Inboard Rear Disc Brakes - Plausibility

[yetibone]

The only production based cars I know of that use inboard brakes were Jaguar XKE, XJ6, and XJS. Mabye others within that marque as well.

Replacing the rear rotors on those is no fun at all. Most labor guides say it's a 10 to 12 hour job.

I believe the benefit of lower unsprung weight is outweighed by the complexity, inability to shed heat, and difficulty to service.

Also, in a VW, you may also have to use shorter axles.
