WHAT SEPARATES THE HYPER RACING X11/X7 CHASSIS FROM THE REST OF THE PACK?

Design: Our Mechanical Design Engineering Team utilizes the principles of vehicle dynamics and applies those proven concepts to the chassis design and the chassis setup.  

Build: Every single build is unique. This is not a cookie cutter car. The Hyper Chassis can be configured for winged or wingless, for any size track, and to fit any size or weight driver. You’ll notice when you visit the chassis order page or call to order that we literally custom build the chassis to the individual. Once you have your perfect chassis, you can configure it even more and fine tune to your needs and preferences. Or just leave it alone. Our standard, proven setups work great!  

Support: We take it one step further and share this bank of knowledge through our robust customer support structure which includes live support, tech articles, videos, and seminars. We’ve been doing this since 1994. New to Hyper Racing or to the sport of micro sprint/mini sprints? Be sure to read the Hyper Racing Story.  
 

X11/X7 CHASSIS HANDLING ADVANTAGES

It's not good enough to say our cars handle exceptionally well and give you an advantage. Here’s why.

• Wishbone rear suspension instead of a z-link rear. 600cc Sprints have a really low center of gravity height (CGH). CGH has a huge effect on chassis handling. A low CGH kills forward drive, because it reduces the amount of weight that transfers from the front to the back under acceleration. A z-link rear has negative anti-squat meaning it lowers the CGH excessively under acceleration killing drive. The wishbone has a very large anti-squat which holds the car's CGH up under acceleration creating a lot of weight transfer to the rear and enabling maximum forward drive.
• Longer wheelbase that provides a 4% increase in rear weight bias over the competition. This improves forward drive and helps the car in rough track conditions.
• 7” rear shocks to prevent bottoming and topping out. Whenever a shock tops or bottoms out, the result is a very inconsistent handling chassis.
• Front shock sliders. Due to the diversity of shock manufactures and the lack of standardization on the overall length of shocks, as well as changing from winged to wingless racing, it is necessary to have an adjustable shock height system on the front of the chassis. The design of our new shock slider (38-901) allows for quick shock changes without the clamp moving on the tower. Also provides the tunability of when the shock tops out and bottoms out. Shocks that top or bottom out when not desired will cause an ill-handling chassis.
• Configurability in so many ways! The X11/X7 is very configurable to adapt to drastically different track surfaces and types of racing, driver styles, and driver height & weight. These all play a huge role in chassis handling.
  • Choose the long or short wheelbase. Our longer wheelbase is standard and recommended for almost all situations except when a very lightweight driver is behind the wheel. These drivers suffer from not having enough rear weight bias. The short wheelbase option gives that back to them.
  • Choose coil over or torsion front suspension. Both work great, but some driving styles prefer one over the other. Coil front is our standard and tends to work better on a slick track.
  • Choose Jacob’s ladder or panhard bar rear lateral linkage. The Jacob’s ladder is now the choice of 98% of our chassis builds. But some drivers prefer the tighter feel of the panhard bar.
  • Choose between 40.5” and 42” long front axles. Typically, racers will use the 42” for wingless and 40.5” for winged racing, but drivers sometimes always like the feel of one over the other.
  • Right side wishbone has a second mounting point. Allows more rear steer and anti-squat.
  • Driver size and weight accommodations. When running the axle forward or if you want to move the seat to the very back for very large drivers, it may be necessary to remove the brake floater and put the brake on the right side bearing carrier. We offer configurations to do both.

WHAT IS THE X-FACTOR?

The X11/X7 adjusts to fit any size driver. It’s the X-Factor!

• Adjustable Pedals: fits any height driver, changes in minutes. The industry has seen nothing like this, in any class of racing. Hyper Racing was the first to put adjustable pedals in 600cc Sprints.
• Adjustable Steering: Tilts up and down, and moves front to back. Simple, elegant, and original. Hyper Racing was the first to put adjustable steering in 600cc Sprints.
• Adjustable Seat Height Option: Allows 7" adjustment in seat height, which is good for drivers who are still growing. Adjustable upper seat clamps make mounting the seat much easier for different height and size drivers.
• Adjustable Upper Seat Belt Bar: Enables the belt cross over bar to be mounted in the exact right position, level with the driver’s shoulders.

WE DEFINE THE INDUSTRY STANDARD

Hyper Racing was the first to market with all of these trend setting designs. And there are plenty more to come!

• Innovative Radiator Design: Flow through bottom up design keeps the heat off the driver, and off the engine. Cools better than rear mount or sprint car style front mount.
• Tri-Lock Deluxe Splined Steering Hub: This milestone improvement is included on every chassis. Eliminates the loose feeling and less secure steering wheel, lasts for years and requires no welding!
• Deluxe Chassis Harness: Included on the race ready cars. Wiring is simple and clean.
• Quality Components: Brands like Wilwood, Keizer, Simpson, ARS, UltraShield, and our own HBS machined components populate the landscape. We do not take shortcuts. These components enable the Hyper Chassis to last a long time, provide the ultimate in performance, and keep the resale value high.
• Fuel Forward Tank Tail and Bladder System was designed by Hyper Racing to keep the polar moment of inertia low. Now it is used by all of the other builders, and has become the industry standard.
• HBS Left Front Brake Caliper features two pistons and no spacer shims. Hyper Racing designed and developed from scratch in 2010. We're not trying to brag, but it's just as much fun to win the chassis development race as it is to dominate on the racetrack.

HERE’S WHY DETAILS MATTER

• Longer Rear Axles: We offer longer rear axles than anyone else. A 55” long 1-3/4” and a 57” long 2” rear axle are available. You can still get the shorter axles if you like. The longer axles offer the ability to change to a less offset right rear wheel (7 on 6, or 7 on 7) for better tire wear and increased traction in certain situations. They also give the flexibility to increase your rear width by moving the right rear and/or left rear wheel out.
• Torsion Rack Position: Right rear torsion rack is moved to the right 3" to allow the use of a straight and strong torsion arm.
• Exclusive Shock Packages: We work with all major shock manufacturers to develop specific shock valvings designed for our chassis. What works on a Z-link chassis or other manufacturers' chassis will not work on our wishbone chassis. Our chassis is very unique and requires different shock valving.
• 4-Piston Caliper: The Wilwood GP320 4-piston caliper is standard on our chassis. This caliper was purpose built as an upgrade over the dual piston caliper to provide increased pad size. This will help reduce rotor warping and increase braking performance.
• Controlled Torsion Arm Angles: Uniquely designed bearing carrier plates use longer shackles and multiple holes that will allow the shackles to be raised and lowered. Instead of raising or lowering the car by adjusting the torsion stop, the ride height can be changed by moving the shackle to a higher or lower hole in the bearing carrier plate. This allows the torsion arm angle to remain constant while the whole car, or one corner is raised or lowered.

ALWAYS STRIVING FOR IMPROVED SAFETY

• Cage Gussets: The long unsupported section of the roll cage is now supported by gussets for added safety.
• Strength Through Triangulation: X-bracing and proper crash zone design helps increase safety.
• Superior Quality Materials: We source only high-quality all American or German made 4130 chromoly tubing to be used to make the structural members of the X11/X7 frame.
• Expertly fabricated and TIG welded all the way around by our professional Welding and Fabrication Team in Lewisberry, Pennsylvania.
