RES Tech: The Tuning FUNdamentals

The Fundamentals of Performance

At RES, we believe a rig is only as good as its setup. While crawling often feels like a game of inches and "slow-and-steady," the underlying physics of your suspension, weight bias, and geometry are what truly separate a trail truck from a podium finisher.

To help you dial in your rig, we’ve curated a collection of elite reference materials. This includes foundational resources like the Hudy Off-Road Setup Guide—originally designed for the high-stakes world of competitive racing, but packed with universal principles that are directly translatable to high-performance crawling. We’ve used these principles for years in racing, drifting and crawling. A knowledge base we’d like to share with our community as we craft and tailor RESources of our own for all of us to enjoy.

In this section, you will learn to master:

• Suspension Geometry: Understanding how oil viscosity, spring rates, and mounting angles change your "climbability."

• Weight Distribution: Managing the Center of Gravity ($CoG$) and Roll Center to prevent mid-climb rollovers.

• Traction Mechanics: How toe, camber, and caster settings affect your steering throw and side-hill stability.

Whether you are building a Class 3 beast or a precision Micro Comp rig, use these guides to move beyond "trial and error" and start tuning with intent.
