Does anyone know a company that makes traction bars for the EM/ES chassis?

 

you mean like traction bars on an old muscle car that mounted to the leaf springs to prevent wheel hop?

 

A set of good drag coils with stiff bound settings should be more than sufficient.

The LCA is triangulated already.... what do you need them for?
Spring the car right, tie the strut towers together and put the hammer down.
Its a strut suspension... there's no real active movement going on, the wheel stays right where it is.
