Got some experience with this whole GT racing thing too,.
Unless an event or a track is organized to be “brand” specific, there is no way to keep other manufacturers out of the “GT” arena anymore. Those days are pretty much over. I know, being the guy that started the “IGT Spec Class” program in Tampa and helped craft the rules that some groups around the world are using today.
There are also the racers that want to run the GT cars in an “Open” type class. While they are few in comparison to the “Spec Class” guys, like me, they do exist and should find a way to grow in popularity without forcing the “Spec” cars to race with them.
I’ve been accused many times of being a “hater” to the “GT Open” class, but it really is far from the truth. I do understand where they’re coming from, however I do prefer the spirit of the “Spec” class concept.
On the subject of engines, I totally believe that the “Spec” cars should be allowed to use any of the RTR pull start engines available in the RTR cars, regardless of manufacturer as well as, a suitable equivalent with a retail price in the same range as the RTR engines that come in the “GT” cars from the factory; That also includes exhaust systems.
There should be some kind of “Claimer Rule” to prevent excessive modifications to these engines out of fear that the racer would lose it after the race day is over.
On the subject of electronics, many racers have spare electronics around after years of racing. The RTR electronics are getting better, but they are still not up to par with what is needed for serious racing efforts. The durability of steel gears and the torque needed to steer & slow down these heavier chassis just isn’t there in the RTR servos available.
The advent of DSM radios also eliminates frequency conflicts that exist with crystals.
On the subject of tires, rubber tires really are the way to go with the “Spec classes”, while “Open Class” cars should be allowed to run foams if they wish or its determined that the higher powered cars need them. Tire choice should remain up to each racer; there are “kit” and several good “pre-mounted” tires available that far surpass the RTR tires which will only destroy cars due to lack of traction in racing environments.
On the issue of bodies, there are many fine examples to choose from, ProtoForm’s new PF8GT is very nice and I’m sure there will be more in the future. The only bodies that should be excluded are the Lola type bodies because they would eliminate all the bodies that actually look like real cars; which is one of the single largest attractions of this class.
If a manufacturer wants to start their own series they can call the shots and that’s very cool too.
Otherwise the best we can do is try to maintain a somewhat level playing field between the manufacturers of GT cars and supporting products that are available now & the ones yet to come.
I think the people at Roar are trying to do exactly that. They seem to be keeping a low profile while they figure it all out in fairness to all.
