I think by now most people would have heard of Motul in the car communities but I will chip in here on Motul: I switched from the purple Liqui Moly GT1 to the Le Mans 300V Motul on my Subaru. It was not a cheap switch and I can't vouch for the lower-end Motul products, but in the couple of years I used it I swore by it! It made sense since the car was used the way it was and the platform was a disaster that needed the best band-aids possible. I was considering a swap to Motul on the M5 as well. I use the brake fluid as well (RBF660).
We can do the RBF 660 on the car otherwise they have a new version out called the RBF 700.
higher boiling point then the 660.
I just mentioned the 5.1 as a lot of the guys wont be using the car to the point where they would benefit from the RBF660 or 700.
However that being said... i can definitely do the RBF fluids
