First of all, you need to specify which g-Force tire you're talking about. BFGoodrich uses the g-Force name on a lot of their tires (just like Bridgestone does with Potenza, Kumho does with Ecsta, etc). I realize from the link that you're referring to the g-Force T/A KDW2, but it's still worth keeping in mind, so you don't confuse them with other tires carrying the g-Force name. In fact, Falken used to use the Azenis name on another tire (the ST-115) but that tire has been discontinued, and AFAIK it now applies only to the supersticky RT-615.

The Falken Azenis RT-615 is designed to be a supersticky tire on dry pavement, so that it can be used on the track as well as on the street. It offers great grip in dry conditions; downsides include rapid treadwear (10-12K miles in street use is typical) and so-so performance in rain.

BFGoodrich makes a similar tire, but it's the g-Force T/A KD, not the KDW2. Compared with the Azenis, the KD doesn't grip quite as well on dry pavement, and it's a whole lot more expensive.

The KDW2 is a summer tire designed primarily for daily driving, not track use. Not that you couldn't use it on the track, but it won't perform anywhere near as well as the KD, let alone the Azenis. The KDW2 is similar in performance to the Kumho SPT, a daily driving tire with pretty good dry traction, excellent traction in rain, and fairly long treadlife. However, it costs almost twice as much as the SPT, so if that's what you're looking for in a tire, you're better off with the SPT. As another alternative, in the same price range as the KDW2, you can get the Goodyear F1 GS-D3, which gives better dry performance, better wet performance, and longer treadlife than the KDW2.

So, bottom line, here's what I recommend.

If you care ONLY about dry traction, and not about treadlife or wet traction, get the Falken Azenis RT-615. If you plan to use these tires on the track or while autocrossing, you are probably in this category.

If you care about dry traction, and you also care about treadlife and/or wet traction, get the Goodyear F1 GS-D3.

If you care about dry traction, and you also care about treadlife and/or wet traction, but you're willing to trade off a bit of performance for a lower purchase price, get the Kumho SPT.

 

the on linked on the page sorry, but thanks

 

Azenis

 

the kdw2 can be used on the track whether it is auto x, drift or drag racing. As well as the azenis RT615. question is which is more practical. the azenis sport is definately more practical price wise. i have seen both tires used in both ways. i have personally driven on both tires and the kd on an auto x course as well as a drift course. the kd in my opinion was more stickier and was more responsive to me than the kdw2. the azenis rt615 was predictable as well as the kdw2 on how the 350z did handle on the course. between the two tires thou i did favor the rt 615 because responsiveness wise it would let you know when you were about to exceed the limits of the tire before the car spun around on you...
