It's pretty easy to lose weight from the back of the car, but I always wonder what that would do to the balance of the car.
You get a titanium exhaust, plastic/CF trunk, Mini battery and you have a lot of weight out the back of the car.
Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."
