I have 473hp meth feed fpgreen powered 05 mr and other then a clutch (act) which i smoked today racing a gsx600 today my MR 6speed has had no problem. if ur not lauching it all the time it will be fine. I maybe go to the track 2 or 3 times a year. So dont worry about ur 6speed drive it and enjoy it. I have driven a bunch of friends 5speed evo and i love my 6 speed so much better and they alll love the way mine shifts. So im going to be ordering a exedy twin disc this week and will go bak to driving it and enjoying it again

 

05 MR and still going strong! selling it tommorow though :-(
