A lot of people are cranking up the power in their street Camaros to the 450-550 range so I think it's perfectly valid and sensible to match your development car to what so many of your potential customers have. Racing has always been the test bed development arena for the high performance features that have trickled down to the street level.
Pedder's "gets it" and is doing it right and the results show. Power is useless if you can't control it and Pedder's is demonstrating to the "power" customer that their packages gives them the kind of control that gets the job done. Using Paul Tracy to demonstrate that shows it's pro-quality stuff not something that a pro would never buy.
Of course there's "PR" to it; that's what sponsor stickers all over a car, the track, the walls etc. are all about. I've got a Pedder's package ordered, just waiting for the parts to get in so I can get it installed on my car. Great job Pete and all who participated!
