mugenb46- Unfortunately these forums are notorious for spreading rumors and getting top level drivers in trouble so you probably won't see the info you're looking for posted on this thread. The best thing to do is ask this question to the driver's directly. You can pm many of them on here and might even get a few to speak to you over the phone. I'm not sure what info you're looking for but I can tell you that not everything posted above is entirely accurate; some of it could even be described as complete shots in the dark.
*Disclaimer* This is not to discredit any one of the claims on this thread in particular. I'm sure some of you know a pro or two personally. In my experience in the industry much of the responses to this thread are off the mark just a bit and I want mugenb46 to get the best info possible.
