Building my triangulated 4 link
One thing I will say is that at least in my case there was not big range of movement of the rearend up and down. I talked to Morison about it and they said that was relatively normal due to the design and the short bars.
A relatively short range of travel is one of the main drawbacks to a triangulated 4 link. It’s also why the design, angle and length of the links is really important, it’s not hard to build a triangulated 4 link that has binding after only a very short suspension travel.
Like everything suspension related it’s a trade off. On an A-body, getting everything to fit without moving stock the fuel tank or altering the rear floor and back seat involves compromises that do effect how adjustable the triangulated 4 link is and how much travel it can offer.
For road racing, a 3 link is generally preferable, it’s more adjustable and doesn’t typically limit the travel as much. But again, fitting a 3 link design into an A-body is problematic unless you start moving stuff around. Which is why the A-body kits are all triangulated 4 links, because you can get it to fit with a stock fuel tank, tailpipes, etc.
Qa1 has that 6 link rear suspension that bolts in, it’s even more limiting for travel. But it bolts in. All about compromise and what’s important to you.
