Tubular control arms vs rebushing

I've been doing it for years. And yes I've plotted the entire curves from full droop to full compression.
Until you've been on a track and watching wear patterns - and better yet measuring tire temperatures, that's when camber and caster needs can get dialed in for a particular tire on a particular combination. Run the car ride height low (both front and rear) to be in the better part of the camber curve, and lower the static center of gravity, and the static roll axis....

Good to hear that you're investing time in fine tuning what works best. How low are you able to go? What alignment specs are you typically running on the track?
