I activated mine. It is in the Z4 part of Bimmer. Thic Whips on You Tube has a great video on how to activate. It only allows you to change the engine and transmission. I could notice a quicker shift and a more responsive pedal. Not much else. It is easy to do and worth it. If you are paying...
I got Maxton V2 Lip, skirts, and spats. Look pretty good. I decided to go another direction with the skirts, but keeping the lip and spats. Maxton is pretty reasonable, not crazy money. CF is getting overdone so trying to stay away from more of it.
I am selling my Maxton V2 Gloss black side skirts. Looking for $150 includes shipping. They were only 3M taped on, no holes. I have the hardware as well. Hit me up.
You can ask the dealer to put in a different oil viscosity with Toyota Care. I had them put in 5W-30 for my first change. 0W-20 is like water in the southern heat.
They cannot do crap if you have an out of state license and registration. If they give you a ticket you can give them the finger if out of state. They can't do shit.
