Ok I’m spitting in the wind here, but I had my H&R ARBs fitted about 3 months after the B14s as it was still rolling more than I liked, and I found absolutely no difference whatsoever. I even went under the van to see if THQ had really fitted them.
Take what you want from that, everyone else thinks they’re wonderful, but I can’t help thinking that maybe there’s an element of “emperors new clothes” and I regret wasting £500 getting them.
They made an enormous difference to my van.
Do you know which setting you have? IMHO they need to be set to their stiffest F&R.
