First of all:

17.1.4.D.5.c.1 Any anti-roll bar(s), traction bar(s), panhard rod or watts linkage may be added or substituted, provided its/their installation serves no other purpose.

And:

GCR Glossary
Traction Bar - A link to an axle housing or hub carrier which resists torque reaction from the wheel by acting in compression or tension.


And now the question:

Can I replace my factory rear toe links (lateral links) with an aftermarket heim joint equipped "traction bar"? By the letter of the rules, the toe link could be described as a "traction bar" according to the GCR glossary. What do you think?
