Introducing the “Super Stock” Class

While I’m not sure of the interest level in this class, several drivers have expressed interest in a slightly more advanced set of rules to enable more tuning and flexibility in building cars.

Our Super Stock class is based on the 2022 HOPRA SUPER STOCK rules but has two key differences:

    1. HOPRA restricts motor and traction magnets to stock Ceramic-only material and does not allow Compression-molded Polymer (Level 4) magnets in this class. We allow standard V-SPEC Level-4 magnets.
    2. HOPRA does not, however, have any restrictions on armature bushings, gearing, axles, or wheels and tires. This means HOPRA rules allow dual-compound tires, we don’t. Only silicon slip-on tires are permitted.

Kevin Webster has a bunch of HOPRA-legal Super Stock cars, which he and I tested extensively. The general consensus was that the HOPRA car was not significantly different than our current Viper V-SPEC (SPEC-RACER) class and forcing interested drivers to purchase expensive ceramic-grade magnets for these platforms would be a burden to many of our drivers.

Due to the cost of dual-compound tires and the lack of interest in purchasing them, we decided against allowing dual-compound tires—for now. In our testing, dual-compound tires produced about a half-second faster lap times.

So, why setup and race a Super Stock car? Well, one reason is that there are a few more tuning options available in this class:

      • Open gearing choices, unrestricted.
      • Adjustable brush tension (on brush-barrel type chassis’)
      • Any material for armature bushings, except ball-bearings.
      • Many competitive chassis options: BSRT G3/G3R/G3RS/G3RSB, Mattel/Tyco 440-X2, Micro Speedworks T+, Slottech T1/T2/T3
        and T1X, Wizzard-Patriot P2/P3/Scorpion/Storm/Storm CH22/Fusion, Viper V1 (V-SPEC).

Bottom line, this class provides a bit more speed and tuning flexibility to those drivers interested in moving up a notch or two in tuning ability and options.

We’ll see where this class goes. Right now, only a couple of active drivers have these cars ready to race. That said, you can actually just run a good stock Viper V-SPEC and do fine on most tracks. The gearing options are pretty simple, all you need are a couple of spare rear axle assemblies with lower or higher gearing and swap them out to see what works best on the particular course you’re running on.

The other tuning options are a bit more nuanced but also very useful.

Okay, shut up and drive!
