Installation Guides Spring Rate Tech Circle Track FAQs Below are some frequently asked questions. Rear Geometry These methods, good or bad, can be confusing at times. If the front geometry is not designed correctly, then as the car dives and rolls, the RF camber relative to the racing surface will change and the tire will lose grip. Not having true continuity between spring and jack plate is an undesirable trait. To fix this, reduce the rebound rate in the LR shock and/or stiffen the compression rate on the right-front shock. The amount of difference you need is directly influenced by the installed motion ratio of the spring and the spring rate. Once you have evaluated all of the above and feel fairly confident that the car is set up correctly, you should then work to tune the transitions into and off of the corners with the shocks. The following information and diagram may be beneficial for installing and checking mounting points. asphalt metric street stock setup Some manufactures even feel and state that racers should monitor a springs free height instead of its rate. (2.) Suspension | Apex Customs This applies equally to the shackle and slider ends. This condition is very hard to detect from a driver's perspective. 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. We have continually pressed these issues because of the extreme importance they have. Designing a spring also requires considering the wire size, O.D., I.D., free height, compressed height and static loads that are to be expected on each spring. But the most useful rear steer will only occur on acceleration and not at mid-turn. Generally the spring rate will increase when the following is done or decrease on the opposite. This induces rear steer when the car squats on exit. The RF and LF wheels will always experience changes in camber as the car enters and rolls into the turns. Decrease the Pre-Load on the Front Stabilizer Bar.

This can make the car very loose and we need to adjust the suspension components so that it will not steer in this manner. The entry and exit to and from the middle are affected by transitional components in the car. A particular car at each racetrack will require a certain amount of rear stagger. The more third link angle you have, the more antisquat there is. However, tie down shocks are becoming less and less desirable. However, the cost is three times greater. Use a Smaller Front Stabilizer Bar. Spring rates range from 200-pounds to 225 pounds, plus you can specify three ride heights. How much does each spring compress? I have always believed in priorities because you can make gains faster when you solve the high priorities problems first. The springs are tall and constructed from small-diameter, high-tensile chrome silicon wire, providing the correct rate for the listed application. Negative aspects might include excessive bumpsteer (more than 0.030 bump in or out in for each inch of travel is considered negative by most designers), excessive Ackermann (more than a 1/4 degree added steer in either front wheel in 10 degrees of steering input is considered excessive), and incorrect steering quickness. Although they are the oldest, they seem to be the least understood. The setup is balanced when the LF and LR tire temps are similar. Are their hidden cost in the spring purchased? Rear Steer Design - Chassis Setup For Improved Cornering - Circle Track Shocks affect the motion of the corners of the car and therefore the placement of loads during transitional periods. SERIAL NUMBER:Having a spring that has its own serial number is important. SHADOW RACING PRODUCTS973.684.7270www.shadowracing.com. 2. Remember that drag is an important aspect of aero design. When the car is not balanced, the neutral handling does not stay with the car for very long. Tire temperatures can tell a lot about the setup and where we need to look to fix the setup balance problem.

Designed for drag racing where maximum weight transfer is needed. Search by Part Number or Category Apparel Bump Stop Springs Coil Over Springs Conventional Coil Springs Leaf Springs Due to the fact of the popularity of the leaf spring system, we felt racers may want to understand more about how the suspension actually works.
