The picture looks like cis pistons not the 102mm 964 RSR pistons, the 964 RS used the same 100mm p/c as all the other 964s

here is what the 102s should look like




look for tapered wrist pins, coated skirts and the big valve pockets

964 versions and 993 versions are not interchangeable

These are heavy enough so the lighter tapered wrist pins are desirable, they also bump the cr a bit. Over all they work well w/ lumpier than stock cams
