8.33r (16.66 dia) for caliper clearance with a 14" rotor.

It can depend a lot on the wheel and of course the caliper (number of pistons, etc). It can vary. With some wheels a 17" might work and with other wheels you might need 19". Usually brakes plus 4" is pretty safe, but not always perfect. Make sure you get accurate information and calculate as returning rims is not always possible. Also keep in mind that under hard loading the wheel will have some deflection so you want some extra clearance (or might be able to grind if you find it makes contact). If you go tight be sure it beat on it hard, and then check the calipers for contact marks.
