Yeah, you need Excel installed.. It's just a handy sheet that works out gear speeds, mph at whatever rpm in whatever gear etc .. What's your tyre size?

The data got distorted in the paste so be careful how you read it.
Sixth should read left to right  'blank, 0.725, blank, 0.725'

This I think was posted in the library by markiii.

Goto http://tire-size-conversion.com/tire-size-calculator/ and get your tyre circumference in inches from your tyre size

How to work it out using c60 and 245/40/17's (77.6 inchs circumference) as example is:

(6th gear x final drive x mph x 1056) / tyre circumference = rpm
(0.725 x 4.529 x 62 x 1056) / 77.6 = 2770 rpm
