The ride height on my 1.5 is about 0.75" lower on one side which Tesla diagnosed as a blown rear shock. Rob at Dietschwerks too a look and noticed the springs and shocks didn't match left vs right. On one side the shock is labeled Tesla 6000012 and F4-BE3-E071-T0 which seems to be normal for the Roadster. The other side is labeled F4-BE3-E071-T1 (no Tesla markings). The spring on the other side is labeled A126D0037H which seems to be normal. The spring on one side is labeled B126D0060H which seems to be something different. Does anyone know what the B126D0060H spring is?
