So I hear all over the place that the new RS is going to have different gear ratios. So im looking all over the net for the info and I can't find it any where. So does any one know what the ratio's are gonna be? and what the speed in each gear will be relative to a non RS ?

Actually...All ratios are same except 6th. The final drive is where the difference is: 3.89 vs 3.44

2010 GT3RS / 2010 GT3 / 2008 GT3RS

Gear Ratio
1st gear 3.82 3.82 3.82
2nd gear 2.26 2.26 2.26
3rd gear 1.64 1.64 1.64
4th gear 1.29 1.29 1.29
5th gear 1.06 1.06 1.06
6th gear 0.88 0.92 0.92
Reverse 2.86 2.86 2.86

Final Drive Ratio 3.89 3.44 3.44

"As in previous years, the only available transmission is a 6 speed manual. Compared to the 2010 GT3,the final drive ratio is shorter (3.89vs.3.44) as is 6th gear (0.88vs. 0.92). This lower gearing in conjunction with the more powerful motor results in superior drive dynamics, especially in a track environment. For additional high speed engine response, a lighter single-mass flywheel is employed."

Results:

0-62 MPH 4.0/4.1/4.2
0-99 MPH 8.1/8.2/8.7

Top Speed 193/194/193 (2010 RS rev limit increased by 100 rpm)

You are welcome

 

Which makes me wonder why bolting a Cup short final ratio axle is not more popular in the US.

 

It exaktly was it is

A cup use a 8/31 and a street car a 9/32

 

No thank you. Now what is the part number for the 3.89 ring and pinion.

This would be a fantastic upgrade to my 2004. A good compromise over the 4.11 cup gear.

 

A Cup use a 31/8 and thats a 3,89

 

SMR... do you still have your GT2?... noticed you were looking for Cup Car chassis!

 

No i sold it, im building a 997 turbo RSR now

 

Well done, good to see it when complete... good chat going on here... https://www.6speedonline.com/forums/...our-turbo.html

 

The cup is a 32/4. It wears faster than the 31/8 because the gears mesh with the same teeth every time, rather than rotating around.

So the important question- anyone found a part number on this sucker yet??
