Phantom Grip LSD - Toyota Yaris Forums

The Rally cars that have been built where I work use torsen differentials with viscous coupling center differentials. But they are only rated to last 3 runs which is better than the motors which are only designed to last 1 run. Making 950 hp on a 2.1l is rough on drivetrain parts.

Ive seen that problem with rear wheel drive cars that don't have differential coolers. I know corvettes, cobras, and vipers have had issues with overheating the diffs when using a clutch based diff.

I prefer the design of helical gear differentials because their designs can bias torque from one wheel to the other as long as you have traction whereas clutch type diffs tend to just limit the slip so to speak. Guess I just prefer the feel of a gear based diff over a clutch based one.
