I recently purchased Continental ContiSportContact3 tires for my 05 at Tire Rack....215/40ZR17 fronts ( $172. ) and 255/40ZR17 rears ( $182. ) and they perform great! I tracked with them two weeks ago at Putnam Park, IN at a Porsche drivers education session, and they worked well. I have the ContiSportContact2 on my 911 C4S which lead me to purchasing for my NSX. I had a 96 NSX and purchased the recommended Bridgetones which also performed good, but I only had a couple of years and 3K miles, without being tracked. Please note that they are now discontinued, although Tire Rack had them in stock!
