Joe, this may help you! As I am in the same boat and have done exceptional research......I have come to this, regarding the 15's......the top of the line on traction, wear and ride.....is the Yoko's.....they have the newest compound (silicon) and they are priced well! But, not too far behind are the Dunlop Qualifier GT's. Both these tires are T rated (up to 118). However, when it comes to ratings.....remember that with this type of car and weight, you can still be fairly safe for a bit at higher speeds........Next would be either the Goodyear GT II or the BFG Radial T/A. These are rated S (112). But again, not exactly an exact science on these cars! I hope this helps........BTW.....I think I will be going with the Dunlops......as they are good performers, good rating and you can put the white letters on the outside, if you like that look! Many feel that to put the Yoko (outlined in white instead of solid) on the outside is not as preferred as the tires are not so politically correct, whatever that means! Up to you, but wanted to have you benefit from all the info I have accumulated recently.
have a good one.....................Fred
