Clearance between face of caliper and back of wheel

[ghunt81]

How much clearance do you need to have between the face of a caliper and the back side of the wheel?

I'm working on this Brembo swap with the S550 wheels I bought- turned out to be more of a headache than I anticipated. With 3/8" spacers I have right about 1/8" of clearance between the back of the wheel and the closest part of the caliper (which is a very small area, right at the edge of the caliper body closest to the hub). Is that enough?

.01 inch? Lol

This was asked about strut to wheel clearance once and someone said credit card thickness.
Not sure if that'll carry weight on this too, but if the calipers body stays rigid compared to the hub/wheel I can't see why not

A credit card width.

If your wheel flexes more than that, you've got bigger issues than caliper clearance.

Wow, no more than a credit card? I saw various answers all over the net, but I since Brembos are fixed calipers I wasn't sure how that data applied. OK, so I should be good with what I have.
