Seeing that all b series trannies dont have the greatest syncs in them, does anyone know of a company that makes some aftermarket ones? I dont think there is... kaaz?
just bought an ITR tranny and want to preserve it as long as possible.

 

To preserve your tranny you should use the lightest clutch disc possible. 80% of synchro/tranny wear is from spinning up or slowing down the clutch disc.

I've seen synchros beat and rendered usesless from just a couple passes in all motor race cars.
