GTO gearing is a no-go. I'm told that the gearing is all the same, it's the mainshaft gearing that moves everything to a higher ratio. Don't really want that. I think I'm going to get the .80 setup and try it. Won't have time to do it before NOLA, and won't need 5th at Hallet (much), so I guess it will remain untested until TWS.

Only other option is this company, which has cut gears for a .83 ratio, but it's a thousand bucks. 2.66 1.78 1.30 1.00 .83 .70

It's tempting, as 6th would actually be useable if I ever went to a track bigger than TWS, and ran out of 5th gear. Not too far off from where 5th is now.

Thoughts?

Sorry to hijack your thread, I hope the new transmission you picked up will work out.
