I thought it looked more than a little like my buggy... Definately get the ackerman then... and upgrade to the aluminum steering servo saver too as it's the weakest part. I broke a couple before getting the alumiunm one. They aren't cheap - $50 - but its worth it. The King Headz center dif brace is also fairly important. Those are the only upgrades I have on my buggy, and its just plain awesome. I couldn't tell if the radio/servo tray was carbon fiber on your ST. The S3 came with a carbon fiber tray, so that is available if yours didn't. Damn, now I want one of those more than ever... I LOVE my S3, you are going to feel the same about that ST I am sure!
