Geometry changes with DSE LCAs

[streetk14]

Hey guys. This has got to be my first post here in close to a decade. Sold all my first gens, and got away from older project cars for a while. Anyway, I picked up a 68 Firebird from a long time friend last fall, and have been working on making it a nice driver. Now to my question:

The car has Global West upper control arms with del a lum bushings. These have been on the car since probably 2004. The current lower control arms are stock with poly bushings. I’m looking to upgrade to a set of tubular LCAs, but am trying to figure out my best option. It’s really between DSE and Global West. The plan is to just run a standard coil spring.

So from a geometry standpoint, is there a problem going with DSE? It seems their lower arms add additional caster, but is that it? Will I have problems using the GW upper with DSE lower? Anyone know how much caster the DSE lowers add?

Thanks guys. Feels good to be back.
