OEM oversize pistons

While flipping through my Bentley manual for an entirely different reason, I
noticed that Audi DOES offer oversize pistons that meet the SCCA's 1995 Solo
II rule specs for stock-class cars.  That said, most aftermarket pistons are
available only in .5mm oversizes and if you use these, I'm not sure that you
can achieve the proper piston-to-cylinder wall clearance for a race-oriented
motor within the limits of a .020" overbore ... of course, this doesn't mean
anything to me: my '85 4000s needed a 1mm overbore to clean up the cylinders
and therefore is no longer legal in H-Stock.  Oh, well...
