For the longest time now I've been considering buying a strut tower bar, but I can't really find any evidence that they really work. Seems to me if one side is gonna lean, all the strut bar is gonna do is make the other side lean as well. I've heard some people say stuff like, 'yea, it kinda corners a little better'.
Is there any real evidence this things really work and that it's not just extra weight? Also, are those $18 eBay strut bars any different from the more expensive ones? Thanks.
