I just bought a parts car that has a WS-6 suspension. Its a '91 formula, that has been pretty much gutted. But they missed the good parts. Rims, sway bars, steering box, springs. I plan on swapping all this stuff out. My question is about the lower control arms. Me and a friend are going to make my SFCs and a STB. I am wanting to make the lower control arms also. A nice adjustable set. I have seen these with heim joints on both ends, without bushings. Does anyone have any experience with these, and is the ride to harsh for a daily driver? Should I just buy a set of poly bushings and build them with them. We will duplicate the spohn design to an extent. We will also make a panhard bar, and various other pieces, eventually.

They're not too unbearable, it depends on what you can tolerate and what your roads are like. I thought they were going to be worse, but mine isn't a daily driver.
