Brake Disc - DIMMENSIONS

[sax-puma]

I'm putting on the Focus ST170 discs, does anyone know if these are thicker than the standard puma discs? If so, how much thicker?

Problem being is that I don't have much thread left on the studs as it is, what with the 17's and the 3mm spacers.

You should be fine, but only just.

can anyone tell me the width of puma front discs? i believe the st170 discs are 24mm in width but correct me if i'm wrong.
just that my 17's have an offset of 38 and ive got 3mm spacers on to help prevent rubbing on full lock. dunno whether i will still need the spacers???

238mm ones up to 2000 = 20mm

That is the friction / contact area though, I believe he is asking about the mating area, i.e. thickness at the centre bore.
