JDM cars like the Evo, STi and Skyline are speed limited to 200km/h. This is due to a gentlemen's agreement among the Jap manufacturers in the name of civic consciousness/ public safety.
The remedy is to install a de-limiting device such as the Aprexi Rev Speed Meter or the Pivot Speed Meter (approx. RM200).
Not sure whether this applies to Japanese-spec BMWs.
That one only applicable to the stock cars. But if you go to "Shibuya", "shinjuku" and "Roponggi" turf, normally they already by pass the speed limit and equipped with the camera detector to avoid the speed trap. Nowadays the JAP "kokosei" also knows how to do it since the implementation of US DIY program. :burnout:
