This also reduces your RPM drop from 3rd to 4th, will now be 1,448rpm, and a drop of only 1,249 from 4th to 5th. Way more sporty in the high gears now. Just my suggestion.

OK, I'm liking this idea and think it is the best approach.

Now Does anyone have or have a source for a QQ (25/25) or a SN. I think this would be a (28/23) ...same as a (39/32) ...right?

For that matter would a (26/26) as from an SC Gearbox be the same as a (25/25)?

Thanks all.
I think this made a good thread on the subject.

Cheers,
Jay
