November last year I had WA Suspension install Tein coil overs in my VEII SS. Last month there was some groaning and sqeaking coming from the RH front corner, particularly with some lock on. Happened to be in Perth on a Friday morning so called past, no dramas from them, straight into the workshop for new top bearings both sides and a wheel alignment. No cost. Yeah its under warranty but to fix it on the spot was cool.
