Looking at Tubular K member
Here’s the list I created for the AlterK to fully rebuilt stock comparison. I explained my reasoning for what I included, basically the goal was to make the two systems as comparable as possible
Alterkation or K1?
That being said, there are things on that list that fall into the “nice to have” vs “needed” category. It just depends on the planned use of the car and your own skill level. Like boxing the factory LCA’s will save over $400 right out of the gate, but only if you do the rebuild and boxing yourself. Or QA1 UCA’s which would save a little bit and still be more than capable of getting the needed alignment specs.
BergmanAutocraft also has a complete kit now -

Which as kits go is a lot more useful than the Hotchkis TVS as it includes important stuff like the torsion bars and shocks, which the TVS does not. It also includes the newer and much more expensive SPC Gen II UCA’s, which IMO would be overkill for most applications. Not saying they aren’t better, just saying for a car used primarily on the street I would put the extra $400 somewhere else. Like toward a new steering box. But it’s a great choice as a one stop shop and Peter might even let you substitute a couple things, I dunno.
And the torsion bar set up can be put together a piece at a time, unlike any of the coilover conversions. The only issue is that if you’re not careful with your parts selection/installation installments you may end up needing to do multiple alignments. Which could add to the cost if you’re not doing your own alignments.
