    Another sway bar question

    Ok Im running H&R race springs with billie sports, UUC camber plates, a cabrio 21mm front sway bar and an IE 19mm rear bar. As you may have read in other posts by me I am having a problem with excessive oversteer in my car. I cant even come close to the potential of the cars limit in a corner without kicking the ass end out both on entry and exit. From what I have read the car should be pretty well balanced with my setup. Ok some my front bar in proportion to the rear bar is kind of small. I was thinking about maybe going to a larger front bar but I am confused. If I go to a stiffer front bar I would assume that would give me more front end grip and and add to my oversteer problem. The only thing I could think is it may reduce body roll in the front and balance the body roll front to rear a little better. I am confused

    And now you know why most people run little or no rear bar. ;)

    I've got a UUC set (22/19) myself, but I'm on stock springs. If I were you I'd try adjusting the rear bar to be less effective first as that's the easiest thing to do. From there, start getting rid of rear sway.

      Sure it's not technique related?

        No, I have quite a bit of racing experience, I did 2 seasons in a shifter kart and a ton of other bits and bods. I have tried many different driving styles and am convinced its the car. If you load the chassis in a corner the rear gives out way before the front. I am quite comfortable driving a tail happy car but I feel the car would be faster and more consistent with a bit more balance.

            You have too much rear bar.
            I'd remove the rear bar completely, but if you want to keep it, adjust it to full soft.

              I have a stock front sway bar and an Eibach 16mm rear bar set at full stiff, I like it a lot.

                First adjust it to be less effective.

                If that's not enough, try removing one of the endlinks to see how you like it.

                  That suspension combination is going to result in the car being a bit tail happy. Setting the rear sway full soft and reducing rear tire pressures will lessen the oversteer. A 22mm front sway will also reduce oversteer by shifting weight to the rear, though with a 21mm bar in now it won't be a big effect. You can also swap out the front spring pads for 10mm thick pads to lift the front and shift weight to the rear. If noise isn't a concern, remove the rear spring pads for the same reason. After that, the options left are to add some weight to the rear or take some off the front. Deleting the PS pump and AC makes a noticeable difference, but that might not be an option on a street car.
                  The car makes it possible, but the driver makes it happen.

                    So to adjust the bar I move the end links all the way to the end of the bar, is that right.

                      yes moving the links further to the end will result in more leverage on the bar making it less effective or (softer).
