I generally recommend rear LCAs since I'm a little picky about alignment.

Thanks! Myles basically just answered the same question via email, I just didn't have the patience so I made a post

I don't mean to de-rail this thread, but could you give me your thoughts on bump/steer roll-center correction? I've been considering various bushing correction kits as I'm on tein flex Z coilovers, running 1.7" drop (-2.6 camber all around). Interested in gaining some steering weight back, as well as return-to-center.

Derail away! I'm interested in the bump steer kit myself. Not sure it's worthwhile between 0-1" of lowering, but who knows I may go lower than 1"

Prior to coilovers I did have 1" lowering springs on stock struts. I can confirm that the steering still felt similar to stock weight, and the ability of the steering wheel to return to center after a turn felt nice. After coilovers, I almost have to 'guide' the steering wheel back to straight, presumably due to the drop.

I'm a research kind of guy, and I don't mind researching the correction (caster?) methods for this, but thought i'd ask here first.

Unfortunately, I'm not knowledgeable enough nor do I have any experience with the kits so I don't really know and am just parroting what others have said about it. Maybe more knowledgeable people can talk about it?

It sounds like you lost caster. Did you have that checked? I wasn't aware caster is reduced with a drop. Anyone?

I've just had a motorsports shop align the car twice (steering wheel was off-center after first alignment for some reason). I've got the alignment specs... Will post when I get home.
