I have (and had at the time of weighing) one carbon bucket in the car. That weighs 6kg ish plus a bit extra for runners and mounts.

No not me. Very unlikely that those guys would get anything wrong with their scales etc, always heard great things about them.

There's a fair saving to be had by going to a manual mech I think.

Ok, in Sweden or Europe there’s lots of manual seat M’s, so is mine. Manual with heating.
Will weigh them when I renew the pads!

Bugger, that's the first mistake in my Z4 book then

I agree that low 1300's would be amazing! Leather trimmed Recaros buckets are going to be my next purchase which should hopefully help drop 40kg?

Sounds about right. More if you get the CF pole positions but they are crazy money.

The seats in the new Alpine look amazing and are only 13kg each:

But I suspect that if you find the equivalent seat (SPS?) direct from Sabelt it'll make the Recaros seem cheap.

They are indeed lovely! As you say I bet they are a few quid!!

I think I'll go spg or pp but standard and not carbon! I think they are around 7 or 8kg from memory?

Hmm not sure who it might have been then! But yes I they are excellent, great setup and knowledgeable guys

Interestingly. this months EVO (April!) covers differences in manufacturers claimed vs actual weights. Don't know if John Barker was reading this thread but he used a Z4MC as a case example. He says the DIN kerb weight is 1420kg which includes all the fluids and 90% full fuel. This is the one they quote in the mag although they point out how mostly the figure they measure is higher than claimed. The EU kerb weight is 1495kg which is the DIN plus 75kg for driver/luggage. This is the one declared for emissions testing.
The article talks about the new WLTP based figures for economy/emissions testing which attempts not only to expose Turbo engines achieving unrealistic results through managing to stay off boost but also exposes some manipulation around weight where when several "trim" options exist for a given model the one with the lowest weight (less options) and smaller tyre (less drag) would be used in the past for testing. Interesting read anyway.

Saw that too - very interesting, even though it was a short article and they ruined it with a picture of a smug German man in a LHD Z4M. They quoted 1379kg “dry kerb weight” (no fuel) and an estimated “dry shipping weight” (no fluids) of 1340kg.

Good little piece I thought.

Bump for those who don’t subscribe to Evo. The article is available online now: www.evo.co.uk/features/21040/what-is-ke ... -car-weigh

Anybody else get their M weighed recently? I just noticed that the article says that when a manufacturer quotes “dry weight” it doesn’t even include oil or battery acid, which renders it totally pointless/misleading for the consumer.

ill try and get mine done within 2 weeks and report back....

Update planning to take this tomorrow morning!!!

LOL!!! ive been looking a ways to drop the figure alittle but i dont want to cheat... so the car is going with half a tank of fuel and the compressor in the trunk , lets see, ive gained weight in the engine but lost weight in quite a few significant areas!!

I was more than a little surprised last week when my son purchased a 2010 TTRS , it weighs less than a Z4M
i would have assumed with its proper seats , electronic front diff + quattro + 19s with 255 35 rubber x 4 & Audi not exactly known for weight saving that it would have outweighed the Z by some margin then again those stock backboxes , they weigh like a tank of fuel
