It's funny how much people on this site bash Integy while talking up RC4WD. A lot of RC4WD's products are on the same quality level as Integy. RC4WD makes nice wheels and tires, but even those aren't without problems. You have the RC4WD Raceline wheels cutting the bead clean off of tires. I've had a set of RC4WD beadlock wheels on which the beadlock ring bent under the "pressure" of an RC4WD tire. And then you have the TF2 and D90 kits that have all types of issues. Massive tolerances on the parts that lead to sloppy connections, soft metal that makes these sloppy connections worse over a short period of time, machining issues (untapped holes, incorrectly placed holes, etc.), and parts missing from the kits. On top of all this, you have RC4WD's horrible customer service. Integy has zero customer service in my experience, but RC4WD isn't much better.
So just be aware that Integy is not the devil and RC4WD isn't the almighty.
