If there's one class of racing sure to spring a few unique machines it's Super GT/JGTC, especially in the GT300 class. And this car is one such case; a Porsche 968 GT300 machine.
Known as the Arktech Endless Advan GT4, this one got me interested, as whilst there have been plenty of Porsche's racing in the GT300 class, they've mostly been 911's, so to see that a 968 had been used, was quite interesting to say the least.
From what I can gather, it seems it only competed in one season; 2004, and seemed to be quite competitive, or at least at a the same level of it's 911 brethren. Spec wise, it used a heavily tweaked version of the standard 3.0 Litre 4-cylinder Turbo unit, with 380bhp, but had the potential to exceed 500bhp. Which considering how light GT300 machines were, and still are; roughly 1165kg in this case, means there's no doubting it could shift. However, despite this, it wasn't as rapid in a straight line as perhaps expected, at least not as fast as the leading 911's in GT300 at the time. Reportedly is was as much as "30kmh" or so slower than the leading 911's.
Read quite an interesting article on this site, which detailed some intriguing info about the whole thing. Sadly however, the company responsible for creating the Advan GT4 968; Arktech Motorsports Inc. seemed to have vanished since. However with that said, guy in the article emailed Rennlist; a big Porsche enthusiast site/company, where managed to email an Arktech Motorsports spokesman;
Hiroya Iijima. He gave quite an in-depth, "inside" amount of, mentioning how the Arktech 968 managed to qualify 2nd at SUGO. Though not sure whether he meant second in GT300, or 2nd amongst the other Porsche machines, as "best of the rest", due to the way he worded it. He also mentioned how the 968 was capable of over 500ps/hp without it's ristrictor, but 30km/h slower than the fastest Porsche, as I mentioned above.
What's even more intriguing, is that a guy in the article emailed another Arktech spokesperson about the kit used on the GT300 machine. Basically it seems that was initial plans to sell FRP copies of the wide-body kit used on the actual racer, but it never really happened, due to it being hard to fabricate, difficult to install, especially on a standard 968, and presumably costly.
However, the email then goes on to say how one customer has actually specially bought a copy of the kit for themselves in the U.S., for their own creation. Plus it would seem they are (or at least were) still open to special offers of one-off orders of the kit. All in all, it's a really neat to think they there was plans to create somewhat mass-produced copies of the Arktech kit, for customers to use for themselves on their own 968's; similar to whole RWB setup with 911's, as the article points out
.
Either way, details of the car's whereabouts after 2004, are scarce from what I could see, so I'm not 100% whether it's still in action today. However, it did get me thinking, as it'd have been a perfect candidate as a hill-climb machine, like so many retired race cars are often converted too. Even more so with something like a GT300 machine I'd have thought, with the low-weight, and good power and aero...
