.73 ratio 5th gear
What was the fifth drive and driven gear tooth count in the t5's that had the .73 5th gear ratio?

Re: .73 ratio 5th gear
Depends on your rear end gear ratio. It's outlined in a sticky on this thread, here's the link for convenience.

Re: .73 ratio 5th gear
Depends on which T5.
The headset gears of the mandrive and countershaft can change fifth tooth counts and the mainshaft changes which driven gear, so there were multiple fifth driven / drive sets that can make 0.73.
Call Hanlon Motorsports, give your service tag. Say you'd like to buy 5th drive / driven to go 0.73 ratio 5th.
