As a performance retailer myself and 1st a consumer ... I always buy direct from the manufacturer or someplace like RalliSportDirect. There is no nonsense that way.Anyway, 1 call to Whiteline them self and POOF, today in the post is a NEW set, a whole new package, not just the 1 bushing.
As an ebay seller. I need to respond within 24 hours to any correspondence or issue. Claims can be opened before 24 hours. WL is a super company an as I would expect. They made you right.
CKE SSP operates in the same way. For this reason, I would never sell my products to a re-seller...
