We’re hard at work this weekend, continuing to dive into prototyping our next generation Ultra4 rotor. This all started back with Brad Lovell’s Pro Light, where we prototyped a heat-treated, stainless steel, double disc ground 1/4″ thick rotor. Essentially, an over the top performance rotor that to date, has helped power Brad to two TORC 1st place finishes this year alone, most recently at Crandon. As exciting as this rotor design was, we skipped calculating the costs as in the end, it would likely not make financial sense for an Ultra4. Sure, it works well, but that doesn’t mean another version couldn’t performance just as well at a fraction of the cost.

And now we enter this weekend. Above, you’re getting a glimpse at what we envision our upcoming Ultra4 Pro Series Rotor to be. Steel construction just like our current large diameter brake rotors, but with a new less aggressive, but arguably more effective, combination hole and partial depth slot pattern, finished off with true double disc grinding just as we had done with Brad. In the end, the extra manufacturing will add some cost to our traditional rotor, but it should be reasonable and affordable, especially considering the added advantages for the now blended mix of Ultra4 terrains.

The set we’re finishing up now will go under Jason Scherer’s IFS racer for testing at Glen Helen on July 21st. We’re confident they will performance as well as expected, but in the end Jason’s racer will be the evidence of that.
