Best Aftermarket Suspension Set-up

I mean if you’ve got a 73+ disk car and can weld on LCA reinforcing plates and use your factory engine mounts with new poly bushings and your 73+ spindles you’ve saved over $800 vs the list. So that’s $1,700 less overall for manual to manual, and you could knock that entire $800 off a power to power comparison as well, which would make that $1k in savings vs the conversion. And those aren’t options for saving on the coil over conversions.
This right here. 100%
Also to add, I've been daily driving my Duster since 2015. And I have been buying and updating suspension components one bit at a time, something that is easier (and cheaper) to do than the coilovers.
I did the QA1 UCA's in June and the K-member in September of 2016.
I installed bigger torsion bars, welded reinforcement tabs on the LCA's, tie-rod sleeves and ends in 2019.
Installed the sway bar in 2020.
Upgraded the front shocks in 2021 (KYB's with bigger torsion bars and QA1 goodies was just horrible)
The QA1 adjustable strut bars was installed in 2024.
