Having just fixed my rear-heavy T6 campervan with new rear springs, I want to lift the front just 15-20mm without changing the front springs. I can find a "coil strut spacer" fix for just about any vehicle I can think of, but can find NOTHING on Google for the VW T6. Does anyone know of a supplier? Or can tell me I'm searching for the wrong words? Or can suggest dimensions so I can make something up from scratch? Thanks, Tim.
