Upper Control Arms

I will be installing the QA1 UCA's with big balljoint as I upgrade my car from SBP to BBP. Please remind me: I will have 24:1 manual steering with 15x7 wheels and 215/60/15 up front. Would the best caster setting be larger than the Skosh Chart shows when I am looking for a balance of ease of steering & high speed stability?

Yes. So, in keeping with the categories on the SKOSH chart, I would say you can add +2° to the recommendations listed for the caster, keeping everything else the same. For example, “granny” would be -.25° camber, +3.5° caster, 1/16 to 1/8” toe in. “Max perf. street” goes to -.75 to -1° camber, +4.5° to +5.5° caster, etc.

With the QA1’s +5° will probably be about the maximum you can get anyway, although it will depend on your ride height and the alignment specifics on your car.
