Tony: I was just about to forward this URL to you
OP: As the post above mentions it's really about what you are trying to accomplish. The Sportlines will have higher rates and they will be lower (and IIRC linear but Tony can correct me if I'm wrong). I would not suggest OEM dampers with the Sportlines but you could get away for the OEM dampers for awhile with the Pro Kit.
IIRC Peking had pics of his car with both in his thread so check that out too.
