WHT Z06: Gear Ratio calculator

WHT Z06:
Gear Ratio calculator

Here is a cgi I wrote to do gear ratio calculations. You can use it to try out different rear end gears and tire sizes. Note that there are two ways of entering the tire size. Be sure to check the radio box next to the method you want to use.

This table shows the specs for WHT Z06 which has the Borg Warner T56 six speed manual transmission (RPO MM6) and 3.42 gears (RPO GU6):
