Have the Raceseng CasCam - Caster + Camber Plates on our BRZ for the last four years and everything was fine until I moved the car after it was sitting for a few weeks (prior to that it was at the track). Rest of the suspension is stock.
In the short drive there is a very loud metallic bang coming from the top of the right front suspension whenever the right tire went over any uneven pavement. Doing quick aggressive left-right to load up the suspension does not duplicate the issue.
Looked underneath, can clearly see that the spring perch is making contact to the underside of the strut tower.
Any thoughts on what failed or what else I can check?
