    stick the RR better

    what r some of the things I can do to stick the RR better . need to be able to drive a little harder through the corners. need a little more side bite. car handles good right now. just looking for a small general change to make. I know I can add angle to J-bar but what is a small change to make that would not compromise handling much.

      im needing some help my self, my car is very good in and to the center, but i can feel like the rr like its skipping coming off the corner on the throttle. i dont want to make it any tighter getting in or in the center just need to plant the rr. im int the 2nd hole up on the lrt rod and 3rd hole from the bottom on the lrb rod, about 70 lbs wedge, and the 4 links are at std lengths??? thought maybe about shorting the right side but not sure if that will help. thanks Dave

        rt rear

        My thought would be is add some wedge what you feel is over steer in the rear because its steering like a fork truck. I would try like a 120 to 140 LT rear and go to a 200 or 175 in the left rear will give the left rear more traction. U might try a 375 in fiftharm out around 34 to 35 inches out from center of housing . Just some thoughts

            what would be better to stick the rr and get hooked up coming off the corner on the throttle???

            1) shorten right side wheel base 1/4- 1/2 inch ??
            2) add wedge??
            3) drop bottom lr bar down down a hole??? also dont the bottom lr rod by dropping it take some rear steer out?? thanks for any help possible.. dave

              bite

              Well I would try dropping the bottom bar first and yes it does take a little steer out but indexing the birdgage in to the spring will add traction will also free it up a little On entry depending on how you controlled the throttle. And you drive the car straighter if its better and want a little more then try the wedge . Try not to change the bar lengths running different lenths only fixs a issue your having some where else.
              1 bar down this also will gain a couple of degrees of upper bar angle along adding into the spring.
              2 need a little more and your close add a little wedge.
              3 consider running a stacked spring set on right front with the lock out. This lets you pin the right front but still give you a stiff spring to give the left bars to push off of to add traction in the left rear. RE SUSPENSION. IN MOORESVILLE NC can help you out 704-664-2277

                All of these make the car "tighter" on exit. I wouldn't call that "sticking the rr". If your rr is working harder on exit, you would be looser. 2 and 3 will do nothing for you if you lack sidebite. 1 may help if you think you lack sidebite, but are really chasing the rear of the car up the track because it is steering so much.

                If you are just a bit loose on exit, then 3 is your best bet.

                  when evaluating handling to make changes, look at all 5 points of the corner.

                  1) Entry on throttle
                  2) Entry off throttle
                  3) Middle off throttle
                  4) Middle on throttle
                  5) Exit on throttle

                  Identify what the car is doing in all 5 areas, and from there you can decide what change is best, since changes tend to affect multiple areas, as Mastersbuilt pointed out. Simply saying "i need more side bite" isn't a good way to determine what change you really need.

                    if my RR lower is already level. If I drop another hole at frame ( making it a downward angle - from back to front view ) will this be OK or is that to far to lower the RR lower rod ?.

                      try taking some rebound out of rr . it will drive off rr more. but may be a little loose but will have more rr drive from center off.

                        Define "skipping"...
                        Skipping as in "bouncing" or skipping as in "sliding"?
                        If its "bouncing", you may be too soft on compression in your RR shock.
                        Stiffening the RR shock would help control the bouncing/hopping and free you up
                        some on entry and center.

                        My apologies for Hijacking, I just saw an opportunity to help somebody.

                          That will be ok and should give you more traction at the rr, and less rear steer.
                          Looks like your post got hijacked!

                            well we ran agin this weekend, ran a little better but where still not there yet. where killing them getting in and to the center, but i have to wait longer then every one else to pick up the throttle. im keeping to car straight not throwing it in, but it wants to spin the tires alot from center off on the throttle. we had the 4 links just about the same as last week lrt 2nd hole up- lrb 3rd hole up- rrt 2nd hole from bottom- rrb 3 hole from bottom. with the excepting of the lrb rod done in the 2nd hole after the races. it still seems to me like the car wants to rotate do much on the throttle, i had to rrt rod 2nd hole from bottom, then went back out with it in the bottom hole and agin i could really run it in but had to wait along time to pick the gas back up, i was wondering if changing from a 225 to a 200 rr spring might help??? of even clamping the dummy shock?? i heard it might be better then running the normal clamp lr.

                              Add 50# of lr and move the rr bottom bar down a hole.
