My buddy takes his BMW to Bullet Performance Engineering in Costa Mesa. The owner Ken was the service manager at Crevier years ago. They prep a lot of cars for aggressive street driving and track driving and the last time I was there they were an authorized Dinan dealer. There are some sick cars there all the time. It's located just off of Bristol and Baker I think.
