    left front spring question

    Ive been talking to some people and there running 350 or 375 front right spring. Right now i have a 400 on the right front and am having a problem with the car not wanting to rotate on entry, Basically i have to pitch it and get the ass end broke free using the gas pedal.

    Lower the left front spring will do what?

    when you say the car will not rotate on entry is that on the gas or off the gas? on the brake or off the brake? Where are your 4 bars at? what size track? what spring do you have on the right front?

      never heard of anything even close to that soft around here. we run a 500 and sometimes we will go up to a 550 if it feels a little to loose on entry. i would think that by going to that soft of a spring on the RF you are probably using it as a crutch for something else that is giving you fits. what does the rest of your setup look like?

        meant right front

        I meant to say right front. 3/8 mile car. Car won't rotate off the gas but i have to jump back on gas to get the ass end to come around. Or if im off the gas and a jab the brake it will come around that way on the brake but not off.

        top bar top hole on left, on right top hole second hole from top, both bottom bars slight angle up

          rf

          If you off the gas you need to stiffen to loosen running softer rf off gas will tighten.

                i have a 225 on left rear and a 200 on rr. Right lower bar all the up was far is it can.

                So i should raise the jbar and maybe put a heavier spring on the right front

                  Stiffer LF will pull the front of the car into the turn when off of the gas OR on the brake as it will catch more weight and cause more drag.

                    If your brake bias is more towards the front.

                      What LF spring are you running now?
                      Softer LF should loosen entry as it will take weight off of RR.

                        RF 350 Lf 500 on RR 225 and RL 200. and put the J bar in the second hole from the bottom of the bracket. Raising the j bar will loose the car up and lowering it will tighten the car. I never run j bar in the last hole except when the track gets really bad dry slick. And also when the track gets dry slick with these kind of settings. Rock the car over by put 6 or 8 turns in RF and 6 or 8 turns LR but, keep same number amount of turns in. This make the car stick better in turns and help you come off better. The 350 on RF should make car enter the corner easy. If its to much roll over the RF go up on air pressure like 11 ibs. or change the spring to a 375 but, only go 25ibs a time. Hopefully this help you and confuse you. All i said has help me alot and other drivers i have raced with. I would keep my bars on TLB top hole, BLB middle hole or top. TRB second hole from top. BRB bottom hole.

                          That is true! I would LOVE to have $10 for each of the the bias adjusters I have found set up wrong thru the years. We had one that all to the front you could grab the front tires and turn them with your hands and the rear were still locked up.
