Blue Collar Average Joe 2wd No Prep Street Diesel Truck Class

Welcome to the Average Joe - No Prep Street Diesel Truck Class.

This class was built around the average diesel enthusiast’s ultimate goal for their
truck. Too often, racers are forced to ruin great street trucks just to fit into a race class -
adding cages they don’t want, building laggy turbo setups, running stiff and miserable
suspensions, or sacrificing drivability altogether. The alternative usually ends up being
boring bracket racing or low-excitement Sportsman-style classes.

We wanted to create something different.

The Average Joe class is designed so you can build your dream street truck and still
compete in an intense, heads-up racing class with a strong payout - without turning
your truck into something you hate driving.

This class is meant to simulate how these trucks are actually driven in the real world
and put on display just how effective a well-built street truck can be.

2WD. No prep. Street tires. Leaving from a stoplight. Non-Boosted launches. Leave
from idle.

That’s how we spend 99% of the time driving in our diesels, and that’s exactly what this
class is designed to showcase. How well your truck actually drives.

Winning in this class won’t be about extreme peak horsepower. It will be about:
● Quick-spooling setups
● Linear, controllable power delivery
● Solid tuning
● Driver skill
● 650-750hp range to be competitive

To keep the competition close and accessible, power restrictions and platform-specific
handicaps have been carefully implemented. The goal is to create a level playing field
where 90% of diesel street trucks can realistically compete, without one platform
holding a massive advantage over the rest.

Stop light street truck racing, the way it should be. Non-Boosted 2wd Street Racing
● Non-boosted launch to highlight quick spooling setups
● Non-boost launch is safer in 2wd (should not launch hard or you will spin)
● 2wd no prep rewards better tuning, quicker spool, liner power, and good drivers
● 2wd gives a handicap to lower hp trucks that drive better on the street and
punishes those who build a laggy setup with horrible tuning and giant injectors
that drive like garbage but make a little more power. This allows racers to focus
on winning a race because of a better driving experience. That is literally the
point of this class
