I'm research different clutch/flywheel setups and I've came across something rather interesting that maybe someone can help me with.

For the 07 TL-s, we've got one flywheel part number and the stock tooth count is proclaimed to be 123 teeth. I just got off the phone with spec and just last week they had a TL-s in that had an OEM clutch/flywheel with 126 teeth.

I was doing some searching on Azine and some members have even reported having 125 teeth:

Spec has two different part numbers for their flywheels, one with 123 teeth and the other with 126 teeth. The only way to count the teeth is to pull the flywheel. My question is, how is it that with one OEM part number we've got multiple differences in flywheel tooth count?

Thanks.
