Yea I was just listing what is possible  As someone who tracks his car quite often, I would personally never choose CCB no matter how light they are. I still think the blue brakes are pretty good for what they are and they weigh 35lbs less than the silver M2C brakes. Regardless, your calculation (-60lbs) is probably what's gonna end up happening  I would still add a lithium battery to it tho if BMW doesn't do it from factory. For about $700, you can save another ~48lbs with Antigravity RS-30 battery for instance (combined with CF hood, it shouldn't affect the weight distribution by that much). |
For tracking, you want to save as much as possible on rotation mass ( inertia is big for breaking, accelerating, steering feel ) including wheels.
With good forged wheels and CCB you can save about 70lbs total
