Rumours :

1. unofficial rule in Japan to limit cars power to 280PS (276bhp) Although there are blatenly cars producing more power than this.

2. unofficial agreement to limit european (well certainly in Germany) cars to 250kmh (155mph) Except Porsche didn't agree.

3. Gatso speed cameras wont catch a car doing 156mph or faster.

 

Hmm, hey guy, i've taken the 6mt to 159 way too many times. There's no 155 limiter.
