Hi guys. Just getting round to fitting Brembo M4s on my RR-6. I've noticed that when removing the original spacers there is a little tolerance when fitting the calipers - i.e. - when I hand tighten the bolts you can move the caliper back and forward with your hand. It's maybe less than a millimetre but brakes aren't something you want to take chances with. Is there a set of shims or anything available to sit inside the caliper mounting holes to make up the difference and centre the calipers?
No is the simple answer, the tolerances are super tight! even more so when running Brembo T Drives due to the fact there over another 1 mm thicker, the only corrrect way to centralise the callipers once you have removed spacer and dowel is applying the brake whilst tightening the bolts, be sure to keep the pressure applied and you should be ok.
