Discount Tire for a set of 4 would run me about $700.00:frown:
Vulcan Tire would be $670.00, including shipping.
That's for a 215/40/17 & 275/35/18
I suspect the $500 figure mentioned above is for 205/50-15 and 225/50-16, for 15"/16" wheels. Still, $670-700 for these 17"/18" tires is a relative bargain. (If you want lower tire prices, get smaller wheels. :smile: )
BTW, if I were using 17"/18" wheels, I would get 265/35-18 in the rear, rather than 275/35. Better fit, better handling, better acceleration, etc.

I'd still go for the RT615's. They are fantastic! They are quiet riding tires that are just perfect for street/track use if you are looking for one tire to ride on all the time. Love 'em! I have GSD3's on my other car and those are amazing street tires, but they aren't track tires.
That's the first time I've heard them called "quiet riding tires". They have great dry traction, but they're relatively noisy.

The Azenis are fantastic tires ( I run them) but they really suck in anything except dry conditions.

It's basically a hard R-compound with tread depth.
And not all that much tread depth! Most summer tires come from the factory with 10-12/32" of tread depth (all-seasons and winter tires sometimes even more than that), whereas the RT-615 only comes with 8/32". That, along with the soft compound, is what makes their treadlife rather quick.

They're a great tire if you're lazy and want to drive to the track but it's no substitute for a true med-soft R-comp. It's the absolute minimum I would use for the track but overkill for the street.
The RT-615 is still a street tire, for sure. I wouldn't consider it "overkill" for the street - more along the lines of "if you're looking for dry traction on the street, to the exclusion of anything else, this may be a good choice". I also think that beginners on the track are better off with their everyday street tires, while experienced folks probably want R comps anyway. But different strokes (and if you need one tire to do both)...

The GS-D3 are a great, cheap tire and you don't have to worry about rain. Unless you plan on more than a couple autox sessions or more than 1 track event per year the GS-D3s are the smart choice--unless of course one only drives in dry weather.
I think the F1 GS-D3 is a great tire. "Cheap" is relative - the purchase price of the GS-D3 is less than the top-of-the-line summer tires from some other brands (Bridgestone, BFG, Yokohama, Michelin), but more than others (Kumho, Toyo), as well as lesser tires in their manufacturers' line. I'm not knocking the F1 GS-D3; in fact, I think it's a great all-around tire, as good as the more expensive tires and better than the cheaper ones. Also, I think it's an excellent choice even for those who only (or mostly) drive in dry weather, but who prefer a tire that lasts longer than the RT-615. The F1 GS-D3 is more economical than the RT-615 on a cost-per-mile basis; even though the purchase price is higher, the better treadlife more than makes up for it.
Both tires are excellent tires; it all depends on where you want to make the trade-off, better dry traction vs better wet traction and treadlife/value.
