High Travel ConventionalFront Coil SpringsTECH-TIPSWhen rate testingconventional frontsprings it is importantto ensure the helix(rise) in the ratetester is the sameas the helix in thelower control armof the race car.For a complete listing ofhyperco tech-tips visit ourwebsite at:www.hypercoils.comTECHNICAL ASSISTANCEThe Closed End Advantage.Racers continue to chase the configuration and springrate of conventional front springs in order to get moresuspension travel on the race track. With Hyperco’sHigh-Travel Conventional Front Springs, we’re bringingour closed-end NASCAR style front spring technologyto the overall Hyperco Conventional front spring line.With traditionally designed, open-on-pitch frontsuspension coils, very little contact is made withthe riser. This means very little of the end coil ofthe spring will deaden out during the early portionof spring deflection. This creates a very progressivespring rate through the initial stages of deflection.The closed-end design of Hyperco’s High-TravelConventional Front Springs directly impacts thenumber of active coils that deflect during springcompression.The advantage? With our springs, it takes verylittle deflection for the coil to make full contactwith the riser, thus the spring reaches its stabilizedrate much sooner in the deflection. Static load isreached with less spring deflection, leaving moreon-track dynamic travel. And more travel on theracetrack enables more aggressive and fasterset-ups.(a) TheirsOur Stacked Dual Rate Spring System PackageThe Hyperco Difference? It’s Tunable!(b) HYPERCO(a) Their spring with open endinteracting with riser(b) HYPERCO Spring with nearlyclosed end interactingwith riser.The Hyperco (stacked) dual rate spring system has a difference… it’s tunable! A widevariety of racing categories have realized the winning advantage of Hyperco’s adjustabledual rate spring system. The Hyperco stacked spring hardware (Floater/Spring Divider inconjunction with a ring on the shock body) manages deflection/rate. It lets you controlthe transition from a relatively soft combined/dual spring rate for optimum weighttransfer and wheel movement, while also enabling you to tune the suspension at ahigher secondary rate that provides for maximum compliance and wheel/tire loading.Variable(Dual Rate)Technology6

CompositeLeaf SpringsLighter. Stronger. Faster.Hyperco Composite Leaf Springs are precisionmanufactured with an epoxy matrix compositematerial. Adapted from the aerospace industry,this material provides extraordinary strengththat is 70% lighter than steel.Molded to an exact true arch, the Hyperco CLSretains its shape for life. No need to put a caron jack stands ever again!On the track, the CLS provides more side bite offthe corners. It allows teams running leaf springsto be consistent race after race without having toconstantly measure, monitor and change theirsprings for loss of arch/sagging.Less weight and retention of the design archcombine to make the CLS a high performance/costeffectivealternative to steel leaf springs. The initialcost is a value based on the incredible service life.Leave the steel on the streets – hook-up withthe Hyperco CLS performance advantage.Performance-TunedCorvette C3, C4, C5 & C6Composite Leaf SpringsHyperco performance-tuned CorvetteComposite Leaf Springs enable the serious Corvette ownerto enhance the suspension performance of their car.C5 Series Available for both street and track –NEWThe High Performance Street Series (HPS)provides improved cornering ability, road feel and initialresponse while maintaining a quiet and comfortable ride. Rideheight adjusters, equipped with Delron pads, offer a wide rangeof tuning options. This enables the C5 owner to set the look andhandling of the car to their preference… mild to aggressive.The High Performance Track Series (HPT)offers the C5 owner a “race-ready” spring rate option for autocrossing, track days and competitive racing. The Delron padequippedheight adjusters support a wide range of set up choices,enabling the car to be tuned for all out performance.TECHNICAL ASSISTANCE WITH HYPERCO PRODUCTSTECH-TIPSMEASURING LEAF SPRINGS. To measure the arch, place the springon a flat surface with the arch up. Measure from the floor tothe bottom of the spring (“H” in the diagram), and then subtract3/4” from the total length.For Chrysler the overall length (eye to eye) is 53 7/8” and thepin to eye length is 20 1/2” (“L” in diagram). For Chevrolet, theoverall length (eye to eye) is 54” and the pin to eye length is 25” (“L” in diagram).For a complete listing of hyperco tech-tips visit our website at: www.hypercoils.com7

Q. Is it normal for all springs to bowunder load?A. Some brands of springs “bow” excessively under load causingthem to make contact with the shock body. This contact notonly affects the car’s corner weights but also puts additional heatinto the shock through friction between the shock body and thecoil. Some manufacturers have tried to put a band-aid on thisproblem by using a plastic sleeve to stop the bowing from wearingthe shock body. This may stop the shock body from wearing,but anytime one of the coils rub the shock body/plastic sleeve,the effective spring rate goes up considerably, and the car’s handlingchanges. Another compromise “fix” some brands haveresorted to is a barrel-type spring. While this design providesmore clearance between shock and spring I.D., it often causesexternal clearance problems requiring changes to the chassisand will not deflect with a constant “linear” rate, adding anothervariable to your chassis set-up. It has also been declared illegal bysome sanctioning bodies. Hypercoils are designed and manufacturedto resist bowing under load.Q. My budget springs will lose free length fora while, then they seem to stabilize.A. Are you sure they have stabilized? When do you know theyhave stabilized? With the competition in every category oftoday’s racing, you cannot afford to waste time guessing whatinferior springs are going to do. Unstable free lengths/installedheights will keep you from developing a consistent chassis setupand will put your team at risk for disqualification at ride heightinspection. Hypercoils will not lose free length/installed height.Q. What is the proper method for checking ratewith my portable checker?A. Unfortunately, we know of no portable checkers that willaccurately measure rate with repeatability. The scales we use totest and calibrate springs weigh over 4000 lbs. This mass isrequired to ensure the spring is deflected with both ends remainingsquare and parallel through the entire travel. Measuringdeflection accurately is another difficulty with portable checkers.The Hyperco scale will measure accurately to one thousandth ofan inch. We have our own calibration weights which are certifiedby the National Bureau of Standards to be accurate to .001 percent.Measure Your Springs Frequently!You’ll discover why teamsare switching toHYPERCOILSlength and is not being slammed/hammered coil-bound,as might happen if the car gets airborne and bounces on onecorner,hitting curbs,etc.,our coils will not take a set. We still oftensee racers who unload their coils while sitting in the pits or at theshop. If a spring takes a set while sitting in the pits or at your shopor in transport… it is not suitable for racing.Q. What is rate overlap?A. Rate overlap can occur when the manufacturing tolerance isover one half of the rate change. For example, say you desire arate change from 475# to 500#. If the manufacturing tolerance isplus or minus three percent (as some manufacturer’s coil-oversare), there is a very real possibility that you will not be making thechange you desired. You could be taking out a 489# rate andinstalling a 485# rate! Why? Because 475# x 103% = 489# and500# x 97% = 485#. Worse yet, you could be taking out a 461#and replacing it with a 515#. When a car’s handling did notimprove or maybe even got worse, what would be the next step?This is an even bigger problem with Conventional type springs.At Hyperco we invest a considerable amount of time and moneyensuring that the spring rates we offer are accurate and consistent.Even though our guaranteed tolerance is plus or minus twopercent, Hypercoils are generally well within one percent, and wedo not offer rates that could overlap. Hypercoils are purchasedand relied upon by the top teams in all forms of motor racing…even though many of them could have other brands supplied tothem free of charge!Q. Is it necessary to unload Hypercoils whilethe car is sitting in the pits or when travelingto and from the track in our transporter?A. No it is not necessary to jack the car up while in the pits, noris it necessary to block the car up while it is being transported!Hypercoils are designed and manufactured from ultra high qualitymaterials to withstand the rigors of motor racing conditions. Itdoesn’t matter if one coil is holding the entire car up in the pits.All our coils are designed to be able to be taken to solid withoutcausing any damage. As long as the coil fitted is the correct9

Hydraulic Load-CenteringSpring Perch HardwareHyperco…Engineering that’sSecond to None.Optimum race car suspension components mustbe designed for consistent performance, an infinitefatigue life and absolute minimum weight.At Hyperco, we look at every aspect of design.– Is it as light as possible?– Is it the optimal design that can be produced?As we search for the answers to these questions,we continuously research and develop materialsand techniques to further our product line.Through our research and development efforts,we’ve designed a collection of new and innovativecomponents. They are designed, tested andmanufactured with the same attention to detailthat has made our other products winners on theracetrack—ensuring that these components alsoprovide a Performance Advantage.Off-Track InnovationEquals On-Track Breakthroughs.In racing, tire grip and low wear rate, are critical for maximumperformance. Unfortunately, one of the common characteristicsof coil springs is that they do not naturally distribute their loadevenly around the face of their end coils thus generating a lateralload. The lateral force creates a bending load in the shock absorber,significantly increasing its friction; the result is lower tire grip andincreased wear.The Hyperco/ICP Hydraulic Load Centering Spring Perches substantiallyimprove performance by allowing the spring forces to remaincentered on the damper. By precise shaping of the sealing wall ofboth the perch and cylinder body, the perch can freely tilt as neededto evenly distribute the load over the face of the perch. The result,a reduction of bending load on the shock absorber of up to 96%along with an enhancement in mechanical grip at the tire.Racing teams in Formula One, Champ Car, Indy Car, and Trans Am,along with Formula Atlantic, Midgets, Dirt & Pavement Late Models,Motorcycles… etc., benefit from the winning performance of theHyperco/ICP Hydraulic Load-Centering Spring Perch components.Available for all popular shock absorber brands/applications.ECHNICAL ASSISTANCE WITH HYPERCO PRODUCTSTECH-TIPSHyperco/ICP Hydraulic (load centering) Spring Perches should be installedat both ends of the spring when running free lengths of 10” or less. Forfree lengths above 10” it is advisable to run them on only one end.10For a complete listing of hyperco tech-tips visit our website at: www.hypercoils.com
