I like the lift and I like the springs. The progressiveness and whiteline bars control body roll well. I'd prefer a quicker rack and pinion but in general it's a good upgrade for Malaysia plantation runs or in case your SLS is gone as a replacement for the SLS. I have replaced the struts with normal KRB struts - nothing special. It's a touch more bumpy than stock but certainly a lot cheaper than the $2000 I was expecting for an SLS repair. I did try the 30 mm lowered King Springs on the front with the standard rear springs and KYB (no SLS) but the back is just too soft. Take note than KS have a standard replacement spring for the back on the SLS that brings it back up to standard height with standard KYB struts as well and you retain the standard front struts and springs.
