@ Bill - I have a receipt in front of me of the Rothsport upgrade and you might be able to help me with what this might be (who it compares to the values of your table):
95030290121 1st Gear mainshaft assembly w/splined 2nd
G50 2.25 2nd Gear set
G50 1.579 3rd Gear set
G50 1.2826 4th Gear set
G50 1.083 5th Gear set
6th gear is the "old" 5th gear.

Bill - thanks for data and the chart. The charts confirm my impression of more torque at lower RPM. If you have not driven a car with this gearbox it is very difficult ti understand the performance improvement.

Uh....yeah. Especially when having to do a 50 mile all freeway run at 4am for an ER computer repair at one of my businesses, a 24/7 answering service where..............let's say time was of the essence.

I have the perception I'm getting better mileage in 6th so I use it on the highway sometimes. Also, since my RS shifter still rattles I use 6th as it is much quieter rattling in 6th for some reason.

One more fan of the short box. Moving 5th to 6th , keeping 1st and 2nd, and adding new 3rd, 4th, and 5th gears (equates to adding an additional gear between 2nd and 5th on a stock box) makes the car just more fun to drive. It is amazing the difference when you shift to 3rd and you are in the sweet spot for revs, then again for 4th, then again for 5th, and then you had better be on the track!
