extended lower ball joint/roll center adjuster
Re: extended lower ball joint/roll center adjuster
Your post lacks information. What car are we talking about? What does your current setup look like?
These things are becoming pretty ubiquitous on GEH/DWB chassis. Most of the guys I talk to outside of this forum that are tracking their cars are running them now.
Macstrut and S2000 folks have different applications and different reasons for running them, so it's hard to make a blanket statement.
Proper FWD touring cars have adjustable geometry and adjusting roll center is a mega adjustment that can change the entire setup methodology if used correctly. Expect to be able to soften the car up significantly since you'll have more natural roll stiffness. FWD cars in general are really sensitive to roll axis orientation, I think you will do more harm than good if you raise the front without raising the rear as well.

Re: extended lower ball joint/roll center adjuster
I don't have any direct experience with the roll center adjuster since I don't really build & track my own stuff anymore. When the Honed rear kit came out I definitely had a moment of yelling "finally!" to myself for someone making a rear adjustment available. It's fundamentally a good change, it also gets your dampers back into a more neutral range of stroke at the height you're at.
I'd do the whole geo kit at the same time (front/rear roll center adjusters and tie rods) and add some caster if you can.
The good news... none of this should affect your bushing project and you can totally do them separately.

Re: extended lower ball joint/roll center adjuster
If its your first track day, keep everything as is and learn your car and drive on the track as is. No need to go all out on mods for your first time out there. A good set of pads along with maintenance items, and you should be good to go.
Re: extended lower ball joint/roll center adjuster
^^ Also this.
I'd argue that replacing old bushings is a maintenance item, so for sure do that if you can/want. Then learn the car as is before you start making geo and setup changes. Then you will be better able to understand how/what those changes have done to the car, or at least what you need to go back on if they don't work for you.
