just get a piece of yellow tape

Inspiring.

I just put a green piece of tape on the top my wheel, and it's more helpful than I thought in keeping it straight. Thanks.

Hahaha, I guess I'm lucky. My current wheel is Microsoft's Wireless FFB racing wheel and the worst I've ever done to it is whip it around (drifting!) so hard that it made a crack and now rotates slightly more on the left side. It's nothing horrible, though, the wheel is in perfect condition otherwise.
