Lucky you, a 4motion Caravelle Join, The Select Few,

I have no idea what the pound rate of the springs or length. I would suggest having a word with
@CRS Performance Performance he can provide better springs and more importantly better Dampers. He is a KONI specialist. The original fit springs and dampers are not great KONI adjustable dampers are. Have a mind what you would like to do with your Caravelle 4Motion it is quite capable off road has very good rut capability just long ramp over but still more than enough to get to most farmstead’s and camping fields with sensible tyres even in the worst conditions. In any case a set of KONI and springs would make a starling improvement to handling and ride of your steed and I very much doubt that you would regret it. He is the man, he can answer any of your specific questions related to suspension.
