Simulate performance part swaps
This simulator estimates what happens when you transplant an engine, transmission, or chassis package from one car into another. It recalculates headline performance numbers and adds a practical feasibility score so the results are more useful than fantasy build lists.
Use it alongside the comparison tool for stock-versus-stock research, and read our guide to comparing cars if you want a framework for interpreting the output.
