I had AVSi's on my 300ZX and they wore for shyt. Lasted less than 8000 miles after a set of Dunlops lasted me 25k WITH autocrossing them! I swore I wouldn't go back to the AVSi's but it's starting to look like after only 8500 miles I may need to replace the rears on the S2000. If the AVSi are that cheap it may not be bad because they DID stick like crazy and handled pretty well. They were noisy as hell though.
