Let me just start with this statement that you desperatly need to hear. Street racing is stupid, pull your head out of your ass and relize that shit will only get you or someone else killed. That being said, your not gonna get to much out of the D series with out going turbo. If you truly want to apreciate your car as it is now i would do suspension upgrades. You do more turning in daily driving then you do pedal to metal throttle...er...well maybe not considering your story but anyways youll apreciate the feel having a nice suspension offers.
