Gemballa says they limit torque to 704 pound feet to preserve the PDK gearbox. So, seems Gemballa currently does not have the capability to upgrade the box. The exhaust is also customized to fit the new rear bumper. Additionally, no performance numbers or dynos support the horsepower claim as is typical of European tuners who live off their name.
The changes beyond the exterior are of course the over the top body kit which is traditional Gemballa. The taillights are changes as well as LED's added to the front bumper. The interior also gets a complete overhaul with stitched Alcantara everywhere.
Only 30 of these will be built which at a $333,000 conversion price does not bother us one bit.
