Detroit Speeds Test Mule 1.C3 Corvette is All That.Sometimes the things that dont stand out are far more revealing than the things that do.You might think that the 5.LS3, epic 3. 35mm wide rear meats and deliciously retro livery on Kyle Tuckers 1.AcuRite has been threatening the release of this product for well over a year, and its finally out.Being a bit obsessive about data in and around my home, check.Corvette tell plenty about the cars go fast intentions, but they dont.Any poser can copy and follow this exact same formula and pretend like theyre the real deal.If you really want to know what this cars all about, check out those AN fittings.As ridiculous as that sounds, the logic behind it is so backward that it might actually make sense.Monkeying around with worm clamps, NPT fittings, and thread sealant simply isnt an option during the heat of battle, so everything from the fuel rails and the radiator hoses to the coolant overflow tank and the brake and oil lines on this C3 prioritize easy serviceability and leak free seals.Whats even more revealing than the fittings themselves are the components theyre connected to, like the dry sump oil system and tandem master cylinders.C3 Setup C3 Set Up Email' title='C3 Setup C3 Set Up Email' />Welcome to C3.Chlorine Chemistry Council.This site is currently undergoing a major redevelopment, please check back after October 30th to see.It takes a real racer to know that many a wet sump engine has puked oil out the breathers on the autocross, and a quaint proportioning valve doesnt always offer the flexibility in front to rear bias that late braking maneuvers demand.Granted that the AN fittings themselves dont define Kyles Corvette, they represent a full bevy of hardware lurking just beneath the surface that broadcast this cars true objective of kicking some serious heinie on the autocross.As the owner of one of the top suspension manufacturers in the businessDetroit Speed Inc.C3 to the entire C3 platform at large.To catapult the redheaded stepchild of the Corvette lineage i.C3 into the upper echelon of Pro Touring performance, Kyle Tucker and the DSE crew invested countless hours developing an all new line of suspension components on its in house test mule.It just happens to be Kyles personal car.Nevertheless, personal car or not, it doesnt change the fact that it offered Kyle a great excuse to build a car hes always wanted anyway.While midyear elitists love taking cheap shots at the Corvette generation that endured the brunt of the 7.C3 Corvettes prolific road racing achievements made quite an impression on the youth of the era.As such, when planning out the build, Kyle wanted to pay tribute to the wildly successful C3 endurance racers that routinely showed up the Europeans on the worlds largest stage.My favorite C3 road race Corvette was the John Greenwood big block powered car that competed at Le Mans on BFGoodrich street tires.

I also love the Greenwood design livery, says Kyle.Although the DSE C3 may bear a passing resemblance to the fabled Greenwood machine, thats where the similarities end.Beneath the reworked fiberglass, the DSE machine is an entirely different animal.We purchased and built this car as a development vehicle for our new C2 and C3 suspension products.Every new product line we introduce is first installed on one of our own cars, Kyle explains.With plans to run super sticky and super fat 3.BFGoodrich Rival S tires, DSE had to seriously beef up the Vettes chassis and suspension to endure prodigious cornering loads.Consequently, DSE designed beefier control arms up front and replaced the factory leaf springs with coilovers at each corner.DSE drop spindles at the front and back enhance the stance while also optimizing suspension geometry.The real magic, however, happens in the back where DSE utilized its engineering acumen to completely redesign the primitive factory independent rear suspension setup.While the stock C3 IRS was plenty capable for its day, modern levels of grip can make it go kaput in a hurry.The problem stems from its fundamentally archaic layout where the halfshafts also serve as the upper control arms.In order to replace the failure prone universal joints with more flexible CV joints, DSE added links to support the top of the spindles, thus eliminating lateral load from the drive axles.Adding some links here and there isnt exactly a bolt in affair, and required completely revamping the entire IRS assembly.I think the rear suspension is the most unique part of this car.Our new Corvette product line features a rear cradle system made from cast aluminum sections, and DSEs own forged aluminum rear uprights.This converts the rear suspension to a multilink system that uses CV joints instead of the prone to break U joints, Kyle Tucker explains.The all new front and rear suspension geometry is very adjustable and works very well with the stock frame.We also designed and developed our own unique front power rack and pinion steering system to complement the suspension upgrades.Of course, handling alone doesnt win races, so DSE contacted Mast Motorsports and ordered up one of their proven LS3 small block combinations.Stroked to 4. 16 cubic inches, the combo puts out a respectable 5.NASCAR inspired Hightower four speed manual trans.Brembo six piston clamps are tasked with bringing the fiberglass missile to a halt.Speaking of fiberglass, packaging such massive rollers beneath the Vettes skin required a fair amount of cosmetic surgery.It seems like no two Corvette fender flares are the same from car to car.Once we installed our suspension and Forgeline wheels, we began crafting a new set of custom flares, Kyle recounts.Michael Neighbors in our body shop started with a set of L8.In an effort to keep weight to a minimum we also installed fiberglass front and rear bumpers.We finished everything off with an LT 1 hood.As youd expect from a purpose built competition machine, the DSE Vette performed quite well in its autocross debut.After finishing the car just hours before its first run through the autocross, it won its class at the 2.Raleigh, North Carolina, Goodguys event, Kyle recalls.Despite that initial success, the DSE team isnt sitting back and gloating over its achievements.We learn every weekend the car goes out and competes, and we try to keep it going every week so we can log more time on the parts and gather all the information we can.The car has undergone several continuous improvements as we get closer to officially launching our Corvette production parts.Sounds pretty hard core, but what else would you expect from a crew that cant be bothered with worm clamps, NPT fittings, and thread sealant.Tech Check Owner Kyle Tucker, Mooresville, North Carolina Vehicle 1.Corvette Engine Type GM LS3 Displacement 4.Compression Ratio 1.Bore 4. 0. 70 inches Stroke 4.Cylinder Heads Mast Black Label aluminum LS3 castings, 2.Rotating Assembly CalliesCompstar forged 4.Mahle pistons Valvetrain GM lifters and rocker arms Camshaft Custom Mast hydraulic roller specs classified Induction Stock LS3 intake manifold Holley throttle body, Dominator EFI standalone ECU and wiring harness custom DSE air cleaner housing Ignition Stock Exhaust Hooker Blackheart long tube headers and 4 inch muffler custom DSE X pipe Cooling Stock water pump, C R Racing radiator Output 5.Drivetrain Transmission Hightower four speed manual, American Powertrain bellhousing, Centerforce clutch, Dynotech driveshaft Rear Axle Stock housing, Driveshaft Shop halfshafts, 4.Chassis Steering DSE power rack and pinion Front Suspension DSE control arms, drop spindles, and sway bars DSEJRi double adjustable coilovers Rear Suspension DSE aluminum cradle, control links, drop spindles, and sway bar DSEJRi coilovers Brakes Brembo 1.Brembo 1. 3 inch rotors and four piston calipers, rear Wheels Tires Wheels Forgeline GA3.R 1. 8x. 11. 5 front, 1.Tires BFGoodrich Rival S 3.
