Alterkation question. .....

I’d prefer the lighter aluminum PST steering box that also happens to be less expensive.

And the taller Howe upper ball joints for increased camber gain would have similar advantage to an Alterkion front suspension.

I don’t think the tubular LCA’s are a big gainer over stock in many situations.
I think the big gain is frame clearance for really low cars and if you have to pay someone a lot to weld sway bar brackets on non-sway bar LCA’s.

so there’s an additional $476 off.

I'm not even running tall Howe ball joints, mine are the stock height because I already run FMJ spindles (from junk yard, and the A-body ones would work fine) Or hell, knock another $175 off the total for new ones from DoctorDiff (with shipping). The only gain for the QA1 LCA's is suspension travel IMO, and the new ones actually require some modification for that to be true. Mine are the old style before they added the lower bump stop into the design. I had a reinforced set before the QA1's and they worked great, I just wanted the additional travel because of my ride height. Puts it back on par with the stock amount of travel.
