I talked to Phil Hindley of Tech-9 Motorsport as part of the recent air-cooled RS documentary that I made. Here is what Phil says that his company did/does to the 993 RS to make it a better track car. Oh, and how he hit the limiter in sixth while driving on the autobahn to deliver a 993 RS to a customer at a Spa trackday!

Tremendous video...thanks for sharing it!

Hitting the limiter in 6th was on a car with the lower 8:32 crown ring and pinion set. I drove a 993 RS CS with that fitted, it was a bit too frantic on the road. I didn't redline it, the mathematicians will be on it already, but I doubt it would go much above 130mph?
I much prefer the G50/32 set up.

I can't comment on that, you would have to check with Phil Hindley at Tech 9

P906

in 6th gear (0,82:1) it is 157mph (252kmh) at 6900rpm with the transmission G64/31 (993RS)

more like 152 when you use the actual loaded revolutions per mile instead of the unmounted tire OD

This is for a 265/35 x18 and also +/-2 due to tire specific variations

I've got a Cup /30 trans in mine, top is ~163 w/ 265/35 x18 & 6800, wouldn't want something any shorter even for track days unless the rev limit was raised considerably

While the stock RS suspension is really nice for serious track use you would want full RSR, which is still surprisingly streetable

Just for clarification, I think you may be confusing engine and gearbox types?

993 RS Engine type; M64/20
993 RS Gearbox type;
Basic M002 = G50/31
Clubsport M003 = G50/32

If you don't have it already, the 993 RS technical specifications bulletin is detailed and well worth getting hold of.
