My understanding of the 155 limiter is that it stops the German makes from having a top speed war. Also I guess the stock tires just are not up to it.

I see nothing wrong with bringing a high end car up to its top speed, thats what you buy them for. What is the point of buying an AMG anything and riding around a 55mph on the highway?
