I have a GT-4 RTR...with the stock gearing it does in the 50mph range, but with just a gear change I'm pretty sure you can get it to 60mph. I don't have a radar gun, but when I drive it, it's faster than I can control. Oh, and if you're thinking of that car or a Nitro 4-Tec (many people do), get the GT-4, you'll be much happier in the long run.
