Not factory but went to Steve@crsperformance Cannock really top notch advise in the end I went with the koni suspension upgrade all around on my 22plate 4M told him what the vehicle was being used for nearly a ton of tools, and towing a 2 ton caravan, so he put together a package to suit, looks in this area of van tweaking was not a preference with me but practicality was,
The difference is a much improved road ride, quieter and all around better handling,
Steve is reassuringly always happy to help with queries, not matter how green they may be…,
