heard a massive TWANG from the NSF last night driving home. get it into work today to discover the NSF coil spring has snapped

working for a motor factors i assumed a lowering spring kit from our spring suppliers would be nice and cheap... but it was cheaper from GSF by 15 quid!
anyways, anyone had any experience with the GSF 40mm lowering kits? they will be fitted to BOGE turbo shocks.
