Front lower chassis brace.

Has anyone fitted one of these between the castor mounts? I used to be a fabricator welder, so I could make one. But do they make much difference?

No, but I found the ARB stiffeners made the handling poorer so I removed them. Granted this is further back but may have a similar effect. I have a strut brace in the engine bay and that helps.

I made some of those ARB stiffeners years ago, but took them off because they seem to stop the ARB working properly. I made a stronger strut brace too. People have gone to a lot of effort to fabricate castor mount braces, I just wonder if it's worth it when the front cross member bolts across the shell close by.

What would this achieve? Like you say the front of the control arm is secured in the cross member so would this just prevent changes to castor angle on heavy cornering? Don't think the cup cars had this, and they did have a top strut brace which was semi-removable, the brackets were welded to the strut towers (which were slightly reinforced) with a bar bolted to the bracket, very similar to what BMW does with some of their road going cars like the X3.

I have seen pictures of a later Cup car that had the lower chassis brace. Supposedly it's purpose is to reinforce the rear control arm mounting. This is what Lindsey sell now, but I doubt they make it themselves.

The LR brace looks a lot less susceptible to being ripped off on a bumpy road than the first one posted - you'd want longer bolts for the caster mounts too as those holes are notorious for stripping at the best of times

I could probably replicate what Lindsey are selling, out of 2" mild steel flat bar. Would it be worth the effort though.
