I’ve had the worst experience trying to source a set. I’ve reached out to Brabus through calls texts email and nothing. I finally got a hold of a performance shop who is Brabus authorized. Talked to him once he was supposed to get back to me and never did. Anyone know or have someone that will actually sell me them? Crazy I can’t get someone to take my money. lol.

I had my local tech who does all my cars reach out to Brabus and he sourced it and it came in a few days after he contacted them.

Try talking to Ben at RG Sport in Irwindale, CA- he has worked on 10 of my M's, the GT63, RS6, 992, R8, C8Z06, Tesla Plaid (yep), etc

Now he doesnt carry GT63 stuff but I knew he would get what I wanted and he is a great wrench too.

Here is his shop

Hey thanks for the recommendation. They have been far the best. Very responsive and keeping me in the loop. Apparently they are hard to come by from Brabus and Brabus itself seems to be slow at response to them. I may get them sometime this YEAR. Lol.
