MOD PLATE EVERYTHING! Your car is cleaner than my GTR and I get very little attention. Remove the boost controller, its a defect. Get a mod plate for the exhaust and the suspension at the bear minimum. If you need a mod plate guy to come to you, let me know and I'll get the number of the guy that did mine. He was cheap and knew all the rules.
I hate cop attention as much as the next guy, we need to stand together and show these dream boats cops we WILL NOT GO AWAY!
