Message I think those ratios look really neat, with those ratios I would be lest tempted to shift into 2nd when breaking into slower turns at the road course. Using 3rd to power out of turns and being able to stay in that gear a bit longer and then using 4th for most of the rest (obviously using 5th on the longer straights).

That's a lot of shifting.

My questions are is it REALLY stronger (any type of gaurentee against breaking?) how much does it weigh, how close are dimensions (exhaust interference), and is it any less efficient (drivetrain losses)?

Have you ever seen an empirical efficiency datapoint constant for any transmission, ever?

My 4th gear grind is pretty bad and I would be looking seriously at this option in the future esp if you could get the price to more along to line of 3250-3750 using a carbon type clutch disk and a carbon fiber DS. Then is it comparable to my current proposed (and extremely pricey) drivetrain upgrade path.

97 spec transmission ~1700
RPS carbon carbin ~2000 -OR- Fly wheel and max series ~900
pst carbon fiber driveshaft ~750 ([ [ www.pstds.com ] ])
3350 - 4450

Utilizing a carbon type clutch disc material and the PST carbon fiber driveshaft would add alot of value, IMO.

otherwise the plan is used Jspec transmissions and replace as they go. Not much fun...

How exactly do you plan on blowing up multiple J-Spec transmissions?

Recursively Yours,
