Porsche calipers on the front?

[AdamGardner]

Hi I have been looking into weather porsche boxster/911 rear calipers will fit the front of an e30 with 15 inch team dynamics motorsports wheels.
I have seen this done on e36 cars but never an e30
Otherwise what brake set ups are people using for 4 pot track day/race cars
Thanks Adam

Someone on here was selling a setup like that using discs off a new mini a while ago, I thought about buying them but he said I would need spacers to fit them under my 16" wheels. I think wilwood do a set that fits under 15's
