t-5 upgrade options

Well, I've done it again, 3rd tranny is now dead. This last one had some upgrade bits from g-force, but obviously not enough.

I'm thinking about doing G-forces dogtooth conversion, anyone have any experience with it or other options? Does TKO offer a dogtooth option? The car is almost exclusivly used on the track, I'm not worried about noise or problems driving it to work.

Thanks for any input!

Heres the previous failure, I expect about the same this time though I haven't pulled it yet to inspect.

After a bunch or reading I think I'll do g-force's dog ring kit w/ the road race ratio.
