Hi fellow E36 non M owners, I've just installed front big disc conversion and rear disc with Nano pads..i have to say they are at least 50% stronger then stock! Plus i retain my stock calipers..I've told my friend/retailer that if its really that good, I dun mind writing up for him. :top: Hmm, in my own layman terms, the front disc is a 320mm, which comes wif the dog-bone plus disc is thicker then OEM..the rear is the OEM size, 280mm and the vanes inbetween the front ventilation is thicker for more strength...The slots, which are curved makes no noise in operations and still serve the purposes of being slotted...Truely wonderful! I got them with the Nano pads, which are something like 600degree pads with very low brake dust..hmm, after 2 days of driving around, i virtually haven't seen brake dust on my rims. Anyhow, since hes based in Singapore, heres hes name and contact if u guys ever happen to want better brakes(as good as my friend's OEM M3 front) but wanna spend justa fraction of the price..
