I was just shopping for 919s for the wifeys trooper RS and found this thread. I have had the 919s on the VX for 1.5 yrs now. I have full extended the suspension more times than I can count (those that have seen my pics no that I "abuse" my VX, and I am on 34s. I get a tiny bit of wheel rub on forward half of wheel well if I brake going down hill on the trails. I did no rear well trimming. There is no problem with the 919s!!! I cranked to torsion bars to level it out, no ball joint flip. Never tore a boot and no alignment problems. It does rake forward a bit, but I daily drive her as well, and have no complaints, hence the search for the 919s on the RS, which will also be a daily driver/trail truck.
