contact LewisHi Toyo, Lewis here. That's a good question. I would suspect the fastest Subaru STI for sale is going to be one that has had the electronic speed limiting removed. For example, the 2011 Subaru WRX STI has a speedometer that goes to 160 mph. According to Subaru, the top speed is around 158 mph (per Car and Driver). Supposedly that speed is drag limited, so that means if you can get more power out of the engine with performance mods, it may be able to go a bit faster.

Most vehicles these days are electronically speed limited though; some people get around that restriction by using larger tires. A larger tire makes less revolutions to go a given speed, so it makes the speedometer read lower than it would normally. So if the speed is electronically limited through the engine control unit, that's one way around it. Also if the top speed is gear limited (meaning the engine is at the redline at top speed), larger tires can be a way past it too without having to modify the transmission.
