Offroad racing buggy - How are the new rims supposed to fit?

You want to drive a larger rim, but can't find a way to adapt your desired rim or don't know if it's even possible?

Then you are right here on our blog. 

Here you can find out more about how we can help you with your problems. Here you can learn more about customer projects that had the same problems as you and how they were solved.

Below you can see our process for a customised bolt circle adapter production.

Project

Hans-Georg asked us if it would be possible for us to make adapter plates/hole circle adapters as a special production for an off-road racing buggy, which would make it possible to drive two different types of rims with different hole circles. First of all, of course it was possible for us, more about that later?

Planning

First of all, there is always the question of whether you have a drawing or sketch, or on the basis of which dimensions we should produce. The special thing about this project was that two different bolt circles were needed at the front and the back.

Hans-Georg was able to answer these questions quickly and sent us a CAD drawing and told us that the bolt circle adapters should be made of aluminium!

After we received the CAD drawing, we could start with the calculation for the bolt circle adapters and send out the offer!

Drawing

Production

After receiving the order from Hans-Georg, we now mill the bolt circle tuning adapter for the off-road racing buggy to a precise fit. The adapter is then taken to the surface refiner.


A short time later, when the package had been sent on its way, we received super ingenious installation pictures from Hans-Georg - many thanks for that!

The following is the original feedback from Hans-Georg

"The thing with the 2 circles A brand change in racing usually means more than just changing the manufacturer's logos. And as it happens, after the great euphoria about the new one, usually comes the awakening. In my case, the change from Arctic Cat to Yamaha brought a cool new machine into my workshop. Nakich, no spare parts, but a lot of cat parts that suddenly no longer present themselves as treasure but as ballast. What else can you use on the new one? There are a lot of wheels in the warehouse that look like they would fit at first glance. But that's not the case. Offset, rim width and wheel diameter, all OK. Shit, the bolt circle diameter differs by 5 millimetres: 110 for the new ones, 115 for the old ones. Since discreet wheel spacers are the order of the day anyway, the solution to this little problem seems logical and simple. Why not track plates with a double bolt circle? When I asked the specialists at epytec in the Black Forest, they only smiled tiredly. "Make a sketch with your ideas and the necessary measurements, or even better, a proper drawing," after about a month the parcel service brings me cool aluminium rings with lots of holes and threads, which elegantly solve my little problem. Since the wheels to be used have different centre centres, we simply do without this feature altogether. The rims are centred on the rings by cone bolts, and there is nothing to complain about in terms of concentricity, especially for off-road use. A made-to-measure solution, even my TÜV (Technical Inspection Agency) didn't find any regulations that could justify a refusal, thanks to the material report provided by epytec. Everything is OK and thanks to the specialists in Münstertal. Greetings from the East to the South Hans-Georg"
