I had forgotten about Global West. Wow. They are as expensive as TCP. I know, good stuff. Everone raves about the TCP stuff. Need to be a little conservative with this car. Shop project car. I read that the Ron Morris coil overs can be used with stock A arms. Might try that. Still $850.00
The link you posted to the RM website says $2495, which is much more reasonable for a coilover kit that mounts to the
LCA. I didn't see anything for $850, but I assume you're referencing the kit that mounts in place of the stock shock & spring. I would think it would improve it about the same as the Open Tracker kit, eliminating the binding but that's about all, and $850 is a lot to pay just for that.
The RM design in the link is almost a carbon copy of mine, although I certainly wouldn't claim he stole it from me as we both just used what is readily available design wise to the circle track crowd. (My invoice for them is dated Oct 26, 2004 btw)
I'm using AFCO double adjustable shocks that run $375 a piece. I believe you get what you pay for (99% of the time anyway) and the AFCO shock is just a plain better shock than the QA-1 IMO. From my experience, the folks at AFCO are much easier to deal with if there's a problem also.
The light weight of my design (and presumably the full blown RM coilover kit as well) makes it more responsive than the TCP or GW designs. I weighed a TCP lower arm w/BJ and it came in at 6.8 lb. An older style GW upper w/BJ and spring perch came in at a whopping 12.0 lbs! My upper and lower combined weigh less than that. My upper arm weighs 4.4 w/BJ and the lower is just 4.6 w/BJ.
If budget is the driving factor, I'd just use the Open Tracker stuff. If you can afford the RM ($2495) coilover kit however, I'd say it's worth every penny. I wouldn't consider the TCP or GW coilover kits at any price as they are way too heavy.
