I agree 100% with Pete....that FMS balancer is a POS! I went through one in less than a week,do yourself a favor and buy a real one that is SFI rated. Stock style balancers are only rated up to 4200rpms.......that's a far cry away from where most of us shift. Also,engine torque can "spin" the balancer ring off the elastometer (believe me,been there)
I run the Pioneer SFI race one.....it's made of billet steel,no spacers are needed,direct bolt on for sn-95's,and it's coated. Price from summit with like $180 or so.
