cheers, i was interested in them a while ago. But as they didnt do a 2-piece i tried looking elsewhere but i still cant find any. wouldi have to contact them in OZ to see if they'd do a 2-piece?Russs said:I've been and done a bit of research for you Wullie
They do the 4000 series for the IV, the 294mm discs and the 276 for the RS's with 15" wheels. The 4000 are heat treated etc and as far as you can go with a 1 piece disc.
The 5000's aren't listed for IV's, but I believe they will make them if asked. No extra cost as far as I am aware.
It seems that these brakes are living up to their claims - very even heat disipation and thermal transfer across the disc because of the ventilation design, so extremely warp resistant.
****, that sounded like a sales pitch
