Oohh that's what I would go for..

Just remember to make sure that the offset for the disc and caliper is correct as the compbrake one might be different from the alfa one!

Yep, I did on my car. Just the bit that goes from the caliper to the bracket on the suspension. May be you could persaude the old one to fit, but I didn't try.

Yeah, I thought the same think about the two part discs Suba sugested. If the offset is right, then I think they would be a better option, and probavly lighter too.

That said, I've been very pleased with my 3g's

I'n definately getting two piece discs but Paul at Racepads has offered to get them made for me so i assume they will be Brembo items.
