Screw Drivers Vehicle Builds
From rusty carriages to championship racers — build guides for every skill level.
Vehicle building is the core of Screw Drivers. Every race is won or lost in the garage, and understanding how engines, gears, axles, and suspension work together is the key to domination. This hub collects every build guide on the wiki so you can find the right design for your skill level and goals.
Build categories
Beginner Builds covers your first working vehicles — simple, reliable designs that teach you the fundamentals without overwhelming complexity. These builds focus on stability and ease of use rather than raw speed.
Once you have the basics down, Speed Builds pushes into high-performance territory with multi-engine setups, optimized gear ratios, and lightweight chassis designs built for podium finishes.
The Transmission Guide is essential reading for anyone who wants to understand how gear ratios actually work in the game. It covers 2-step and 3-step shifts, torque multiplication, and how to avoid duplicate ratios that waste power.
Key building principles
Every vehicle starts with a chassis. From there, you add an engine, connect it to gears via axles, and attach wheels through suspension. The order matters: gears closer to the engine reduce speed but increase torque, while gears closer to the wheels do the opposite.
Weight is critical. A lighter car with a modest engine will often outperform a heavy car with multiple engines. Test changes one at a time so you can measure the effect of each modification.
Tuning and optimization
Once your basic drivetrain works, fine-tuning separates good builds from great ones. Adjust suspension stiffness to handle different track surfaces. Experiment with wheel sizes — larger wheels reach higher top speeds but accelerate slower. Balance your gear ratios so you never hit the rev limiter on straightaways.
Pay attention to center of gravity. A lower center of gravity improves cornering stability, while a higher one can cause rollovers at speed. Place heavy components like engines low and central when possible.
Race-specific builds
Different races demand different setups. Tight circuits with many corners favor nimble, lightweight builds with strong acceleration. Long straightaway tracks reward top speed and aerodynamic efficiency. Check the Monarchs hub for boss-specific build recommendations tailored to each opponent’s strengths and weaknesses.

Frequently Asked Questions
Quick answers to the most common questions.
What is the best beginner build?
Start with the default chassis, add an Electrix-180 motor, two medium gears, and four small rubber wheels. This simple setup handles early career races well. See [Beginner Builds](/builds/beginner-builds/).
How important is weight?
Very important. Lighter vehicles accelerate faster and handle better. A 200kg car with one engine often beats a 600kg car with two engines.
Should I use electric or combustion engines?
Electric engines are simpler and great for beginners. Combustion engines offer more power at higher tiers. See [Engines](/parts/engines/) for comparisons.
How do I fix duplicate gear ratios?
Duplicate ratios waste power because two gears spin at the same speed. Rearrange your gear chain so each step produces a unique ratio. The [Transmission Guide](/builds/transmission-guide/) explains how to calculate and avoid duplicates.
What wheel size should I use?
Small wheels accelerate faster and suit tight circuits. Large wheels reach higher top speeds for long straightaway tracks. Medium wheels offer a balanced all-around choice for mixed courses.
