Installation summary

This suspension upgrade requires advanced DIY skills and is best suited for experienced mechanics working in a fully equipped garage. The five-hour installation process involves replacing both front and rear control arms with the M-spec components, which will add approximately 0.75 degrees of negative camber to your front end. You will need specialized spring perch tools if you are adjusting ride height on coilovers, and a professional four-wheel alignment is strictly required immediately following the installation to correct handling geometry. The most important thing to watch out for is fully pre-loading the suspension bushings at your new resting ride height before final torque-down to prevent premature bushing failure.
