On your rear brakes (or any brake-related components - ABS pump, etc) - yes.

Rest of the car? Nope.

Why do you need rear discs? I doubt you race the car or drive many hilly roads in Iowa...

No the only reason why I want it is for when I go lapping next year I don't want brake fadding.

You would be much, much better off finding something decent for the front brakes.

They're set up to be quiet and stop the car ONCE from a high speed. They're absolute junk for repetitive use - I can fade mine within 5 switchbacks on a twisty road.

Seriously? Nothing is easier to work on than a disc brake, and stopping power is the main reason why drums were abandoned on the front of cars long, long ago... cars today actually HAVE stopping power, while cars with front drum brakes just slow down. Gradually.

Yeah, my Bug would NOT stop in any kinda hurry, especially down a hill.

Yes - apparently some 2011-2012 1.4T Automatic Cruzen and now about 136,000 BMWs. BMW just announce a recall for loss of power assist braking at low speed. I don't know if the BMW problem is related or not other than being in the same situations - low speed with "smaller" motors.

Turbos.

No vacuum pressure @ high idle due to boost.
