I have purchased many carbon pieces from Madness and very happy. Great fit, great service from them and I prefer the carbon look over the factory Aluminum.
It is genuine carbon and not some plastic copy so it all have great weave pattern and consistent and very nice finish
The steering wheel piece just slides under the airbag. You do not have to pry or remove anything. I put some very thin double side tape on the tips and let it warm up in the sun for a bit and it goes in very easy.
The pieces fit very good so install is very simple.
Have to get some very thin double side tape as to not create a gap
I got mine off a combo of ebay and ali. and really wish i could have gone the Madness route. Fitment on especially the center panel was so-so..if the madness stuff did not fit i'm sure they would work with you. One of the pieces i got would not bond on (shaping was off and/orr the double tape was not 3m) and they (ali vendor) would not work with me at all). For the high profile pieces go real carbon people. I have a few tiny pieces of abs-carbon-look and its sooo fake. I'm used to real carbon in other sports/interest and i can spot the fake a mile away.
BTW i was not going to go the carbon left and right vent covers but man, there's a Ferrari FF on BAT right now with that treatment and looks sooo bad ass
