Baja SAE Suspension CAD Design
Budget: $10 – $30 USD
Project Overview:
We are designing a Baja SAE off-road vehicle and have finalized our front suspension kinematics using OptimumKinematics. We need an experienced Mechanical Design Engineer / CAD Designer to create a detailed, manufacture-ready 3D CAD model of the front suspension geometry based on our exact coordinate data, including specific spring and damper attachment hardpoints.
Suspension Type: Double A-Arm (Wishbone) Suspension with separate shock/spring assembly and steering tie-rods.
Technical Specifications & Hardpoints Data (in mm):
The design must strictly adhere to the following coordinate points [X, Y, Z] extracted from our kinematics setup:

3. Suspension Spring Rates:
Left & Right Spring Stiffness: 15.000 N/mm
Scope of Work & Deliverables:
1 A-Arms Design: Design structural tubing/plates for upper and lower A-arms based on the hardpoints.
2 Upright (Knuckle) Geometry: Design optimized uprights connecting the ball joints, steering tie-rods, and wheel hub mounts.
3 Shock Absorber & Spring Integration: Correctly integrate mounting tabs/clevises on both the chassis side and the lower/upper arm based on the precise Spring/Damper Attachment coordinates provided.
4 Final Assembly & Source Files: Provide fully constrained assembly files along with native source files (preferably SolidWorks or Autodesk Inventor) and universal formats (STEP/IGES).
Requirements:
Proven experience in automotive, motorsport, or Baja SAE/Formula SAE suspension design.
Strong understanding of weldments, rod ends, and shock tabs manufacturing constraints.
