Correcting geometry on low cars....
Especially the steering arms which sit at an awful angle when a Sierra is lowered. Anyone used anything successfully to space them back to a proper angle?
Track rod end extensions, or custom rose joints?
Anything off the shelf for this?

like this?
Just a case of finding some good quality rose joints with the correct thread, some conical misalignment washers, some spacers and a nut and bolt.
would it need the first spacer to taper into the hub like the standard track rod end does? i guess it isn't necessary so long as the spacer has enough surface area at the end in contact with the flat of the hub?

If you move the steering arm down you also need to move the tca down, otherwise you will end up with bump steer.
The 3dr cossie hubs have the connections to the tca and steering arm at a lower point than all other hubs. This was specially done as the 3dr needed it for homologation purposes.

Yeah, that looks like one solution.
Marc, would correcting one arm not help reduce some of the bump steer?
Not sure why putting one arm back to a good position would be a bad thing?

I agree with Marc, you will need to correct both steering and tca. I would weld some new mounting points on the existing hub, switch to 3dr hubs or get some 18"s and highten the car. The sapphs are horrible when lowered as the roll center is far under ground while the center of mass is way up.
The extension showed in the pic above is just making things worse imo as all it does is introduces bending moments where you absolutely dont want it.

So the the steering arm gets longer or shorter at a different point as the suspension compresses and unloads whilst driving which cause steering input on the hub without turning the steering wheel - bump steer.
