I'm looking to upgrade the suspension (front / rear) on my Carvelle. It used to be a 9 seater but now only has 2 seats up front, I would say the weight from the old seating arrangement is simular to the roof rack / awning that is now fitted. Inside I have a wooden unit and seating area in the back, quite minimal. So possibly a little more weight than originally along with the centre of gravity would be higher with all the bits on the roof of course.
Spotted that one of the front springs has snapped at the bottom so that needs replacing now.
Not looking to go low or lift it up (would be nice, but feel that introduces a bunch of other issues) so keeping it standard height. I see a lot of springs mention being -30 to -70mm lower, not too sure what this relates to. Would caravelles be lower due to them being 'passenger' vehicles originally?

So do I just replace with standard springs from Brickwerks (https://www.brickwerks.co.uk/t3-parts/s ... -30mm.html" onclick="window.open(this.href);return false;) or Go Westy (no lift) from CVC or something else.
Looking for springs & dampers (Bilstein B6 or B8??) / full kit if possible.
Thanks
Peter
