I find it hard to agree that this is an issue in practice. The E60 M5 has such little body roll for a car of its size, so I cannot see where any complaint would come from that there is 20kg sitting above the roll center. If there is an aesthetic issue, I can understand the complaint, but dynamically I do not see the issue.tend to agree with the OP and the subsequent posts. Putting 20kg above your head lifting the COG, even in a GT, seems ridiculous to me. Never ever use it and would rather it wasn't there. But the cost to delete it, not a chance.
ECS Tuning can get you any part that is on a BMW. But it's probably not going to be cheap.41317111362 roof panel

if anyone has links to anyone who has done this please please let me know where I can find them.
as far as motivation, I despise sunroofs.
heavy, ugly, leaky. this car is a pig Id like to shave off a few lbs where I can w/o sacrificing the cars true luxurious nature.
wrap is a gimmick. I want that slicktop Alcantara headliner when I look up :devilThough it wont net you your 30 lb weight savings, if you wrap your roof it'l get you the aesthetic of a slick top with out the astronomical price. Also could be undone if you want later for whatever reason.
Between the labor involved, sourcing parts or getting custom ones fabbed up, this is one of the rare times I'd say it's cheaper to add power with these cars.
If you're serious about shaving weight, I'd go for any rotational mass first i.e. wheels and drive shaft before chopping up the body structure. That will at least get you some meaningful pounds off of the car.
hmm, I wonder if that's why they put a carbon roof on the new even fatter f90 M5......Not much of a market for a cf roof for a fat 4 door with every bell and whistle available when new except for cf. Kinda like ordering a whole pizza for yourself but having a diet coke because you're watching your weight imho.
Here ya go chiefehh, no they can't.
