What are the torque specs and patterns for my HiPer Wheels?

Center Section – Torque center section bolts with 3/8 ” drive ratchet, maximum 9 – 11 ft-lbs (108 – 132 in-lbs) in a two-stage star or criss-cross pattern.
Bead-Lock Ring – Torque bead-lock ring bolts with 3/8” drive ratchet, maximum 8 – 11 ft-lbs (96 – 132 in-lbs), (NOTE: DO NOT EXCEED TORQUE SPECIFICATIONS)

How can a carbon fiber wheel be stronger than aluminum?

HiPer Carbon Fiber materials yield strength is almost three times higher than 6061-T2 aluminum (CF40 = 44.5KSI compared to 6061-T2 = 16KSI). The low mass of hiper material also allows us to use thicker cross sections, which adds to the strength. Twice the strength is an understatement.

How can a carbon fiber wheel flex without breaking?

Carbon Fiber material has a very high yield strength, which allows it to flex under extreme loading and return to its original shape, just like a spring. 6061-T2 aluminum has a low yield strength, which makes it very easy to permanently deform.

How can a carbon fiber wheel cost the same as aluminum?

Raw Carbon Fiber material costs more and is worth more than aluminum. However, since we use half the weight of material to build a wheel, companies manufacturing cost is not dominated by the cost of the raw material. The cost saving is made up in companies manufacturing efficiency. Much of the cost of aluminum wheels is in manufacturing, i.e. forming, welding, polishing, etc. HiPer has none of those costs. HiPer has the best solution...Go HiPer

What makes the carbon fiber wheels so light?

Weight is determined by material density and the amount of material used. HiPer Carbon Fiber material has a much lower density than aluminum but we use a thicker cross section. On average, HiPer Racing Wheels then are around the same weight of an aluminum equivalent, but is 2-3 times the strength. Company traded equal weight for three times the strength. You win. Go HiPer

What do you mean by modular design?

The wheel is built in 3 basic pieces or modules. There are two wheel halves and one center section. Each module can be purchased separately, allowing the owner to upgrade and replace components individually. Additional modules can be purchased separately allowing you to create your own offsets for your particular race car setup.

Why do the rims look more like plastic than carbon fiber?

Carbon fiber composites come in many forms. The most common form is a translucent epoxy matrix with carbon fiber fabric reinforcement, which produces the woven appearance usually associated with Carbon Fiber. This form of carbon fiber is used to produce very high uni-directional strength but tends to delaminate and may deteriorate with outdoor exposure. Wheels use a form of carbon fiber that is mixed with an opaque nylon resin matrix. The discontinuous carbon fiber reinforcement, looks like plastic because the carbon fibers are hidden under the matrix. This form of carbon fiber is multi-directional in strength and highly impact and weather resistant.

If you scratch a wheel will it break?

Not likely, this form of carbon fiber is much less scratch sensitive than fabric laminate carbon fiber where scratches lead to delaminating. HiPer material is homogenous and will not delaminate. If the scratch is not deep, keep racing... if it is deep, replace the wheel module as soon as you can.

How are the wheels made?

The exact manufacturing process is proprietary. Company are not telling the whole story here, but it is basically a thick wall molding injection molding process.

How can you tell if the rim is damaged internally?

HiPer carbon fiber composite is a homogeneous material, which will not delaminate internally and hence is not subject to “internal damage”.

What does the term “run-out” mean?

The run-out of a wheel is a dimensional tolerance that defines the trueness and roundness of a wheel. High precision wheel like HiPer wheels will have low run-out measuring in the few thousands of an inch.

MX Motocross Questions

I have seen the competitor’s rims with billet centers break at the MX track. Why do you think yours will hold up to MX?

HiPer wheels are a modular design, which uses fasteners to clamp the wheel halves to each side of 6061-T6 billet hub center. This eliminates the heat effect zone caused by welding which tends to weaken the material next to the joint.

I thought the large sidewalls were for cushion?

Riders like the extra cushion the sidewalls provide to help prevent rider fatigue during long moto’s. The fatigue is a result of the suspensions feed back, which is affected by characteristics such as shock setup, suspension geometry, and unsuspended mass. The sidewalls help dampen that feedback. Taking away unsuspended mass will do the same by improving the suspensions response time. HiPer wheels with 18×11-10 tires reduce unsuspended mass by more than 6 pounds. Let your suspension do its job and let the tires do their job.

Sand Dune Questions

What are the best rims for the Dunes?

UTV Beadlock wheels are ideal for your dune driving. We recommend a 4+4 offset front and a 5+5 offset rear on 14?? wheels. This combination will help your steering and acceleration. Many ATV dune riders and drag racers are ordering 9×9 dual beadlocks because of their ability to swap tires without using a tire bead breaking tool. HiPer 10×9, 10×10 and the 9×9 with the 3+6 offset rims are the choice for the jumper and duners who use Sandskate II’s.

TT Tourist Trophy Questions

What does TT stand for?

TT stands for Tourist Trophy. TT is part of the Grand National Series and is much like road racing but with small high speed jumps. The coarse is designed with high speed and low speed right and left hand turns and is usually run on hard packed dirt/clay. TT quads are built light and fast.

Why do your TT rims have dual bead locks when most racers run one or none?

Most racers do not run dual beadlocks for TT because of weight. The weight of a 10×10 .190?? wall aluminum beadlock is astronomical and greatly effects straight-line acceleration and brake wear due to the additional rotating inertia. The wheel weight also affects the suspension tuning, as adding un-sprung weight slows the suspension’s response time. Some Pro’s are running a somewhat ingenious hidden bead retainer which locks the tire on using screws, as they realize that beadlocks are still a necessity. They also realize that a hard bump with a competitor or an obstacle could give them a bent rim and a nice fat DNF for their record. HiPer 10×10 rims solve these problems as they only weigh 6.8lbs (6.5 lbs w/titanium fasteners) while having the much needed dual beadlocks.

XC Cross Country Questions

How do they hold up against rocks?

Designed specifically for the rigors of Cross Country and Desert racing HiPer 9×9 rears incorporate dual beadlocks. The beadlock rings have a tapered edge to deflect off of the rocks or stumps along with counter sunk fasteners, which allow the beadlocks to slide across obstacles without catching. HiPer beadlock rings are designed to absorb the punishment while protecting the inner wheel halves. The inner wheel half is designed to flex, protecting your axels, your quad, and yourself.
