Appreciate it! what about bushings?

That is what me pointing out "with sphericals" meant.

Did you buy those with the arms like that or press them yourself with OEM parts?

he got them pre-installed since it was cheap back then. I got mine bushings only and it was cake to install.

Can confirm, a cheap harbor freight press and tossing the bearings in the freezer makes it an absolute breeze.

Are you guys getting a brake squeal at times accelerating out of corners when not touching the brake and VSC all the way off? I don't know if it's just the PMU 999's partially rubbing the rotors, vsc still jumping in a little or something much more concerning like the diff I need to worry about.

Yes, only on certain tracks and pads. If they start wearing uneven, they can move at the bottom side toward the hub and just slightly touch the rotor with high G load and cause that sound. Test it by moving a pad pair to the other side of the car. That is how I figured it out.

Been through 3 sets of 999s and they only squeak, when braking and over heated.

Has anyone installed the full suspension Verkline kit?

If so, was it effective in eliminating sway among the higher power application and on bumpy tracks?

I have yet done it for my Supra but i replaced the front castor arm bushing with a set of Millway spherical bushings on my F20 1 series and it made a very noticeable difference in braking stability and steering feel.

I think on top of the front castor bushings, rear toe and traction arms you could probably add the rear solid subframe bushings as they should add some level of feedback from the rear.

I'm running Ferodo DS1.11's and they squeal when they're significantly past their optimal operating temp. The day I was at Buttonwillow recently, it was well over 103F... You can hear them squealing for a short time even when I've let off the brakes before hitting apex and accelerating.
