Modified Subframe that adapts the 10” Winters Quick Change differential from RTS into the S14 or 15 subframe. Tested and able to withstand 1200hp worth of abuse, this will be the last rear differential setup you will ever need for your drift or road race S-chassis.

we start with high precision 3d scans of both the subframe and differential to set pinion angle of driveshaft and position of the axles to ensure a correct fit into the chassis. Modification to the floor is required and is fully FormulaD legal.

Now with traction arm brace standard!

differential able to be removed without dropping subframe!

Comes with all new hardware.

raises differential up to highest possible level to protect case and correct axle angles on dropped cars.

please let us know before ordering if you would like the subframe to be non coated, otherwise, we will use Steel-It brand paint for all subframes.
