I recently updated the **** of unsprung weight links and decided to share it with a variety of forums. Feel free to keep, chuck, yell at, or do whatever you want with it. I figured since it took so long to gather all these **** links, it might be worthwhile sharing. Hopefully this won't offend anyone. Its just an **** of available information for those interested in investigating it.

Basically this is an collaboration of urls arguing against plus sizing. Since the argument is frequent and rather heated, I've been collecting these urls for quite some time.

very interesting. Some of it has good points made on both sides (non performance cars being better off with smaller, less easily damaged wheels for one) but some of it is just plain F.U.D.** Like the CNN article. Obviously they never grabbed a scale, or read a spec sheet. But metal is always heavier than plastic or rubber materials isn't it? [Roll Eyes] What a moron. (many of his other points were fine, but that crap bugs the **** out of me. I call it lazy journalism). ** Fear Uncertainty Doubt (coined in reference to IBM's predatory fear mongering about other platforms in the 80's)
