Somehow the question about 6 spds changed to dog ring 4 spds and how some choose to use them. I was hoping (like the OP) to get some more info on high rpm shifting capability, accuracy of gear changes and durability for a 6 spd road race application that uses syncros and is more street capable.

I also prefer to change brake rotors and pads instead of trannies and clutches.

I also have a ZF6 in my c4 corvette track only car and it shifts very nicely but I only use it up to about 6500 rpms. They are just too big to fit in a 70 Mustang trans tunnel, need too much work to adapt and cost a fortune to rebuild.

Anyway - for high rpm use with syncros what works well? I have a POS Richmond 5-spd that needs to go in the trash and want something that works well with a 600 hp 7800 rpm dry sump motor on the road courses. No drag racing is in it's future.
