We did a BBK fitment test with some 20" wheels I had on my car (20" Miro M6 reps). Short story: the wheels rubbed against the caliper so we did not install the BBK. We even tried putting on a 5mm, then a 10mm wheel spacer to push the wheel barrels out a bit more in hopes that the slightly larger diameter region of the barrel would prevent the rubbing, but it still rubbed.

What wheels are you aware of that fit on top of 405mm 6-piston Brembo brakes without rubbing? If possible, I'd really like to run 20" or smaller diameter wheels, so if you've got 20" or smaller diameter wheels on your 405mm 6-piston Brembo's, please share your wheel make, model and offsets. Thank you.
