Quick Guide
  • screw drivers suspension parts are the required foundation for placing wheels on a vehicle.
  • Six suspension types are listed: small, street, dirt, big, motorcycle, and their specialized variants.
  • Choose by build role rather than assuming one suspension fits every vehicle design.
  • Check wheel placement before finalizing a chassis, because suspension determines where wheels can attach.
  • Use a test-first setup to catch compatibility and layout problems before committing resources.

screw drivers Suspension Basics

The screw drivers suspension system is built around one central rule: suspensions are the only parts on which wheels can be placed. That makes them a structural requirement for any vehicle that uses wheels. A chassis may provide the shape of a build, but the suspension establishes the connection point between the vehicle body and its wheels.

The available list includes six parts:

  • Suspension Small
  • Suspension Street Small
  • Suspension Dirt Small
  • Suspension Street Big
  • Suspension Dirt Big
  • Suspension Motorcycle

The names provide useful planning signals. “Small” and “Big” identify broad size categories, while “Street” and “Dirt” indicate specialized variants. Motorcycle suspension is separated into its own category and should be treated as a dedicated option rather than a direct replacement for standard vehicle suspension.

Build Foundation

Place suspension parts early in the design process. Since wheels attach only to suspensions, they should guide the chassis width, wheelbase, and overall vehicle footprint.

Suspension Types and Selection Logic

The suspension list is easiest to understand when divided into three groups: standard, street, and dirt. The standard Suspension Small part is the neutral reference point. Street and dirt versions are more specialized, while the big variants suggest a larger build scale.

The source material does not provide numerical attributes, handling ratings, durability values, or unlock requirements for individual parts. Therefore, the safest way to choose is by matching the part name to the intended build instead of inventing performance rankings.

Small Builds

  • Suspension Small
  • Suspension Street Small
  • Suspension Dirt Small
  • Use when compact proportions are the priority.

Big Builds

  • Suspension Street Big
  • Suspension Dirt Big
  • Use when the vehicle concept calls for a larger suspension category.
  • Confirm spacing before completing the body.

Motorcycle Builds

  • Suspension Motorcycle
  • Treat as a specialized motorcycle option.
  • Plan the frame and wheel arrangement around its intended form.

Small, Street, and Dirt Variants

A small suspension is a logical starting point for compact vehicle concepts. The street and dirt versions should be selected when the build identity matters. A road-oriented design can begin with a street-named part, while an off-road concept can begin with a dirt-named part.

The “big” versions follow the same distinction but target larger designs. Avoid mixing part categories casually during the first build pass. If a vehicle starts with a small layout, switching to a big suspension may require changes to the body, wheel spacing, or supporting structure.

Avoid Unsupported Rankings

No reliable source data establishes a fastest, strongest, or highest-rated suspension. Treat the names as category guidance and test the physical fit of each part in your own build.

Step-by-Step Wheel Setup

A stable build begins with the suspension rather than the decorative bodywork. Follow this process to reduce wasted construction time and make troubleshooting easier.

1

Define the Vehicle Shape

Decide whether the project is a compact vehicle, a larger vehicle, an off-road concept, a street-focused design, or a motorcycle-style build. This gives you a starting category without assuming hidden statistics.

2

Select the Matching Suspension

Choose the closest listed part: small for compact designs, big for larger designs, street for road-oriented concepts, dirt for off-road concepts, or motorcycle for a motorcycle-style frame.

3

Place the Suspension Before the Wheels

Build the core layout around the suspension positions. Because wheels can only be placed on suspensions, their locations should determine the basic wheelbase and chassis footprint.

4

Attach and Inspect the Wheels

Add the wheels to the suspension parts, then inspect spacing, alignment, and body clearance. Fix the foundation before adding cosmetic components.

5

Refine the Chassis

Once the wheel arrangement is stable, add the remaining structure. If the body conflicts with the wheel area, adjust the chassis instead of forcing an unsuitable suspension category.

The most important part of this workflow is the inspection stage. A vehicle can look correct from above while still having poor spacing or an awkward wheel connection. Test the foundation from multiple angles before investing time in visual details.

5Add the bodyChassis does not interfere with wheel placement
Reliable Workflow

A suspension-first workflow keeps the most important attachment points visible. Finish the wheel foundation before adding armor, panels, or decorative sections.

Troubleshooting and Build Optimization

When a vehicle does not look or function as intended, check the suspension layout before rebuilding the entire design. Since suspensions control wheel placement, many apparent chassis problems begin with the wrong size category or an unsuitable variant.

Use these checks during testing:

  • Confirm that every wheel is placed on a suspension.
  • Compare the suspension category with the intended vehicle size.
  • Look for body pieces that block or crowd the wheel area.
  • Check whether street or dirt naming better matches the build concept.
  • Reposition the chassis before changing several parts at once.
  • Test the basic wheel layout before adding visual complexity.

A common mistake is starting with the body and trying to fit suspension afterward. This can create narrow wheel wells, uneven spacing, or a frame that does not match the selected part. Building from the suspension outward gives you a clearer reference for every later component.

ProblemLikely CauseRecommended Fix
Wheel cannot be placedNo suspension at the intended positionAdd or reposition a suitable suspension
Wheels sit too close togetherCompact layout used for a larger conceptTest a big suspension category
Body crowds the wheelsChassis was designed before wheel placementMove the body around the suspension points
Build lacks a clear roleStandard and specialized variants were mixed without a planChoose street, dirt, or standard as the design theme
Motorcycle frame feels oversizedNon-motorcycle parts shaped the foundationRebuild around Suspension Motorcycle
Troubleshooting Order

Change one variable at a time: first suspension position, then wheel placement, then chassis shape. This makes the source of a problem easier to identify.

Practical Comparison Framework

The best suspension is not a universal ranking choice. It is the part that supports the intended scale and style of the vehicle. A compact dirt design and a large street design have different starting requirements, even if both use four wheels.

Scale

Compare small and big categories before placing the chassis.

Purpose

Use street or dirt variants when the build has a clear environment or role.

Attachment

Confirm that each wheel has a valid suspension connection.

Iteration

Test the foundation before expanding the body or adding detail.

Suspension Planning Checklist

Use this checklist whenever you begin a new vehicle project or revise an existing wheel layout.

Essential Suspension Checks:

  • Choose small, big, street, dirt, or motorcycle based on the planned vehicle concept
  • Place suspension parts before building the main chassis
  • Attach every wheel to a suspension part
  • Inspect wheel spacing and body clearance from multiple angles
  • Test the foundation before adding decorative or secondary components

Final Design Tip

Keep a simple test version of your vehicle before making a detailed build. A basic frame makes suspension spacing and wheel placement much easier to evaluate.

Suspension FAQ

Q: What do suspensions do in screw drivers?

Suspensions are the only parts on which wheels can be placed. They provide the essential wheel attachment foundation for vehicle builds.

Q: How many suspension parts are listed?

The listed parts are Suspension Small, Suspension Street Small, Suspension Dirt Small, Suspension Street Big, Suspension Dirt Big, and Suspension Motorcycle.

Q: Which suspension is best for a street vehicle?

Start by testing the street variant that matches the vehicle scale: Suspension Street Small for a compact concept or Suspension Street Big for a larger concept. The available reference does not provide numerical performance rankings.

Q: Can I place wheels directly on the chassis?

No. The suspension category is specifically identified as the part type on which wheels can be placed, so the chassis should be built around those attachment points.

Key Answer

When planning any wheeled vehicle, select the suspension category first, attach the wheels second, and shape the chassis third.
