sub3000 pounds possible for a street/track car?
I am looking into getting a Z4mC. Mostly will be driven on weekends with about 5-10 days on the track.
I am not looking for more power. But looking to reduce weight. I'd love to get the car sub 3000 pounds without doing a full race build. I searched this forum, but honestly there isn't much from a weight standpoint. It is either full race build to get to 2500 or like 50 pounds from seats. Anyone know the road to 3000 or below pounds in this car and keep it streetable?

Light wheels, big brake kit with forged alu calipers, lithium battery, race buckets, removing the interior behind the seats will get you sub 3K lbs if you don't try to put in a half-cage. With a decent half cage and aero, you'll be closer to 3,150 lbs like my track+street Z4MC.

I kept my speakers and AC too, so I can listen to podcasts in cool comfort to and from the track. |

I have thought about ditching the AC since that would be a quick 30-40 pounds. 90% of the time I am windows down but there are those days though when it comes in so handy. I really would like to find a way to drop another 50-100 lbs but i fell this would be expensive. I am watching the MCast and his Goke GT4 kit to see how much weight if any that drops. If it drops another 20-30lbs and the body panels are 10mm wider to accommodate bigger rubber that might be the next step.

The last few pounds are hard... really hard... and probably expensive.. :shrug:
Its especially dis-hearting when you add the weight back in in form of a cage...

There’s a weight reduction thread that many of us in this thread provided details and corner balance weights in.
https://www.zpost.com/forums/showthr...=800067&page=3 In short, easy to get to with everything mentioned about (bbk not necessary) but once you add a roll bar in it’ll get you just over 3k again. Keep in mind that a prepared e46 race car (HS or HP with BMW Club Racing) has a minimum weight of 3,142lbs With driver so ~3k lbs is not a bad place to be. |
