Welcome aboard!


Take some time to make a plan for the car.
300 ft/lbs torque is max on our clutches.


What is your goal for the car? What is your budget?
Then we can make some recommendations.


Read a bit. There are quite a few discussions on this topic.

350 ft/lbs is closer to the safe number of torque on the stock clutches

Just get a EVO X turbo swap tune it and if slipping is an issue. Dial down boost.
Make sure to get a trans cooler, heat allows clutches to slip more.

The numbers max supported torque really depends on the dyno calibration and type they were using.
