And that's the heart of the matter. Time attack is a "form of racing", and, as such, cars purpose built for time attacks are "race cars" by definition. Well, if "time attack cars" are "race cars", then there really is no argument to be had, or? The HKS CT230R is a "race car" by definition.
There it is again. A "form of race cars. And that's the whole argument, isn't it? If something is purpose built for a "form of race", it is a "race car". That's what makes a rally car a race car, right?
Or did I misunderstand anything here?
You have changed your stance & my argument. This is what you originally said,
Though I, personally, don't see how it could possibly be a race car, as race cars are purpose built for races, and the HKS CT230R, quite clearly, wasn't. It was purpose built for time attacks, which is something that traditionally was born out of the tuner community, not the racer community
You said the HKS CT230R can not be a race car because it was purpose built for Time Attacks, which insinuates that Time Attack events are not a form racing b/c the cars within it are not race cars.
My argument was not to define the car as a race car. It was to point out that Time Attack events are indeed a form of racing just as the WRC is, as again, a race does not have to between 2 cars at an exact moment.
The cars within' are
not necessarily racing cars because (you, yourself said WRC cars are rally cars, not race cars) TA usually have multiple classes defining eligibility. I do not consider the man who occasionally tracks his Miata w/ a roll cage & some sticky tires, and then spends the rest of his time driving it around town on road-spec tires as a race car, which is what a lot of TA cars are quite close to, i.e. the tuners.
The cars within Time Attack series' that are the race cars are the ones dominating the series. Somewhere along the road of tuners, someone realized that if they wanted to beat the competition, they were going to have to resort to high downforce wings, extreme weight saving strategies, & sleek, wide bodies for aerodynamic gains.
The result ended up in teams building purpose-built race cars b/c they realized that was the only way to go even faster. As time as progressed, these cars have gotten further & further away from a tuner & a lot closer to the cars you see in the SuperGT. In fact, here's the CT230R racing the Weds Sport IS350 during an event.
The SuperGT cars are amongst the fastest race cars in the world & for a "tuner" to keep up with one, it'd have to become a race car itself.
Edit* Regarding the building process of some of the TA cars like the HKS, they are somewhat a mix of SuperGT & FIA GT regulations.
