1973 3.0CSA 4HP22, 3 Webers, AC, 4 Bilstein HD, stock springs cut a little, street driven only, no track ever, don't want progressive/lowered springs, geezer-driven daily....needs heavier sway bars. What's the wisdom? Thanks. A.
I have a 23mm E12 sway bar in the front and it fit easily.
I have Hardy & Beck lowering springs and their specially valved Bilstein shocks. All suspension rubber was replaced with BMW OEM parts at the same time.
H&B recommended the E12 bar. They contend overly stiff bars put too much force in the flexi E9 body.
My rear was 18mm stock.
I like the combination very much.
I can confirm that the ST # 52015 set do fit the E9 chassis. I just bought the front 25mm and rear 22 mm bar hardware sets for my car that had the bars already. Their website does not list them for an E9. The front anchor pieces have a square tube attached that must be removed,and you might have to lower the front sub-assembly to get it to fit on the frame. My urethane bushings needed to be replaced. I don't think those anchor bushings are made in rubber.suspension techniques bars. 52015 set (for the e12). this is the set i have always heard fits our cars and is what Carl Nelson uses. please verify before buying ... or order from Carl.

You mean the sub-frame, holding the engine(!) and the suspension (!)...oh boy....I can confirm that the ST # 52015 set do fit the E9 chassis.

Do you know exactly what these “specially valved Bilstein shocks” are? How are they different from stock e9s?I have Hardy & Beck lowering springs and their specially valved Bilstein shocks. All suspension rubber was replaced with BMW OEM parts at the same time.
It’s not a big deal to drop for the install, maybe 1/2” is enough. Easily done with a standard trolly jack. The subframe fasteners aren’t fully removed, just loosened a bit,You mean the sub-frame, holding the engine(!) and the suspension (!)...oh boy....
Forgive my ignorance but does a strut tower brace perform the same function? If so, a lot easier to put on for added stiffness and actually nice to look at.
