Ernie,

I must have missed this tread when you first posted, glad it popped back up to the top.

I have a few questions:

The TKO 600 RR that you installed, does that have the same ratios as the gearbox listed in the ERA FIA manual? Does the RR designation refer to the 0.82 OD unit?

TREMEC 600

1st, 2nd, 3rd, 4th , 5th
2.87, 1.89, 1.28, 1:1, 0.82:1

What rear axle ratio are you running? 3.54 or 3.31 or ???

Compared to the close ratio with that high first gear ratio that you had, how do you like the setup you are running now?

Thanks!
