Usually, improved mid-turn handling offers the most gain in overall performance, and that is why we start there. Antidive and antisquat are mechanical influences that can help our transitional phases of entry and exit. Disc brake spacers will further impact the height. Using antidive on the RF and prodive on the LF helps square the front end to the racetrack and, along with a softer spring setup, provides an enhanced aero effect. No more than 10-15 pound difference, excess split makes car tight. Tapered leaves have inconsistent run out, thus inconsistent spring rates. Other helpful hints are available from our technical experts. The following is a list of things that can make the car not want to turn or make the car loose. Decrease LR Shock rebound and/or increase RF Shock compresion. With excess Ackermann designed into our cars, on purpose or not, we can gain a lot of toe-out, which causes our front tires to work against each other. Furthermore, if in the event that there is a spring failure, we can trace the springs history and make up all the way back to the wire source. By purchasing springs that are already accurately rated, you will not have to pay your engineer ($$), team manager ($$), or crew chief ($$) to rate springs that you have purchased. The longer lever arm created by the adjustment scenario in the prior paragraph compresses the RF spring more than it would have in our baseline set up. A slight amount of rear steer to the left has been shown to help provide more traction at the rear and bite off the corners where it is needed. Installing the leaf spring directly to a fixed axle seat (no upper or lower rubber mounted pads which are common on GMs) will increase the overall spring rate, wrap-up rate and lateral rate, as well as the braking rate. This applies equally to the shackle and slider ends. However, it does affect the installed rate. Stock cars using the metric-style four-link rear suspension usually need to do this just to achieve a balanced setup with the high rear moment centers in those cars. If you could slide the MC to the right, or outside of the turn for you road racers, the front end will get stiffer. WAYS TO ENHANCE PERFORMANCE AND LONGEVITY OF LEAF SPRINGS. Through our research, diamond trimmed leaves produce the most consistent spring rate. 269-463-8000; Sign in or Register; Compare ; Cart. Higher arch springs tend to work better on the dirt tracks whereas the lower arch springs perform better on the asphalt tracks. LIT-718 80291 1997 - 2004 Mustang Radiator. Frost Racing - Setup Tips Balance the Front and Rear stiffness. When the front bushing is allowing the front leaf spring to pivot, it transfers all the side loads and lateral forces to rear portion of the leaf spring and shackles or sliders, which were not designed to handle the additional stress. The settings, including the moment center location, really do dictate how all of the other parts and pieces of setup will work. Although the camber change is quick and the wheel returns to normal camber settings a short time later, once the push starts, it is hard to stop it without slowing down. 4-Link The track radius used to determine stagger matters the most where the car will be accelerating. by 72firechicken Tue Jun 21, 2011 1:34 pm, Post The stiff LF spring setup does not work well on tracks banked over 10 degrees. And, it must be economically applied.
