My main goal in my front suspension replacement/upgrades was greater adjustability to be able to have it dialed in "just right", overall appearance and designation as a "Resto-Mod/Pro Street" vibe, and better overall performance.
My focus is quarter mile drag racing performance and cruising on the street, not "corner carving".
I believe it's accurate to say that using the QA1 front suspension components is keeping the factory engineering design, but replacing all of the parts with modern upgrades.
NOTE:
I used ALL QA1 parts in my front suspension replacement including the K-member, EXCEPT FOR a
key component:
The upper control arms (UCAs) are SPC and the reason why is lack of adjustment range with the factory "cam style" UCAs don't allow enough range for my car, and I had 2 different front end alignment techs say so.
@BergmanAutoCraft had a nice in-house tweak to the SPC UCAs that is specific to MOPAR, but SPC also just recently changed the design of their UCAs, which I read about but honestly I don't understand.
I got the SPC UCAs in my 70 Roadrunner from SPC for MOPAR, and they have worked fine so far.
@BergmanAutoCraft
Would you be kind enough to describe the advantages and differences between your SPC UCAs and the "stock SPC UCAs" (if you have any left to sell) and the differences with the new design SPC UCAs for MOPAR please?
