No, they do not. For quite a number of years, the German manufacturers had a "gentlemens agreement" to limit off of their models to 155, to head off imminent legislation to that effect after a series fo horrifying autobahn accidents. But they started bypassing that for the serious iron years back.
SRTs policy is that they have no limiters except simple drag/power. As fast as the engine will psuh the car through the air, thats the limit
Most cars, like R/Ts, etc, they do have one, set to a couple mph below the speed rating of the stock tires. Normal R/Ts were 130, but Daytonas and Road and Track packages, that came with tires rated to 150, got the limiter set to 148 or so. SRTs have tires rated to about 180 or so, but gearing stops them at about 173-175.
The Neon SRT was out of the box capable of about 145 or so, but adding the Mopar Stage kit raised that to the 170 range, and so new tires of that capability were recommended.
Even at 130 mph along the back straight—top speed is 175, says Chrysler—the 300 SRT8 remained firmly planted, and there was virtually no wind noise.
