Well I seriously don't know, but this seriously sounds like another thread like the strut tower brace one. Some people say it doesn't do anything and say it's useless, some say it is of defnite help and aid in some way. Under extreme conditions, I can definitely understand how it has some aid, but then again it's just a thought. I for one have heard people say that they experienced wheel hop under hard take-offs much more frequently when they took them off however. So it could really go either way. But under "normally-driven" circumstances, I say they are of no true benfits worth measuring.
