Rattle at 2-3k rpm only when Cornering!!!! Help

Hey Phil had a look at my starter tonight and the heat shield is really loose but looks like its rivited on or something? Thing if would be ok to remove the shield all together? Or would the heat from the manifold melt the starter wires?
 
Jup, the earlier clios have the plate fixed with rivets.

The manifold produces a very big amount of heat which would probably damage the wires.
I will take a look at it later too! Maybe there's a much simpler solution to it than buying the oem brace.
