When I went to install the Neuspeed bar the bar would not go onto the car - the bar and bolt were about 1" from lining up. It took me about an hour of thinking to figure out to jack up the front middle of the car so the strut towers would move out a little. The Neuspeed bar fell into place perfectly. Went to get my camber remeasured and the reading was -2.8 camber. So it definitely did something.
what if you would have done that before installing the cheaper bars. I definately felt less flex which a set of the cheapest ebay sells for my crx. They shouldn't be able to move as once the bar is on the struts can't go inward or outward. Yes there not as nice as the more expensive ones but I can't see how it could make that much of a difference. Both should be better than none.
