Did anybody shorten the gears of 2005-06 R53? Is there any kit to do it?

 

helix sells a lowered final drive gear set .

http://www.helix13.com/mini/products/suspension-chasis it is near the bottom of the page.

 

I sent them a request concerning this kit and they have not answered whether this kit fits facelifted R53 or not and what gear ratios it has. On the picture the crown gear counts about 89 teeth. That is corresponding to the teeth number of the facelifted R53. Is this kit is just for convertion of old gearbox to facelifted one? But they write that "It uses straight cut gears so the car is a little louder with that race-car whine". It makes me think that it could be something different.
Has anyone applied this stuff?

Thanks for hints.
I guess I underestimated the cost of metal

It's probably more affordable to look for a facelift box and swap a set of good used crown wheel and pinions over to your box.
