I've received lots of e-mails lately asking about steering hubs. Here is some information to address those questions.
Aftermarket steering hubs and steering wheels are one of the best mods for the NSX and one of the best "bang for the buck" mods. A hub and steering wheel will cost between $400-500.
An aftermarket steering hub and steering wheel replace the factory airbag/steering wheel assy. Due to this; this modification is for "off road use only".
ADVANTAGES
-------------------------------------
This mod has several advantages including:
1. Lighter steering assy results in more precise and sharper steering feedback.
2. Smaller diameter wheels allow for precise and quicker steering inputs.
3. Better grip can be achieved when a steering wheels with high grip material is used (ie. suede). etc...
CONSTRUCTION
-------------------------------------
Steering hubs in general are simple devices that connect the steering rack's spindle to the steering wheel. The stock steering wheel/airbag assembly serves the same purpose; however, an aftermarket hub allows you to connect an aftermarket steering wheel. The hubs for the NSX are designed to be used with Sparco, MOMO, OMP, or any steering wheel with the 6 bolt configuration. You can see the steering wheels offered by ScienceofSpeed here: http://www.sparcousa.com/steeringwheels.htm
HORN & CRUISE CONTROL FUNCTIONS:
-------------------------------------
Wires to switches on the steering wheel running from the console could stretch and break from the constant rotation of the steering wheel. Thus, special consideration must be made for electrical switches located on the steering wheel.
The stock steering wheel uses a device called a clock reel for this. The factory clock reel has pins that allow the steering console and steering wheel sides to rotate independently. With this approach, there are no wires to pull or snap from rotating the steering wheel.
TYPES OF STEERING HUBS:
-------------------------------------
There are three types of steering hubs available for the NSX:
1. Fixed steering hub with riggers
“ScienceofSpeed Steering Hub”
The steering hubs are fixed (made to remain attached to the steering column) and are generally made out of steel. They consist of a base that attaches to the spindle, and riggers (support arms) that attach to the steering wheel. In theory, the riggers are designed to collapse in the case of an accident, distributing the force of the impact. The NSX-R, NSX Type-S, and ScienceofSpeed Steering Hub are of this type. It is possible to retain horn functions with this hub, however, these hubs do not work with the factory cable reel. The hubs have a brass ring around the base that connects to the horn button on the steering hub. An interface must be built between the hub’s brass ring and the steering console to complete circuit for the horn button. While I have not seen an NSX-R in person, I believe Honda uses an M8 bolt location on the console to position a spring loaded contact to complete the circuit with the hub’s brass ring.
ADVANTAGES: light, collapsible riggers
DISADVANTAGES: does not work with the factory cable reel
2. Solid fixed steering hub
“TAITEC Steering Hub”
The solid fixed type steering hub is typically machined billet aluminum. The Mugen, GruppeM, Phase, Revolution, and TAITEC hubs are of this type, and have parts sourced from the same manufacture in Japan. These hubs allow the use of the factory cable reel and are made specifically for the NSX. The TAITEC hub, for example, is supplied with the required wires to bypass the SRS light, and connect the horn. In addition, you may wire the cruise control buttons to the steering wheel. Because they are made from a solid piece of billet, they do not have the crumple riggers, and are somewhat heavy.
ADVANTAGES: utilize factory cable reel
DISADVANTAGES heavy, no crumple riggers
3. Quick release, pivot hubs
The steering hubs are designed for race use. These steering hubs either allow quick separation of the steering hub and steering wheel, or pivot upwards to allow quick access in and out of the car, especially helpful when the car is equipped with a roll cage. In general, these steering hubs do not have any type of appropriation for the horn or cruise control buttons.
ADVANTAGES: quick access in and out of the car
DISADVANTAGES: heavy, no crumple riggers, to appropriations for the horn, cruise
