The R came stock with the "Super Performance" brakes, 380 mm front and 376 mm rear.
The base V6 came with the "Performance" brakes, 355 mm front and 326 mm rear.
Both the V6S and base could be optioned with the Super Performance brakes.
My V6S came with the stock brakes ie 326 mm rear but a few years ago I updated those rear brakes to the 376 mm version.
So if you have a V6S or V6 R-Dynamic the VAP rotors will "work" for the front brakes only but not for the rear brakes unless the car was optioned with the Super Performance brakes or the optional 376 mm rear brakes were fitted later, and AFAIK I am the only one here who has done that.
You can't just whack the 326 mm calipers and pads on 376 mm rotors, they look pretty much identical to the 376 mm versions but they are slightly different and they won't fit.
Seeing as the V6S and base both came stock with the 326 mm rear brakes there is a bigger market for the smaller two piece rotors than you may have thought.
