MFactory is willing to make these final drive gears greater than the current 4.785 they offer.

These 5.1 would be great I tested the 4.785 but I feel I could still benefit from a bigger like the 5.1 on the tracks I run as I bet many of you would do too.

In a 7,500rpm rev limit the car would still push 135mph in 5th gear

And in a VE like me with a 9,000rpm would push 160mph on 5th

What I want say is that the cars will still make good high mph with the short final
and have a killer tranny ratio for the infield.


and if you ask why not make a short gear ratio transmission?
well some Categories like IT-A and Autocross don't allow modification to the gears only the FD.

and a PAR GEAR Set would run $3k and upwards vs these MFactory that its about $580 + s&h.

We need 3 more in order to get this done.
If anyone is interested contact me at neovvl at gmail dot com.

Hello Neovvl;
Could that same supplier be able to make final drive ratios for the GA16DE as they now will have a recalculated weight in ITB and could be weighting about 2290 Lbs making them much more competitive. How many sets(minimum) do they require, and what would the price be???


Thanks,
