I did it a few years ago to one of my 87 Syncros with otherwise stock
brakes all around.
It doesn't increase the braking capacity in any way, it just makes it
FEEL better with less pedal pressure needed for the same amount of braking.

I have some concern that the reduced foot pressure needed to apply heavy
braking could make overheating the stock brakes more likely.
The lighter foot pressure could deceive the driver into thinking they
aren't stressing the brake system as much as they really are.

I have a couple more of the BMW boosters but I'm not anxious to install
them in my other vans with stock brakes. With larger vented discs up
front I'd be more inclined to do it.
