Torsional Rigidity Analysis of Modified Porsche Boxster Chassis

I'm reengineering a Porsche Boxster chassis and need a detailed comparison of its torsional rigidity against the standard model.

Requirements:
- Use Finite Element Analysis (FEA) for assessment
- Provide numerical values for rigidity comparison
- Work with my detailed modification plans

Ideal Skills & Experience:
- Expertise in FEA software (e.g., ANSYS, SolidWorks)
- Experience with automotive chassis analysis
- Strong background in structural engineering and mechanics

Please include relevant experience in your bids. Looking forward to your proposals!
