The reason why the speed limiter is enforced more on all vehicles sold in the US whether they are made here or imported is because we have higher safety standards than some other countries when it comes to automobiles. For instance we require shatter resistant glass on all vehicles sold where as many other countries like Japan for example does not. You can get it as an option but it is not required. We also require every motor vehicle sold to be equipped with seat belts but some other countries like Korea do not. And the speed limiter is not 155MPH for all vehicles as you say, do your homework and you will see. The Ford GT is a perfect example as it is made and sold right here in the good ol U.S. of A. and it is limited at 220MPH, not 155MPH. And the reason why is simple, because it can safely go that fast.
Now that I have cleared that up let me retype what I said previously in a format that will be a bit easier for your brain to digest. I did not say that it isn't capable of going faster than the limited 155MPH. What I did say is that it is not capable of doing it safely and that is why they limited it to 155MPH.
Now, you do your research and then post. Thanks

An FD can go 180 SAFELY on the freeways with coilovers and swaybars on stock tires and rims. The government imposes speed limiters to reduce deaths on the roads. Its safety against those who cant drive, not the car itself.

I've run sustained speeds of 140+ for a good half hour and it felt very stable. Hit a peak of 156 and felt it could easily do more. I think most cars nowadays are limited because of the gearing(overdrive) and power being put out in this new muslecar era.
Here the video too, it was during the hurricane rita fiasco...

You aren't going to any "event" where you are going to be doing over 155. You don't have the safety equipment in your car to run those speeds in ORR texas mile or drag racing, you also have nowhere near enough power to break 150 on any track in the lower 48. You don't need to remove the limiter. Stop.

Can't wait to see what i'll get on the banking at Cal Speedway in a couple weeks. I'm hoping for over 140.

First of all, NO! This speed limiter of 155 is placed on vehicles that are brought into the US! The same vehicles in other countries use the same exact tires and have the same coefficient drag properties yet they dont have speed limiters. The government places these limiters to limit car crashes and deaths per year. Only an idiot will do high speeds on a pothole. The speed rating on a tire is totally different, some vehicles are equipped with Z rated tires and they still cannot exceed 155. The BMW m3 is capable of much higher speeds than 155mph, and also the BMW m5, and the supra twin turbo. Yet all these vehicles had the 155 mph speed limiter. You're telling me these cars cant do 155+ safely? Go back and do some research, then post. Thanks

Don't understand, here is discussion how to cut speed limit, or why we shouldn't do it??
I have JDM Firelady Z, and I have 192kmh speed limit, it is terrible, I can't even test car on dyno, because 1:1 ration is on 5th gear
So is any way to cut speed limit?? I have good offer of emanage ultimate, but not sure if this ecu can do it.
any idea??
