Lol. People buy a 2 ton car and can actually say with a straight face that they didn’t get the sunroof for the weight

Many forum things don’t pass the “straight face test”.

I’ve always associated exposed CF with Hypercars when CF was god awful expensive. I relate CF body panels to high end cars. The weave is very nice on the G8X. Nothing wrong with a sunroof if you have the headroom. While bmw sunrooms have a bad reputation once they get 10 years old you can mitigate that by clearing out the drain holes more often and ensure the weathstriping stays subtle.

I suspect most of us will sell our cars before we get close to 7-10 year old mark.

every pound of weight shaved counts when you're aiming for good 1/4 time or racing in general at events.

Yes you can also just buy a Civic, gut that and put in a high hp engine, but at the end of the day its not the same thing.

Been to many 1/2 mile /roll racing events. The little amount of weight difference in the roofs will not really make any difference. If your that anal, get carbon breaks/buckets/carbon 18” wheels / rip out the seats/ light weight battery/lose your muffin top and so on. My brother ran the GTR with no seats passenger/rears and was doing same times as with. Maybe more gas on those runs /head wind who knows. Just saying, if you want the sunroof, don’t worry about being slower than the same car without. TIRES would make up way more time than the lesser weight of the roof. So get some R-888’s and have fun

Carbon fiber roof goes with M3 and is standard equipment.

On M2 CF is an option

I had initially ordered a 2022 M3 with a sunroof cancelled it and than settled on a CF roof

I can’t believe this has spanned 5 pages.

Buy what you want.
You’re not going to notice the weight.
You’re not going to detect a big difference in rigidity.
It’s highly unlikely to leak (unless you never use it and let the seals dry out, or park outside and let the drains get all clogged and don’t clean them.
Resale will even out after 5 years or so.

Bottom line, buy what you want.

You might be missing the point of the carbon roof. The M3/M4 are heavy cars that can be tracked but aren’t really track cars. They are fantastic all-arounders. BMW, in trying to keep with the performance mantra of its M products, reduced weight in a location that benefits performance. And in doing so, made the effort very visible and unique to the M products. Yes, M now has the dual meaning of Motorsport and Marketing, but I do appreciate BMW offering features and options which both support the concept of an M car and are not available on the regular series cars.

The cf roof is for torsional rigidity. Weight saving is secondary. Losing the muffin top, on the other hand, should be the primary concern for many.

This is very true. The carbon roof separates single-digit M's from three-digit ones. But the question is whether its use is justified on a passenger car or is it more like a show-off accessory? As others stated, 45lbs of weight saving on the roof doesn't add much performance benefits. I found an older topic from 2019 on the same matter for F82. People couldn't agree either. I'm not surprised that nobody agrees 5 years later.

Who’s to say having the sunroof will hurt resale?

It’s obvious by this thread that we have what looks like a 60/40 desirability.

When these cars trickle down to a different bracket of affordability the sun roof cars will be much more rare.

And there’s obviously demand.. and low supply.

5 pages may not be enough. I want the sunroof. I just wanted to see whether people who don't race choose CF and why they do so. Maybe I am missing something. So far, I'm missing exclusivity, a free $3500 option, weight saving, torsional rigidity, potentially not having to fix leaks after 10 years. So far, I'm not convinced that having a CF roof is worth losing the ability to see the sky and get air and sunlight on a nice day and not getting a same-color roof.

I didn’t want the CF roof for resale but no way a sunroof car will have the same desirability (all else being equal) as a CF roof car. Same with convertibles. See previous generations of M3s…

Honestly, I got the CF roof because I think it looks really cool. 😎 Never going to track my own M3, just love the look.

OP, sounds like you’ll be happiest with a sunroof. Either way I’m sure you’ll love the car.

Thanks for the honest opinion! It does look cool, I must admit that.

The same ratio of people who buy new with CF and new a sunroof will be buying used with CF and used with a sunroof. Right now there are 196 used G82's on CarGurus. Only 31 have a sunroof. Only 11 with 6MT. That's low supply for 4 years of production.

This thread is pointless. Someone got sunroof and now trying to prove the internet that’s the right thing at to go.
Come on…. Nobody cares. I got what I got cuz I like it.

Good chunck of these threads are pointless, but as car guys we all like to give or 2c on car matters.

I don’t think it’s the same ratio when the car is a couple of generations old. When enthusiast cars age, the ‘enthusiast spec’ tends to become more desirable.

I am not saying that alone will make the difference, i said every bit counts. So yes, lighter wheels, removing rear seats, passenger seat, lighter driver seat - all those will help every little bit. if you can shave off 40lbs (of the sunroof), that's even better.
