This is an update on the brake set up I am using. Here are pictures of the stuff mounted and the calipers with the adapter. If any one is still interested I would sell the adapters made of 7075 aluminum with the holes taped and you have to supply the caliper ( part # 120-6806 124.95 from summit racing) and the rotors from racingbrake.com for a G60 corrado which is 180mmx22mm and there is some modification to the center of the rotors which need to be opened up by 1 mm to fit over the BMW hub and there is an edge of the BMW hub that needs to be chamfered to allow the wheel to bottom on the new rotors and the hub surface otherwise the rotor is loose on the hub and the wheel wont tighten onto the hub. The brake lines are avalaible from IE for 20.00 each. If you dont like this idea its you life but If you do I will be selling the adapters fro 100.00 shipped.
