Got the Spohn control arms installed this weekend! The full install only took 2ish hours. While it was all apart I also installed some new parking brake shoes as the old ones were seriously smoked. So Far I'm happy with the controls arms, Spohn calls for 75ft/lbs of torque for the intall but I've noticed a bit of clunking on accel, and a bit when pulling in to steep parkign lots. I have about 250 miles on them so far and will probably retorque them closer to 100ft/lbs later and see if that remediates some of the noise.
