Can a cabby be made more rigid?

Need technical Q/A then you're in the right place

hi All,

Did anyone try to make their convertibles more rigid
with an x-brace bar and did it work.
many thanks.

There should be a bar underneath on the cab.
I have a strut brace and have noticed a difference, also in an M30'd cab.
Hardtop helps too.

Where should this bar be exactly?

Back behind an M20, but now I can hear it better.

On the 2 chassis rails.
Looks like an "S" shape

Thanks Rav/Brian - I'll check mine is there when I next get her up in the air. Dont remember seeing it when I last spent some time underneath her.

thank you all for the input.

I'll go for the strut brace first.
Is there any particular strut brace make, which will do the job best?

many thanks,
Peter.

The S shaped bar is bolted at the front of the heatshield by the gearbox and effectivly holds the shield up. It's stronger than it looks.
