![]() ![]() That is determined solely by the acceleration and the location of the CG. Whether a car squats or rises has absolutely nothing to do with the weight transfer. That is, a point above the line will cause the car to squat and vice versa. When the IC is behind the rear axle, the effects are reversed. Normally, I would, at this point, simply say that, if the IC is above the no squat/no rise line, the rear end of the car will rise on launch if below, squat, but TBucket's geometry probably places the IC behind the rear axle so I have to add a few more words. The no squat/ no rise line passes through the rear tire patch (actually, about an inch below) and through the intersection of two other lines, one a horizontal line through the center of gravity and the other a vertical line through the front tire patch. The instant center location is the point where lines through the upper and lower links intersect, as viewed from the side. To expand on Triaged's comments, you can determine whether a car is going to squat or rise by the position of the "instant center" relative to the no squat/no rise line. sorry for the quality, i dont have a scanner, just a webcam Theres realy no way to set up a car right in the garage, its just a case of getting it close and taking the car to the track to try it out, this is why a REAL bar setup from jegs or such has such a rance of attachment points on the frame and differential The so if you take the car to the track and the tires just spin on launch, add some more antisquat by repositioning the formard ends of the bars More then 100% and the rear end of the car pushes up Less then 100% antisquat and the bac end drops during a launchÄ®xactly 100% and the back end stays level on launch as if both bars are infinatly long and this imaginary point should be someplace in the middle of the carÄrawing a line from where the rear tire meets the ground, thru where the bars "meet" and to dirrectly above the front tires gives you a visual idea of the amount of antisquat the rear suspension has Link bars ahve to "meet" someplace in space. ![]()
