901/915 Custom-Built Race Transmissions
To win races, you must match your gearbox to both your car and the track.
Porsche produced many different
gearsets
for the 901 and 915 transmissions
with this in mind. We have all the Factory ratios, and also have specialty
ratios to truly dial you in.
We have torque-biasing and ZF-type (clutch pack)
limited-slip differentials
ready to install.
We custom-build
transmissions
to meet any specification from autocross to Daytona.
