Focus Sim Racing FSR One Twenty Sim Racing Chassis
FSR One Twenty Aluminum Sim Racing Chassis
The FSR One Twenty is our most popular aluminum profile sim racing chassis, designed for drivers who want a rigid, clean, and highly configurable foundation for a serious simulator.
Built around 40x120 black anodized aluminum extrusion, the One Twenty is engineered to support modern direct drive wheelbases, high-force pedal systems, and the accessories that come with a more advanced sim racing setup.
Instead of approaching the chassis as a collection of generic extrusion and brackets, we designed the One Twenty as a complete system. Precision-drilled profile, CNC-machined aluminum components, proprietary cup washers, and multiple wheelbase mounting options help simplify the build while giving the finished simulator a cleaner, more intentional appearance.
Built for Modern Sim Racing Hardware
The FSR One Twenty is designed around the forces generated by today's direct drive wheelbases and advanced pedal systems.
- Supports high-torque direct drive wheelbases
- Designed for load-cell, hydraulic-style, and active pedal systems
- Compatible with shifters, handbrakes, button boxes, haptics, and other simulator accessories
- Rigid aluminum construction helps reduce unwanted movement under heavy steering and braking loads
- Highly adjustable layout allows the driving position to be configured around the driver and hardware
Wheelbase compatibility depends on the mounting configuration selected. If you are unsure which option is correct for your wheelbase, contact Focus Sim Racing and we can help confirm fitment before ordering.
Multiple Wheelbase Mounting Options
The One Twenty can be configured around different wheelbase platforms and mounting styles rather than forcing every wheelbase onto the same generic mounting solution.
- Compatible with the Focus Side Mount Pro ecosystem
- Supports modular Focus front mounting plates for select wheelbases
- Available with compatible wheel deck, front-mount, and direct side-mount configurations depending on hardware selection
- Designed to support changing wheelbase hardware without replacing the complete chassis
This modular mounting approach allows the chassis to evolve with your simulator as your hardware changes.
Purpose-Built Pedal Mounting System
The One Twenty uses CNC-machined aluminum pedal risers with indexed adjustment slots, creating a rigid and configurable mounting structure for a wide range of pedal systems.
- Adjustable pedal position and angle
- Indexed adjustment slots make repeatable setup easier
- Ball-bearing T-nuts help simplify adjustment and installation
- Designed for traditional load-cell pedals through advanced active pedal systems
- CNC-machined aluminum construction provides a strong mounting structure without unnecessary bulk
Clean, Simplified Chassis Construction
A typical aluminum profile chassis can require a large number of external corner brackets, bolts, and individual pieces. The One Twenty uses precision-drilled extrusion, CNC-machined aluminum components, and purpose-built hardware to simplify the structure and reduce unnecessary visible hardware.
- Bracket-free main chassis construction for a cleaner appearance
- Precision-drilled extrusion reduces reliance on external corner brackets
- 13mm CNC-machined aluminum rear plate ties the rear of the chassis together with a clean, rigid connection
- CNC-machined aluminum pedal risers replace generic pedal mounting brackets with a purpose-built solution
- Focus proprietary cup washers create a cleaner recessed hardware finish
- Fewer unnecessary brackets and fasteners help simplify assembly
- Maintains the adjustability and modularity expected from an aluminum profile chassis
Designed to Grow With Your Simulator
The FSR One Twenty is designed as a platform rather than a fixed cockpit. Start with the hardware you need today and expand the simulator as your setup evolves.
Compatible Focus Sim Racing accessories and configurations include:
- Integrated and freestanding monitor mounting solutions
- Single-screen and triple-screen configurations
- Shifter and handbrake mounting
- Keyboard and mouse accessories
- Dropped Floor Pan
- Electronics Management Tray
- Complete Clean Install Kit
- PC Shelf
- Additional controls, haptics, motion hardware, and simulator accessories
Designed & Manufactured in Southern California
The One Twenty is designed around the same types of simulators we build every day. That gives us firsthand experience with the frustrations that come from difficult assembly, excessive hardware, poor component access, complicated cable management, and changing equipment requirements.
Those experiences directly influence the chassis. From the simplified main structure to the CNC-machined pedal risers, rear plate, wheelbase mounting system, and expanding accessory ecosystem, the One Twenty is designed to make the simulator easier to build, easier to service, and easier to upgrade.

A Foundation Built for the Long Term
A good simulator chassis shouldn't need to be replaced every time the hardware changes. The FSR One Twenty combines rigid 40x120 aluminum profile, CNC-machined structural components, configurable wheelbase and pedal mounting, simplified construction, and a growing accessory ecosystem into a chassis designed to support both your current setup and the upgrades that come next.
Clean construction. Serious rigidity. Built to evolve.
Cosmetic Finish Notice: Aluminum extrusion may have minor cosmetic scratches, handling marks, or surface variations from manufacturing, cutting, packaging, or shipping. These do not affect fit, function, or structural integrity.
Need help choosing a mount?
Universal Flat Plate
Best for most bottom-mounted direct drive wheelbases. This is the simplest and most flexible mounting option for many common setups.
Side Mount Pro Modular Edition
Our premium side-mount option with added rigidity, adjustability, and front-mount capability. This mount works with both newer and older Fanatec wheelbases and can also accept compatible front mount plates for front-mounted wheelbase setups.
Side Mount Pro MOZA R21/R25 Edition
Designed specifically for MOZA R21 and R25 wheelbases, giving those bases a cleaner and more direct mounting solution.
Side Mount Pro SIMAGIC EVO Edition

FSR One Twenty vs Other Aluminum Chassis
There are several strong aluminum profile chassis on the market. The difference with the FSR One Twenty is the complete platform approach. Instead of buying a generic frame and figuring out the rest later, the One Twenty is designed around clean construction, dedicated mounting options, FSR accessories, showroom support, assembly options, and a long-term upgrade path.
If you want a rigid chassis that can grow with your hardware while still looking clean and intentional, the FSR One Twenty gives you a professional-grade foundation backed by real sim racing support. For customers building an even larger, motion-focused, or top-tier simulator, the FSR One Sixty is available as our flagship chassis platform.
Are FSR Accessories Universal
FSR chassis accessories are designed first around the FSR chassis platform. Some parts may fit other aluminum profile rigs, but compatibility with third-party chassis can vary. For the cleanest fit, best hardware integration, and full upgrade path, we recommend building around the FSR One Twenty platform.
