Before uprating any rear springs due to a 'dragging' bottom' I'd advise getting the Cali weighed on a weighbridge with full travel mode items onboard, including driver and passengers. Check front axle, total load and rear axle.08 Cali now on 70 K mls. When first bought, at 60 K mls, found the rear dipped so much over speed humps that the towbar bottomed & scraped. Got B6s fitted together with Graystone's rubber insert spring assisters in the original springs.
Now 10K later, pre MOT inspection reveals broken spring & disrupted spring mounts. All being replaced by trusted main dealer here in Exeter. Requested T32 springs but not allowed to fit as nonstandard.
The conversion to higher spec shocks plus inserts produced a wonderfully transformed controlled tight rear end. But suspect that the inserts restricted spring deflection so much that huge pressures were transferred to the spring mounts. Leads me to cease recommending this type of spring assister which has done sterling long term duty on 3 prior estates. But these ain't going back on the Cali!!!
Reason for this is simply to see if you are overloading any specific axle. If an axle is overloaded then unload the excess weight, check ride height and if too low then consider a spring change.
Spring upgrades do not increase the load capacity unless an expensive reclassification process by the DVSA is completed. Insurance would also need informing.
