Aristo/Lexus/Soarer GS7 DCT kit

This transmission kit will take your JZ powered Aristo, Lexus or Soarer to the next level. It may also be possible to use in Chaser, please contact us for confirmation prior to purchase.

Lightning quick shift changes at 50ms, and a gear ratio to keep you in the “sweet spot” for torque and power at all times.

The kit is to be used with a Getrag 7 Speed DCT gearbox to the BMW F8X M3/M3/M4 (equipped with the S55 engine) It is one extremely rigid transmission, with cars now running over 1500nm without failures.

The stock clutch inside the gearbox can hold power levels up to 1000nm.

Other upgrades from Dodson available.

The gearbox ratios suit both the auto and manual diff very well, and the gears are closer together than the V160 with a longer 7 gear making cruising on the highway even better.

The supplied billet output flange enables you to choose between a stock Supra turbo auto driveshaft, or a Custom driveshaft with 1350u-joint.

Saving you money on your custom driveshaft, or gives you the possibility to upgrade on a later stage.

The 1350 solution is also great for owners that are converting the naturally aspirated Supra and dont have the turbo shaft avaliable.

Our output flange comes with the correct pilot hole (for both Toyota and 1350) to perfectly centre your driveshaft.

The flywheels come with pressed heavy duty starter ring gear, so no need to use your old flex plate for the starter.
