00_HO_Contour,
I used to run Yokos AVS's on my Supra when I autocrossed it, and they performed extremely well. I was very happy with them. So much so, I bought them for my SVT after I got rid of the Supra. I ran both the Supra and SVT in SM classes.
I also run my SVT with AVS's primarily for Autocrossing. My SVT mostly stays garaged and is not my daily driver.
I must say I have been dissappointed with the Yokos and the tires on the front wore exceptionally fast. I had to rotate quite frequently. The last race I was in I literally trashed them. It looks like I have slicks on now. Once the tread gets very low, the tires lose a lot of grip (unlike a lot of other high performance dry tires). Last race I was in, the car exhibited a lot of oversteer (more than normal) above 25 MPH, and as a result I performed terrible, even spinning the car out. I guess the AVS does not run as well on front-wheel drive cars.
Next tire is going to be the Azenis RT-615 for sure. From what I have gathered, a great thing about this tire is it's temperature and wear properties. If you autocross or drive hard, get a pyromometer and compare the results of your current tire to the Azenis. You'll see what I mean.. they cool down quick and perform consistently under a broad range of temps. Also, Azenis have been known for performing better the more they wear. They are very popular with Neons, Miatas, Acuras, and WRXs. Almost no one runs Yokos for autocrossing.
Anyways, I would not recommend the Yoko's for our cars. I hope my two cents helps some, and I'm sure someone will disagree... such is life
