How's the fit? Any problems?

The only one I've ever seen actually fit rather nicely. The only thing I didn't like about it was that it wasn't painted to match the car. Member John Coffey sells them at his shop. You could PM him and he could likely tell you a lot about them.

Thanks Stephan! I will...

One guy on the HybridZ forum has them (RB Z or something like that. Its red). Seems to fit very well. The betamotorsport one looks very well done.

There are also a few other ones from Japan.
