Starter Motor problem with aftermarket Flywheel

bezzita

Is there anyone out there heard or has problem with their starter motor with aftermarket flywheel?

In my case.., I am using ACT lightweight flywheel.

My 370z broke down 3 weeks ago.., and the shop found out that the Starter Motor has seized. This is the 2nd time had happened to me for the last 6 month. The shop concluded that the ACT flywheel does not match with OEM starter motor.

At that day.., I can not even push start the car (my car is manual). After reading some article found on google..., I think the problem was: "Starter motor pinion jammed with flywheel gear"..., but the ACT flywheel is designed for 350z/370z!!!!!

My question is WHY the Starter motor pinion jammed with flywheel gear??? What cause the starter motor to seize? or even fail prematurely??

Any idea why???

Is it really because of the flywheel???
