With all the different clutching methods I just wanted to throw this out there before I install my 1mm shim.

I mostly ride trails 10 to 40 mph and looking for a little more low end grunt so I’m going with the 1mm shim as I am staying with stock tires.

After some more reading some suggested when you shim it’s best to change out the secondary spring to keep it in low longer and prevent belt slip.

I see that most people who use 1.5mm shims use the purple spring but with a 1mm shim would the purple spring be too aggressive with the stock tires?

For those that have experience with this, should I just leave the stock spring or change it out to the orange or purple one.

Thanks for your advice!
