Ok were running a three link setup using a quickcar pullbar on top with both shocks infront of the axle,the shocks are 4 inch infront of centre line,were wondering what effect moving closer or further from the axle would have,were looking for an ultimate grip level for the straights. would we get more forward bite with shocks infront on top or behind?? Also in a perfect world what pull bar angle and position would you guys run,were nine inches above centre of axle 5 inches behind,36 inch long and 15 degree down,would dropping the whole bar help bite or make it worse?? any input or views are much appreciated thanx

where are the springs located??? On a 3-link you want to put the LR in front of the housing and the RR behind. Moving the pullbar down in front (adding more angle) will increase the "instant bite" but the car will lose the bite quicker down the straights.

both springs are on shocks infront of the axle,this is working nicely but im questioning which placement would generate more grip from an acceleration point of view,say having to lift off the gas then back on it on the straights,not taking into account the cornering effect. also i understand the pull bar angle having an effect but have confused myself as to the effect of lowering the whole bar,to my way of thinking if i lower it the leverage becomes greater therefore having to stiffen its rate but as a positive i could get more anti squat for less angle which inturn could reduce wheel chatter and help the loose condition on entry.... has anybody ever tried bringing the whole bar right down almost to the casing and running say 10 degree ??

I haven't tried that, no. But with the spring placements, with both springs in front you are indexing towards both springs under accel, which should increase traction. Of course I could see how corner entry would suffer, but if your not worried about that....... I suppose both up front would be the way to go. Like I said I haven't tried or experimented with the pullbar height, but also remember when you move it closer to the differential, be sure to make for sure that the bar isn't contacting the housing under accel/indexing.

ok thanks for the advice,i guess i will have to try it and see,im also going to try moving the shocks further away from the casing and see just how far we can go,then maybe offset one more than the other but both still infront,seems like it could work well....maybe lol!
