E30 Zone

I have seen a pair of Porsche boxster rear brake calipers fitted to a compact and wondered if anybody has fitted any to an e30?
they are a 4 pot brembo caliper and look like they will fit under certain 15" wheels and 16" wheels.

That looks good, I might see about getting a pair for the front and some adapters made first. That looks like a rally car to me, what are you running on the front?
