Dear OP,
You can email me directly for more information @
omar@velosdesignwerks.com. Regarding adding a supercharger kit to your 2008 M3 as stated above there have been issues with 08 cars from some SC manufacturers so it is best to do your research before boosting. We have experience with installing a few ESS kits as well as personal experience with other systems on the market. In a perfect world it would be recommended to swap our your bearings before adding a system but I am confident there are systems on the market that work well on a 2008 car. Feel free to email or call with any other questions or concerns.
Best Regards,
