Using the forums search feature,search> H&R Front Swaybar Improves Autocross. I'm not saying that the H&R front sway bar is any better than the SLK front sway bar. But the SLK front sway bar is an improvement over the SRT-6 front sway bar. With less body roll up front,it helps in keeping the rear tires down on pavement during hard cornering. I laid both SRT-6 and SLK front sway bars down together on the floor. Slk was much larger diameter,but the very ends of both bars were the same. Rob,Needswings was checking out the diameter differences on my car with the SLK bar mounted and the SRT-6 bar loose in hand. He could probably tell you if the H&R is really a better bar than the SLK bar. Squirrel Crusher
