I have a set of F66 2025 JCW Wheel take offs I want to fit to my F56 JCW. Given the change to the brakes on the new 2025 JCW, they appear to need spacers to work. Anyone tried this or have an idea how much of a spacer might be required? Any insight would be appreciated!
Yep. Did that - can't figure out how many MM I need and was trying to learn from someone who may have done it. Hate to buy spacers that don't work :-) or are more than I need.
Mount the OEM wheels. Measure the clearance from the brake disc to the back of the wheel spokes, both at the outer edge of the rotor and down near the hub. The, remove the OEM wheel, and remove the brake caliper and tie it out of the way. Then, mount the new wheels and measure the clearance from the brake disc to the back of the wheel spokes, both at the outer edge of the rotor and down near the hub. Compare the two sets of measurements, and see how much spacer you need to get the same clearance for the new wheels.
this may seem like a sledgehammer to crack a nut, but it’s far easier to rotate your wheels with 2 pins, so I have 2 already
Make sure you have clean wheels 1st….
“ other brands are available “
POWERALIGN WHEEL MOUNTING GUIDE PIN
PF99-514-125
Use guide pins and a stack of fat washers “ as spacers” you’ll will need at least a pair,
add one wheel bolt with same quantity of fat washers to oppose the guide pins ( the fiddly bit)
hang wheel, nip in 2 other bolts, to ensure its sat square, and no gaps in washers.
check calliper clearance (say one washer ) spin wheel checking for movement
then measure once on the hub, and secondly washer stack
as final sanitary check, count each set of washers.
buy spacer,….relax
