I've had these for a few days now to replace my old economy tyres that came with my new wheels as I do a lot of spirited driving around the extremely twisty mountain roads in Victoria. First impressions are that my car has so much more grip it is unbelievable, especially being they are suited for hot weather and Australia has plenty of that. I observed that the car is extremely confidence expiring around turns, which I can take at 15kmh per hour more or even more, keep in mind these turns are not wide high speed sweepers but rather extremely sharp lower speed corners and the amount of turn in I get with these at the front is unbelievable. Paired with my stiff suspension and sway bar set up, the car rotates extremely well into a car, and maintains grip in the middle of the turn with no worry. Being that my car is FF, I get a bit of wheel spin if I floor it out of a corner, but now the tyres just hook but also causes a bit of torque steer which is of no fault of the tyres, but a FF car. I can't even get my wheels to spin if I launch at 4k rpm, despite having a k24 with much greater low end power.
Braking is mind-blowing, even at half throttle braking, the car will break so hard you're head will go flying forward, and with full braking, the car will break so hard and come to a full stop from 100 in a blink of an eye, so fast that it is very easy for the rear to get extremely light to the point where it gets squirrelly in the rear even with a almost perfect straight line stop. Honestly braking in the dry is a 10/10 for me and so is the handling. The feedback is unbelievable and personally I am not too fussy about comfort as I daily this car and it has very stiff suspension for a daily street car.
I have not yet to test them in the wet nor do I have enough mileage in them to give a review. But in my short time using these they are unbelievable and a major step up from my old tyre and also re003's which I had in the past and also pilot sport 4's which were much comfier but performed worse in braking and handling, but especially the feedback. These are also much cheaper. So far I am in love, but am concerned with wear reading the other reviews, especially since I take it to the mountains usually 2-3 times a week but worse wear comes with the territory in these categories of tyres.
I plan on replacing these with Goodyear F1 A5's after these wear out to give a comparison.
