on my 660 im running 28" zillas. in my clutch i had the orange spring, weights, and the 1.5mm shim mod.
when i install my sheave will i still use my shim with your cut or is it going to have enough to turn the tires fine. i didnt know if it was possible to have too much bottom end. i dont run much over 30mph but also dont want it to hit the rev limiter there.

To much shim plus the cut sheave may cause the belt to rub a hole in the cover like my whiterhino cut did. Not sure how much room you got to play with on the 660.

the zillas arent a heavy tire like the xtrs i used to run. i can spin these no problem so from what everyone else has been saying about the great bottom end im thinking i wont need the shim.

I do not run a shim on my JBS sheave. I don't think you'll need it anyway. I've had entire rides where I only used low range for a few tough obstacles.
