This is my primary test bed for Zilla motor controllers, because of that it needs to be pretty powerful.
The transaxle and driveshafts are from a Porsche 930 (Turbo Carerra) since the stock one broke quickly. It has a LSD and I run the motors backwards to avoid flipping the ring gear. I leave it in 3rd gear and no longer have a shifter or clutch pedal. Reverse and Series/Parallel shifting of the motors is performed with SW202A contactors (three sets) controlled by the Hairball.
