difference between 944 '86 turbo & 87 turbo+ brakes?

If you use even the softest Porsche spring I think it would still be too heavy as the motor is in the front for that car. Also, you'd have to use the Porsche top mount for the spring and I don't know if the VW bearing will work with that or even if the spring itself will fit into the VW body. I've never looked into using the Porsche springs, mostly due to my first sentence here.
