Performance Software

CarBahn’s performance software is designed to deliver reliable “Smooth Power” meaning the software is calibrated correctly by using a safe approach to power adjustment. Excessive torque will break the tires loose, overload the engine and ruin the drivetrain. To reach optimum power, the software is easily combined with our high-performance intercoolers/heat exchangers and turbos. Call (650) 495-0421 or Learn More >
Suspension Tuning

Steve Dinan is famous for road car suspension systems that not only handle better than the competition they ride better as well. CarBahn designs their own suspension systems paying careful attention to spring, damping and anti-roll bar relationships as well as bushing deflection and suspension geometry to make a truly superior system.
