Chris... I got 2 prototypes for the BMI asphalt chassis this week. It's 2.25mm graphite upper and lower deck. Jason probably won't make towers for this kit yet as the stock towers are 3mm anyway. We have some other cool stuff in the works anyway.
The 2.25mm graphite is still stiffer than the stock chassis, but it seems like it's going to be the perfect amount of flex for asphalt. The top decks that I have are the same as the carpet ones, only made out of the 2.25 graphite. That way you have the adjustability of the corner posts. We'll see how that goes.
And Robbie, I have NO clue what you are talking about.
