Sound like you put the shims in. That was what drove me nuts. Trinity messed up on the measurements and they added shims. The shims are more than required. Leave them out. However when that happens the diffs will leak on the out drives. Smart Trinity smart.
In another genius move they left out the SG Nut kit that should be included in every kit. Don't cut the Collari! the reflex isn't worth it. Other SG Nuts won't work because whoever designed the clutch used 2 different size bearings and with the nut kit they include a reduction bearing with the friggen nut.
job is because of the job costing by Trinity is cost us time and patience. I had to wait almost 2 months to get my reflex going.
Even now I am waiting on parts from distributors that Trinity says are in stock and available. My LHS is pissed at the fact that online shops have the stock, and he can't get it.
I will sell my Reflex if I continue to have the parts stream problem. I have a Yokomo that I don't have this kind of grief.
