what size disc can i go up to? i have nissan gtr r33 brembos on the front , of whitch i bought from rata2ie from here but the discs are warn and warped so need to replace. just onedered what sizes i can use so to vary my search for some new ones.

Warped discs is a misnomer, many disc manufacturer have details on their sites about this, the issue is caused by pad imprint which causes highs and lows on the face of the disc, when discs are skimmed in theory they are taken off a minute amount of metal, it is mainly pad imprinted material, Google it, there is plenty on it and just may be more cost effective to have them "cleaned up"

i bought this set of brembos second hand from rata2ie and they came with used disc and pads although they seem to have good amoubt of pad left and the discs seem to have a few hair line crakes or faultlines in them, but i bought them because i was after the calipers, so i just used them but as soon as i used them under norm fast rd use i noticed a slight wobble under high norm braking. ive drove no more than 500 hunderd miles on them and today after a spirited motor way drive have noteted that i wouldnt be right to push then. only to find out eight hours later i wanted to drive home and have now a warpie disc wear sound under even light use.so now need to stop noise. so new disc or new pads?
