- 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.
| Suspension Part | Category Signal | Best Planning Use |
|---|---|---|
| Suspension Small | Compact standard part | Small vehicle concepts |
| Suspension Street Small | Small street variant | Compact road-focused builds |
| Suspension Dirt Small | Small dirt variant | Compact off-road concepts |
| Suspension Street Big | Large street variant | Larger road-focused builds |
| Suspension Dirt Big | Large dirt variant | Larger off-road concepts |
| Suspension Motorcycle | Motorcycle-specific part | Two-wheel or motorcycle-style builds |
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.
| Build Goal | First Option to Test | Alternative | Main Check |
|---|---|---|---|
| Compact general vehicle | Suspension Small | Specialized small variant | Wheel attachment and body clearance |
| Small street vehicle | Suspension Street Small | Suspension Small | Proportion and road-build layout |
| Small dirt vehicle | Suspension Dirt Small | Suspension Small | Space around the wheel area |
| Large street vehicle | Suspension Street Big | Small street variant | Chassis scale and wheelbase |
| Large dirt vehicle | Suspension Dirt Big | Small dirt variant | Clearance and body coverage |
| Motorcycle-style vehicle | Suspension Motorcycle | None listed | Frame shape and wheel arrangement |
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.
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.
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.
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.
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.
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.
| Step | Required Action | Completion Check |
|---|---|---|
| 1 | Choose a vehicle category | Intended size and role are clear |
| 2 | Pick a suspension part | Part name matches the planned build |
| 3 | Establish wheel positions | Wheelbase is visually consistent |
| 4 | Attach wheels | Every wheel uses a suspension |
| 5 | Add the body | Chassis does not interfere with wheel placement |
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.
| Problem | Likely Cause | Recommended Fix |
|---|---|---|
| Wheel cannot be placed | No suspension at the intended position | Add or reposition a suitable suspension |
| Wheels sit too close together | Compact layout used for a larger concept | Test a big suspension category |
| Body crowds the wheels | Chassis was designed before wheel placement | Move the body around the suspension points |
| Build lacks a clear role | Standard and specialized variants were mixed without a plan | Choose street, dirt, or standard as the design theme |
| Motorcycle frame feels oversized | Non-motorcycle parts shaped the foundation | Rebuild around Suspension Motorcycle |
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
Quick Reference Table
| Question | If Yes | If No |
|---|---|---|
| Is the vehicle compact? | Test a small suspension | Consider a big category |
| Is the design street-focused? | Test a street variant | Keep the standard or dirt options in consideration |
| Is the design off-road focused? | Test a dirt variant | Compare against a standard or street layout |
| Is the build motorcycle-style? | Test Suspension Motorcycle | Use a standard vehicle category |
| Are wheels ready to attach? | Place them on the suspension | Rework the foundation first |
The six listed suspensions give builders a clear starting framework, but the part names should not be treated as a hidden stat sheet. Use them to organize the design, then validate the actual result through placement and inspection.
For the canonical part list, see the Suspensions article on the Screw Drivers Wiki.
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.
When planning any wheeled vehicle, select the suspension category first, attach the wheels second, and shape the chassis third.
