Note - It is assumed the installer of these products is both qualified and competent. Warranty does NOT extend to installations that do not have appropriate bump stops installed (spring protection).
Note - Bump stops shall provide minimum seat height protection to 210mm (compressed) - Generally Topaz OE (Track) bump stops to not provide suitable protection and led to reduced spring/ride height; this results in excessive camber and accelerated tyre wear (cupping/scrubbing inside edges)
