For an in-depth discussion about it's track use, thicknesses, etc... I'd suggest just typing "Evolution Motorsport" or "watts-link" into the search function at http://corner-carvers.com/forums/index.php

The discussions have been ongoing over there, and are quite detailed if you can wade through some of the other "stuff". I've responded there in great detail. Also, if you check the EVM site, you can download the article from Mustang Enthusiast Magazine where they quoted me on the characteristics of the watts on track.

Short answer, it's plenty strong, works great, and increases rear grip to the point that a different driving style is required from the old "stab and steer" technique.
