These are Dunlop D01J competition tires. They are very similar to the Yokohama A032R's in that they are a hard compound semi-racing tire (meaning that they will last for 10-15k miles and stick better than any other street tire out there). They are not available in the US, so we are importing them from Australia. For available sizes, see... [ www.stuckey.com.au/street.htm ] Price for 265/35/18 tires are ~$309 + shipping (depending on the exchange rate). Shipping will probably be around $50-70 per tire... less if more people join (price for the tires may go down as well). They are perfect of for those of you who want to extract every ounce of performance from your Z on the street... they provide excellent straight line performance, but at the same time give great cornering ability because of the stiff sidewall. They also last long enough for you to use them as daily drivers. I definitely wouldn't drive around on drag radials that only last for like 5k miles and provide limited cornering ability... these tires provide the best of all worlds.
