Hi, if anyone knows the answers to the followng questions it would be appreciated.

What is the 6th gear ratio of the manual gearbox? Brake disc rotor size and width of the R3's 19 inch rims? Thanks

 

19x8
4.78 for the Manual (and 4.3 for the Auto. Both 6sp).
Rotors are 12.7 in front and 11.9 in the rear.

 

Thanks Natey, but I should have been clearer is 6th in the manual a 0.70 overdrive top gear ratio? Must be a tall gear to help with CAFE I would think.

 

RX8club.com should have the answers you need. Great bunch of guys over there too.

 

Here is the info for both RX-8 manuals:

Gear.......S1............S2

1st........3.760........3.815
2nd.......2.269........2.260
3rd........1.645........1.640
4th........1.187........1.259
5th........1.000........1.000
6th........0.843........0.787
REV.......3.564........3.603
Diff F-D..4.444........4.777

 

Thx so much! Must admit I stopped buying new car magazines regularly after the FD RX-7 was dropped. Kind of missed out on the RX-8 era, lol.
