Hello all, I took my 2018 Cupra 300 hatch in for 4 wheel alignment today and the guys at the garage couldn't get the rears fully aligned as the concentric bolt that sits in the lower part of the swing arm (that holds the springs) appears to have failed. The spacer (behind the nut) that is meant to turn with the bolt isn't moving (assuming the little notch has broke that fits into the groove on the bolt). Does anyone know the part number for these bolts? Anyone had this issue before and do you have to go to Seat to get the parts? Any help much appreciated, photos of both sides of the swing arm below.
