Greg is definitely a good guy, and always a source of reliable information and good products.
Back in 2007 he installed his suspension lift on my 2005 X. In those days it was Total Chaos upper control arms, Radflo shocks in the front with Eibach coilovers, and a 2-leaf Deaver add-on in the back. We kept the OR version Bilstein rear shocks that had been given to me by another SCCX member. I think this was one of the first installations (not the first, of course, but there weren't all that many out there yet), and Greg installed it for me personally, working in his driveway in Riverside. He aligned the front end right there, using a tape measure and crescent wrench. That alignment stayed perfect for the rest of the time I owned the truck (traded it September of 2014) . . . and I did smack the front end of that truck around a bit.
