Trackday on Sat using slicks and RS42s on AP 4 pots, good day - except the nuts wouldn't come off at the end - ended up with sheared bolts - I've got the caliper and disc off and have removed the studs, anyone know where I can get some more very very quickly and also is there an upgraded version?

This happens due to overtightening so make sure when you get new tyres etc they are careful as new studs and nuts costs a lot (especially on the rears)
