. Take note that the adjustment of spring rate which the kit allows should be checked after say 5000 miles from original fit as main springs will have settled. You should have two C spanners in toolkit. Unlock the two lock rings with these then using one spanner to hold top of threaded part adjust lower ring. You are aiming to provide zero clearance with static suspension between stub axle and rebound spring but such that spring can still be turned by hand. Repeat for other side. Adding a weight to simulate driver/passenger may help. Note that finding the static position of stub axle may vary so double check before tightening the upper to lower lock rings each side.
FWIW SSL recommend making this adjustment with shocks removed and letting car bounce off a trolley jack to find the ideal static ride height.
