No...I didnt think it would be necessary since I was going to install 20's on the car and still planning on FI this winter but I wont be tracking it HARD. Just causal driving and tracking it every now and then. I will admit the parts are VERY LIGHT but the 370z parts are already somewhat light, as you know. Also I dont have access to a scale to weigh it each time I swap out a part.![]()
