disc thickness specs for MK2 GT3?

[johnfm]

I have a MK1 with MK2 disc upgrade. My workshop manual only has specs for MK1 discs. Anyone have the MK2 disc thickness to hand. Need new disc and minimum thickness data.



Cheers

I saw that. I thought that was for the MK1 disc that run with the 4 pot calipers. Either way, mine are toast as they are a shade under 32mm thich, which I think is a touch beyond their useful life more MK1 or MK2!!

This article mentions 34mm thick discs as part of the 2003 GT3 spec:

When I used to get covered in brake dust we recommended a change after 1mm lost per side.

2mm was the absolute max and I have seen shattered discs from people running beyond 2mm.

I'd go for 1mm per side on a GT3.
