I am also installing adjustable sway bars, but first let me preface this.
I've had race cars, and swore that my next would be a street car. Combine that with the fact that when I'm at the track, I don't want to work on my car. I also don't want to drive a race car suspension to the track. Adjustable sway bars can solve that. More specifically, dual bar adjustments will solve that.
I looked all over the internet for a splined sway bar end with an adjustable blade. Saw CAD models, but not anything real and able to be bought. Tarett and Rennline make beautiful billet aluminum pieces for the Porsche platform, but nothing I could adapt. Believe me I tried!
With no other option, I bought the barrels that are supposed to be welded directly to the sway bar, as well as the blades (spec'd to my car) and started cutting stuff up.
I cut off the spline end after making the barrel at the angle I needed:
I then used 1/4" steel to build the front, back, and sides. I put a big bevel on the arm side that took a root and 2 cover passes. I beveled the barrel side and welded all front and back:
Once everything was welded up (took forever so as not to distort the barrel), I started grinding and filing. Here's a few pics almost done, had to weld up a few pockets that bugged me. The radius is all weld!
Installed them to double check tire clearance and verify I got the angle right:
I have lever/cable actuators to adjust each blade individually.
I can also connect the bell cranks on the blades to feedback linear actuators. I can move them with an H bridge driver. I could then run trim pots on the wheel and adjust the sway bar and receive position on my dash. Probably won't go that way, but is an option.
