Yeah cheers for the advice. Funny what you say about the greenstuffs, because I too thought they were awesome at first, but now I guess they aren't, or I wouldn't be considering an upgrade. I've done 37k miles and never been on track, so the fluid should be ok, right? Although obviously I would go for new fluid and braided hoses anyway.
Rear discs - yeah but mine are pretty shot, and I'd like to replace them with something that at least looks a bit special. Is there a danger of seriously f**king up the balance of the car by upgrading rear dics etc? I guess not as long as the calipers remain OEM.
