Hi guys I put dobinson comfort medium duty leafs in the rear and bilstein 5100 shocks and only got about 20mm lift is that normal, and up front I put the bilstein 5100 set on the middle setting and got 50mm with the stock coil. I want to keep the front at that height and try to raise the back up another 30 to 40mm,it has only got a canopy so I don't really want to go a heavier spring if I can get away with it as it rides superb with this set up, so has any one got any ideas what I could do to raise the rear.
