Good luck. I hunted all over and finally picked one up from an RL member. Not easy to find since the 3.8 rs guys really don't have much incentive to change it (the guy I bought form when to an even shorter 4.0). I'm excited to install it when I do my 4.0 clutch kit in Jan/February.

The one on carnewell, is that the 4.0 ratio? 3.89 is .2RS right?

3.89 is stock on 997.2 RS. NB is 3.44. I think it really depends on the track as to the benefit. Some shifts points end up in awkward places and some go away.

^ smaart man.

That's true...but I'm not doing it in an attempt to lose seconds (or tenths of a second) on track.. I'm doing it because I've always felt that the gearing (especially 2-4) on these cars feels just a tad long, and that the car would feel snappier and accelerate harder with slightly shorter gearing. I don't mind shifting more and loosing some mpg in 6th on the freeway if I gain some punch in the lower end. 4.0 was too short for what I wanted to do, but I think the 3.89 is going to feel just about perfect for me. I guess I was spoiled after spending 5 years in a modified 996 turbo and I'm looking for just a bit more "push" in the back in a straight line.

Scott - ur doing 4.0 clutch? Not worried about harmonics? I'm going to shark werks mon and debating it...

ScottArizona

Not really. Word on the street is that the 3.6l engines are not as sensitive to the issue. Functionally, if the lwfw set up is good enough for the 997.1 rs then I can't see how it would be a problem for my car (I think the flywheel in the 4.0 kit is about the same as the rs flywheel).

I can tell you that when I switched over to the rs lwfw kit (clutch, pp, flywheels, pulley) in my old 996 gt3, it was the best mod I did to the car...totally transformed the way the thing revved. Definitely worth it...I'm doing it and I don't even need a clutch yet. But I need to wait a few months if I want to stay married!

I got my 4.0 R&P and very happy for both street and track.

Regear the box.

You need to evaluate for your home track to be certain but in most instances it's going to be quicker even with extra shifts

I wanted to do 3.89 or 4.00 in my car and I feel it would absolutely benefit my times at my home track. However, I decided not to do it because of the increased wear and tear on the box due to all the extra shifting. Until more of the newer cars outrun me I'm leaving well enough alone and buying more tires and brakes and seat time.

ScottArizona

The increased wear is the main reason I went with the oem 3.89 (plus, I like the more "middle ground" nature of the 3.89 vs the 4.0 since my car is still mostly a street car)

CRex

The stock 3.89 has little to no wear issue as long as it's properly "placed" at installation. The 4.0, I dunno... I'll be the first to report when I need a new R&P but hopefully not too soon!!

John Chan

The 2nd gear will be replaced before the R&P

Spyerx

Wear issue on 4.0 gearing is because of even rotation and ring/pinion operating on same location during each revolution vs. rotating due to uneven gearing?
