I recently installed a set of BMS spacers 10mm and 12mm for the rear
on my new set of wheels that are - 19X8.5 et 30 and 19X9.5 et 42
these are the same set of spacers that used on old set of wheels
that were the same size but different offset 35 Rear 40

I now hear a flapping sound when I drive but goes away when i apply the brakes. One shop said that sounds like the bolts might be too long and are scraping, causing the flapping noise. Has anyone ever had this problem?
