If you replace your belt there are some things you should consider.
If your new belt is wider, shims can be used to compensate for this difference. That's why I disclose 2.5mm of shim with the Dayco XTX, some to off-set the belt thickness and some to change the final drive ratio. As the belt wears thinner I remove shim thickness, less belt = less shim.
My new belt was longer, I am experimenting with OD weighting for additional drive to full speed.
I'm just playing with the set-up. I can always use the OEM belt. BTW, race teams run each new belt to determine optimum performance for each during a race. I will end up with two set-ups using diff. part combos.
