Would not have thought so as they are a great tuning aid and the moulded parts seem to come in one setup only.
I know some of the USA guys are running the LAW36/LAW37 brackets with the inserts reversed to give the same width increase as the LA271 mouldings but still have the ability to tune the geometry.
Ahh that explains why I could see them on Tebo's car and much better for the wallet too!
