Caliper Bolt thread rate/size?

[ksr-cupra]

Hi can someone help? I'm trying to find out what the thread rate is for the bolts that mount the caliper to the wheel hub? Many thanks

No worries, I only know cause I had to use different length ones recently when making up a 6 pot conversion for the clio. Would have saved me time if it was on here as I wouldnt have had to measure them. So at least its here for next time now

Same here, making up some brackets for some 4 pots. Want to keep the 15in wheel so seeing what I can come up with.

Are you prepared to space the wheel out?

You will be very limited on disk size if you want to keep an unspaced 15" oz f1 original wheel.

They have a big lip around the inside of the rim that really interferes with clearance.

Even with 33mm spacers on mine I could still only get a puny little 300mm disk under and without the spacers I couldnt have gone much more than 280mm

No I have no issues with running spacers if that's want need for the wheel to clear though don't really want to go over 20-25 mm spacer. not even bothered about trying a bigger disc at the mo though just seeing if I can get it all fit up.
​its just a little project I have in my spare time so just a case of trial and error.
