Lower the front LR trailing arm mount. In situations where the exit portion of the track provides less traction and/or the corner is more flat, we might need to develop more rear traction upon acceleration. The farther to the right of the centerline, the less the front end will want to roll. It's been three years since we discussed the subject of handling fixes. Let's go through each item and explain how they can affect our turn entry and exit performance. Leaves that are tapered on the ends are generally used for mass production applications which do not require the close tolerances and consistency in the spring rate that racers demand. Plan out changes that could help improve performance or durability. The components that locate the rear end must be evaluated and set correctly. Whenever a manufacture sets up to run several hundred springs of one particular rate, the end result is less than perfect. The advantage of this style is that the spring is lighter than the multi-leaf. Pivot bushings are bushings that were designed to remove the bind between the chassis and the spring. Bushing choice will also affect spring life, and more importantly, spring performance. In addition, the leaf spring suspension is more forgiving on chassis set-up errors. With the advent of the BBSS setups, both front wheels experience a great deal of camber change as the chassis dives 3 inches or more in the turns with an accompanying reduction in chassis roll. If a user was to lose their sheets then we should be able to pull the data up at a later date. Be careful not to overdue that. Leaf Spring Technical Information. Toggle menu. Clipshave a profound effect on spring rates. 3. Speed up and do a few hot laps, and again note the position of the steering wheel. There are two different way to run stacked springs. By far the most common handling malady historically is inability to turn. The following diagram illustrates a top view of the rear leaf springs which may be useful in determining a splayed or toed in pattern of the oval track Chrysler set up. That is the best description of the result of the dynamic force that influences each system. We do not want to try to solve turn entry problems with the brake bias, we only need to make sure the car stays neutral in handling when the brakes are applied. So, here is, in order of logic and importance, a list of setup parameters we need to address to make our cars fast and consistent. Shackle rigidity and length play a role in the installed rate as well. 10. An inconsistent clip, such as the Kwick Clip or Banding Clips with rubber insulation, will transfer into an inconsistent side bite. The springs are tall and constructed from small-diameter, high-tensile chrome silicon wire, providing the correct rate for the listed application. Address: 304 5th Creek Road, Statesville, NC, US, 28625; Smaller gains can come later on after the more important aspects of setup are resolved. Installing a torque device combined with these types of suspensions will cause the wrap-up rate to be excessive. Increase the Rear Tire Stagger. If one corner of the car is shocked stiff, then as that corner desires to move in compression, more load will be retained by that corner as well as the opposite diagonal corner of the car during the compression cycle only. Increase the Caster. Circle Track - Asphalt; Circle Track - Dirt; Open Wheel - Sprint Car; Off-Road & Tractor Pulling; All Categories ; Shop By Price $0.00 - $98.00 . Place the straight edge on the spring so that it intersects the front and rear bushing. I can't tell you how many times I have refined the MC location in a car and had it totally change the way the car turned, for the better. Here is an explanation of balance related to the dynamics of the race car. The setup we choose needs to be arranged so that the dynamics are balanced between the front and the rear suspensions. On some tracks, with cars using Detroit Locker rear differentials, the accelerating portion radius will be larger than the mid-turn radius.
