I have taken 266 lbs off of the beast which has made a huge difference.

My list is as follows:-
Seats (92 lbs)
Headers and cat back exhaust:-(70)
Brakes (50)
Cf Bonnet (30)
Wheels (24)

Then there is the light weight battery like you have stated, cf trunk and roof. The next step would be going radical with plexi windows, rear seats removal, adding cf fenders, and replacing parts with those of titanium material.

Hope i helped :M5rev:
What did you do to the seats and brakes. Also, I have the Vorsteiner hood and they said their CF bonnet doesn't really offer any weight savings over the stock hood. Both are already light. What brand do you have?

Regards,

Darren

My car weighs 4,160 lbs with a brand new full tank of gas and without me in the car. The car was weighed on a CAT certified scale The breakdown front to back is as follows:

Front = 2140
Rear = 2020
------
Total = 4160

This weight was measured this past Friday evening.

Thanks,

Darren

That's good to hear. Over a year ago there was quite the discussion on weight, and I weighed my car three times on truck scales, and came up with weights within 10 lbs. What I got on average was 4180 lbs with a full tank, stock tires/wheels and nothing else in the car. I would guess my car is the worst case since I have all the options, including a Blinder M40.

I don't know what the options weigh, but I'll bet the listed 4012 "curb weight' for the M5 is without any options. Sunroof, high end stereo, ventilated comfort seats, pdc, nav, rear side airbags, Sirius radio, heated rear seats, sunshades, and even full leather probably add the additional 170 lbs.
Mike,

I think you're right on. I have every option available for the model year 2006 as well. The only difference is I'm using the Neez QD7 wheels which offer a small weight savings, race cats which weigh a few pounds less than stock secondaries, and the Dinan exhaust which offers another small weight savings.

I didn't clean out my trunk entirely which had 2 quarts of oil, roll of painters tape, car cleaning stuff and an umbrella. Probably added another 10 lbs or so collectively.

Cheers,

Darren
