He's talking about bouncing. Different than scraping. You need to roll your fenders. I had the same issue with my FR500's and 315 Nittos. Rolled the fenders and no more rubbing.Had a similar sounding issue on my '01 and it drove me crazy until realized it was the tires hitting the fender liner at the lip of the fender whenever I wend over a decent bump. It was a high pitched scraping sound. Between being lowered and running pretty wide wheels/tires on the rear, there's really no fix without going to a skinner setup or making the car higher again. Not sure this is the case on yours, but I would make sure before you put extra money into new shocks.
So the thought is now the reason the rear bounces so much is because the spring rate for SRA springs is lower than IRS...so the car is bouncing on the light springs.
When I hit a bump I hear scraping, I'm not sure if it's the car bottoming out of the bump stops hitting.
They are Eibach 3510, should be a 1" drop.

He posted that afterwards. If you read the original post it only mentions bouncing.Looks like he's talking about scraping to me.
