I once had boge turbo gas suspension kit in a mk1 vw jetta which came with a boge set of lowering springs. I absolutely loved the way the car handled, on rails and loads of grip even with standard 14 inch average tyres yet compliant over bumpy back roads, and I would like to get a set for my 99 cordoba vario tdi. The problem is that I'm having trouble finding a seller or sourcing kits or springs of this nature. Does anyone know where I could bag a set of these springs or whether like bilstein they maybe use eibachs springs. It did have boge printed on the springs but I concede that this still could have been a eibach spring with boge printed on it. Thanks for any help.
