Hi all. After a fast review I need a new clutch set. Planing to upgrade to a basquet and plates from 999r (aluminium) instead of oem 748 (steel), change bolts to titanium and pushrod. But i´m not sure if i have to change my drum to 999r one (need one new anyway). Do I order my oem (748 y2000) or the one for 999r? May an afther market alloy drum does the job? I´ll thanks any help. TIA.
