Nah, swap standard springs for CRS lowered recommended and forget the spacers . Comfort and stance (less dramatic drop) ticked. Join the lowered swamper deviantsPretty much the gold standard - Koni Special Active Shocks, std springs, and possibly 25mm lift spacers. Then H&R anti roll bars - hopefully these will reign in any roll with the van going about 90mm higher than it currently is!
I'll have extra weight up top in the form of a roof rack too.
Oh and rear discs and pads. I had a quick look while I had the wheels off today and there's about 5mm of pad left so probably another couple of thousand miles - but I've got three weeks off in late September and will probably do a euro trip of 1500-2000 miles so I'd rather not get down to the metal on the trip!
Just looking at how much space there is between the tyre and the arch liner where it rubbed once - I reckon there's about an inch, maybe 1.5inches. which means I've basically got 1.5inches or less usable travel on the front. Which is why it feels rock hard!
Your van looks great currently with the new wheels
