Brake Caliper Clearance

Am looking at custom wheels and would like to check the front brake caliper clearance.

Has anyone measured up or have a template?

It will depend on how much lip i can get., this is the rim profile im looking at.

If i had my car would measure, its still stuck in germany!

What size/offset? Any dimensions of the drawing? I made a cardboard cutout of the caliper to check on the 8.5" rims but I doubt you'll have issues.

Here's how i modeled the caliper on some cardboard, should give you an idea if it'll fit.
The dot is the center of the hub/wheel, caliper sticks out around 1.75" from the face of the rotor.
The cutout around the dot on the left was 66.6mm wide so it fits inside the wheel.
You should have no trouble clearing a +10 9.5" wheel.

This is useful - thanks. Whats the hub face to rotor dimension? Based on that its looking ok. Im assmuming 30mm from rotor face to hub face.

If you put that in wheel rotor face would be against wheel hub face? Do you have caliper width?

Don't have any dimensions, the caliper shape might look weird but that's the shape that was needed to clear it when i made a negative of the cardboard.
