The Supra discs are £28.33 each from Brake Parts Online here in the UK. They also show the discs as 82-85 model year. 4 bolt fitting, diameter 258mm & thickness 20mm.
They also have the Vitesse 4 pot calipers at £73 each. So just over £200 for set of calipers & discs, just need those adaptors off Ebay & you have saved yourself one hell of a lot over Rimmers kit price of £405. To be fair to Rimmers though they do include pads, hoses & fittings, all of which you would have to buy separately.
Still, good to know what parts are involved.
