The kit has been around for years and users have had good results when they have employed it. I think you would too.

A new shift finger and pads greatly help. The carbon fiber blocking rings are a nicety and not really a necessity. There have been angle issues with the cf rings as there have been production runs where the angle of the ring doesn't match the angle of the gear cone and they wear prematurely.
The biggest issue with the TKO is the production tolerances on the gear cone surface finish. When the synchro can't make friction it's hard for the components to match rpms for a quick shift. The biggest part of the sure shift upgrade is the correction of those surface finishes.
These transmissions also really benefit from an aftermarket shifter and a nice breakin period.
