hi i have tomei crank with os giken flywheel clutch combo in my gtir recently the had failure of the flywheel bolt shearing off. on dismantly found that the bolt are bigger than normal gtir bolt's and the thread is courser.m12 with 1.25 thread pitch they are 30mm long from head to end on thread.the shank of the bolt is longer than the normal gtir bolt so where the flywheel has been sitting it has worn the shank down ie shank 11.40mm thread is 12mm anyone else had this problem.

thank's zia

hello mate. yeah found out that previous tuner used rb26 flywheel bolt's cut down to 25mm but these and the fact they overbored the flywheel caused the failure. thank's have seen the bolt's listed but was unable to find dealer who could get them as carn,t seem get in touch with tomei by email?any link you can give me would be great.

thank's zia
