Does the series have a future with no RHD GM cars and the next mustang platform only being LHD?
Kind of a minor issue in my view as the cars have nothing much to do with the road cars you can buy here anyway. Wheelbases are different, you haven't been able to buy a Ford with pushrods for nearly 30 years, there was no V8 option for the latest gen Opal, sorry Commodore, ditto the Nissans, both the latter are front wheel drive.
I was going to add that at least the Mustangs are dealer sold here and any road going Camaros will be converted private imports so you won't see many of them on the road but then I could say the same about the last Opal/Commodore. I think they sold about three of them. So I don't think the fact that Camaros aren't produced in RHD is the issue, its that you won't see them on the roads and in the showrooms.
I don't know how they solve this. I think the organisers have done a great job for 3 decades managing parity between the Holdens and Fords at least which has made for great racing. No reason why they can't continue to do this with Camaros and Mustangs but it you don't see them on the road there will be a lot less interest. I know that I was less interested during the Fox Mustang and Sierra era, even though I'm happy anytime anything with a Ford badge wins. I certainly wish Dick well, he is a survivor and a true blue Ford hero who has stuck with the brand through thick and a lot of thin.
In my main motor sport interest, drag racing, similar issues have been at play for a long time as far as sedan based classes are concerned. Both in the US and here the more or less equivalent of the Supercars is the Pro Stock class. In the US these are 500 cube, two valve per cylinder machines that only recently moved from carbs to EFI (and slowed down as a result) that run in the 6.50's. Here they are 400 cube two valve engines, still on carbs that have run a best of 6,87. In both cases they use "spec" bodies that look not much like the road cars (and you can't buy the road car here anyway). Interest and entry numbers are dwindling. Covid is likely to kill the class in the US.
On the other hand, interest, enthusiasm and participation for what they call in the US ïmport" racing is booming. Hi tech, multi turbo, EFI, multi overhead cam, highly computerised mostly Japanese based machines that have run as quick as 5.70 in the quarter. While they also use the spec bodies, this is gear younger generations of fans can relate to, unlike the Pro Stock dinosaurs, as much as I love them.
The other class that is booming in the states is a relatively new Factory Stock class where basically showroom Mustangs, Camaros, Dodges feature, i.e. cars that the public can relate to. Kind of like the old Series Production class from way back when - get it from the showroom, drive it to Sydney and back to run it in, pull the engine and blueprint it and go racing.
It reminds me of when I was installing the new engine in my '66 and my young Asian neighbour, who had a pretty hot rotary Mazda, asked me what I was going to use for engine management. He couldn't understand at all the concepts of a carby, mechanical and vac timing management etc.
Sorry, this ended up a much longer post than I intended. Anyway, we all love our old Mustangs, but I reckon progress is going to catch up with the Supercars in the not too distant future.
