A= 22mm
B= 50mm
C= 27,5mm

Any idea if these will fit..... or how I can make them fit.... he wants 100 quid for them...

To be honest, they're not worth bothering with, they are the same thickness as the standard discs, and very likely to be almost the same diameter. Braking force will remain the same.

Its the thickness that's the main issue in my opinion. There is less material for the heat dissipate in to.

I've never had much issues with the standard brakes accept they just don't have good stamina. I would be very concerned on using them heavily for track use.

I have the 30mm thick S14/Z32 discs on mine, just need to make up my prop to get the car on the road to test things out.

After ironing issues out with the car, I will very likely be upgrading the brakes to M3 discs (315mmx30mm).

But back on topic a little, would be interesting to know whether or not the S13 discs used on the front of the S12 hub would result in the correct offset of the disc though...

i tied a z32 disc up to the s12 set up and it made the disc in the wrong place in the caliper, it was a long way out.

I'll probably get them anyway... as the discs on the car now have seen better days.
As for performance of the standard discs.. I am not too dissappointed, I run castrol SRF and pagid carbon metallic pads and was outbraking virtually everything on the track last weekend..... not better than the best, but nobody passed me under braking.
However, if I used left foot braking all the way around the long long long corner going out onto the straight, I had the pedal going really low at the end of the straight.
Nothing beats bigger brakes.... but as I'll need new discs sooner or later I'll give these a whirl and see how it goes.
