Frequently Asked Questions

What diameter are the wheels you offer?

         The Ergonomic wheel is 340mm in diameter and the Dished wheel is 350mm  in diameter.

How "deep" is the Dished wheel?

         The Dished wheel measures 75mm from the outermost face of the wheel to the back of the mounting surface.  The Ergo wheel is flat.  The Dished wheel will typically give more legroom and bring the wheel closer to the driver.

How easy is it to install the hub in my car?  Do I have to cut, drill, or weld?

          These hubs were designed to just bolt in.  They are installed the same way that the original wheel was installed in the car.  No cutting, drilling, or welding to the steering shaft is required with any of our hubs.

Can I use your hub to install another manufacturers wheel?

          No, our hubs were designed to fit either of our wheels, or the Quick Release unit we sell.

What steering wheels fit the Quick Release unit you sell?

          Our Quick Release units have two sets of holes.  One set of holes is drilled to fit our wheels, and the other set of holes is drilled to fit other popular racing steering wheels (MOMO, OMP, or Sparco).  The two bolt patterns are as follows: one set is drilled "six on 74mm" with 5mm screws, and the other set is drilled "6 on 70mm" with 4mm screws.

Can I use your Wheels with my existing hub? 

          Typically no.  Our wheels were designed to fit our hubs or our Quick Release and have the larger "six on 74mm"  bolt pattern.

Can I use your Quick Release with my existing hub?

          Typically no.  Our Quick Release units were designed to fit only our hubs and have the larger "six on 74mm" bolt pattern.

Can I keep my horn?

          Although our systems were designed for use off-road, we have worked with customers to help them keep their horn buttons in the stock location.  A few hubs for certain models have been modified to accept the wiring for a horn, but every car is different.  We do offer a horn button for our wheels, and also the contacts for the Quick Release unit.  Call us to inquire.  We will have a section giving more detailed instructions on the installation of a horn button soon.
