Some pics of the BMS 10mm front and rear spacers. No issues with clearance or drivability. I have to say, I can't see 15mm fitting on the rear which is what BMS says fits. I got to the 10+10 by doing my own measuring.
As promised, some pics. Video/Sound clips to follow. Shiraz and Jeremy were around when I collected. Sound is very exotic and refined. Going to change in character in the next 500km by most accounts.
