i had them on the st the fronts lasted for 5000 miles and wore the inside edges out but had quite a bit of camber on it lowered by about 90mm on coilies lol and the outside edges on the rears are worn out but the insides are ok and there was a lot of camber on there to as lowered a similar height i blamed it on two roundabouts i used to abuse a lot for the outside edges and general hard cornering
