Dino,
Slowing things down... just to slow them down is not always the answer. We can go round and round on this, but my main intrest in the GT type of racing has to do with the scale,fun kind of racing, and bringing new people into the hobby with a class that they can relate to .
Yes slowing things down usually is a GOOD thing, but at he same time, it needs to be fast enough for people to go "Wow... That seems fun.. and those things sure are quick....". I can assure you that people do not walk into a hobby shop and ask for the slowest car on the shelf.
Also, about the tire, as has been said a few times.... We are going to test it. If it works then we have another option and can save the racers a bunch of cash... If it does not... then.. I guess you know the answer.
We are moving forward with our plans for GT racing, I hope you guys can come check it out. I am kind of bummed you guys do not subscibe to what we are trying to do, as we do not have any cars that fit your rules anymore.
