Dave, its not just a bigger bar but the way it is mounted. The standard 1 inch bar I had, was mounted with rubber bushings. The 1 1/4 bar I have now is mounted in an aluminum sleeve with heim joints at the control arm. The difference in rate is more than 25% maybe 100% or more. When I changed bars, I went from 500 pound rear springs to 800 pound rears to balance the car. I actually needed to add more rear rate but decided to take some bar out of the front. The bar is mounted at an arm length of 13.75 currently. The wheel rates all the way around in roll are in the 375 pound area, which is stiff. The bar is hollow and splined. It is .25 wall. The length is 34 inches and the arms can be attached at 12.5 inches to 15.5 inches, 4 different mounting points in between. I am definately useing more of the front tires now that it is stiffer. Before, my front end just rolled over and never really worked correctly. I hope this helps. Scott
