ok, what exactly is this? And, can anyone confirm if VT Series II Calais definitly had it?
I'm pretty sure they did, and I know when I got my VT II Calais, the first thing I noticed different from my old VS Calais is that the VT was MUCH more stable on the road .. low body roll and very stable/firm in handling ..

However, for the last while .. probably almost 6 months, it seems worse .. i now scrape on every bump/curb, and a corner i used to be able to take at 60+ easily, now hits the skirt on that side on the road if I try now ..

Now i've just been assuming something's gone in suspension somewhere and needs replacing .. but, had the fuse box open the other day, and noticed .. no relay or fuse in the "Self Levelling" spots .. Yet i'm sure the calais is supposed to have it. Interestingly, it seems the problems with handling/suspension seemed to arise aroudn when I had my ABS module replaced by Holden ~6 months ago .. Wondering if they forgot to put back a set of fuse/relay ..

Would this cause tehse symptoms? A car equipped with SLS, but without the fuse/relay installed?

Any ideas? Thanks guys!
