My gut feeling initially is I didn't like being grouped in with G5 cars. The Swift is not exactly a very powerful car, and going up against Martin, Lance and yourself Pat didn't feel very fair to me.
However, I haven't complained officially about it because I feel I don't have a leg to stand on. I'm still at least 5 - 6% slower than Peter K was in the Swift at GCFR in the same, if not better car (i.e. dog box). And Peter K used to trade times with Martin Walter, sans restrictor.
My feeling is if former G5 cars are allowed to run next year without restrictor and it is re-evaluated at the end of 2013, I'd support that. HOWEVER, if the former G5 cars start running away with it I'd request to have the restrictor added back in. Either that or I'd get a G5 car instead

The other feeling I have is that it's too cheap for a G5 car to make optimal horsepower whereas achieving that same HP in a G2 car is far more expensive. Maybe with some G2 cars this will be easier with the newer higher displacement limits, but for most cars it won't be feasible anyways. I doubt anyone can find a 3L NA engine to cram into a Golf or Focus without spending $$$.
I think for the
top end G2 cars vs G5 cars, the performance will be so similar it won't matter. Where it will matter more is for the less powerful G2 cars. What I do know is that for next year, I've accepted I'll probably now be close to last in 2WD in every single event unless I can pull some courage out of my ass and stop worrying about crashing, which isn't likely to happen.
