You may want to check the speed rating on your tires first.

Aside from all this f&f ramble, most JDM cars indeed only have speedos that limit to 180km/h per:
Quote:
However, the speed limit of 180 or 190 km/h remains in effect, depending on the make and model of vehicle. Many JDM sports cars have speedometers that only go up to 180 km/h, even though the car would be capable of much higher speeds if not for the built-in limiter. Some cars, such as the Nissan GT-R, detect via GPS whether the car is on a Japanese race track. If so, the speed limiter is disabled.[3]
from: Japanese domestic market - Wikipedia, the free encyclopedia

Since this dude is from Thailand, cut him a break his car probably can only really go to 180km/h. He has a legit question
