MG MGB Technical - 4 piston caliper setup

Almost done setting my car up with a Volvo/Nissan combination 4 piston calipers/vented rotor assembly that bolts to the MGB upright and hub. Who would be interested in buying a bolt on setup or even parts to complete the setup ie. rotor adapters, dual circuit into single brake lines and T, modified calipers, etc? Just trying to get an idea as to how many people are interested in this kind of thing. Email me and let me know.

I'd be interested in the concept. Is it something that is fairly easy to setup or is there machine work that you are going to be offering. I've been looking at implementing the Volvo calipers on the front with the Volvo master cylinder and rear proprotioning valves to Saab rear calipers for my BGT V8.

The modified calipers clear stock Rostyle rims. Just FYI.

The MGB master works just fine with the volvo calipers at the front. No detectable difference. I bought a volvo conversion set up from a very reputable place "MG Workshops" in Melbourne Australia (run by a nice guy named Andrew) who have been offering a complete volvo/Nissan comversion set up (back as well) for years. Crossdrilled calipers, stainless adaper Hoses, the works. I bought the front (didn't see the point of disks in back)and it cost around $1300 Australian. Less our 10% Tax and multiply by the exchange rate if you need to compare. You would need to tell him the depth of the shoulder on your hub if you were interested as this varies in MG's and the disk adaptor is a tight fit.
PS -Although Volvo calipers clear the rims they don't fit under the flatter style ROSTYLE wheels without a spacer, about 2mm too close, but Minilites and wires are just fine.
I would imagine Jakes spacer is a little thicker than mine and he has machined a few mm off where the bolts attach to the caliper to displace it back a those few mm.

Peter,
You are correct, sir. The adapter is a bit thicker so it places the back face of the rotor farther away from the hub than the stock MGB rotor. This requires a pair of machined shims for each caliper to offset the correct distance and center the Volvo caliper on the Nissan rotor. No wheel spacers required, clears both the rostyle wheels and with a little polising, the OE V8 rims as well. This uses the stock MGB front hoses as well but requires a T and two adapter steel pipes.
