I will get Gary to comment on the Tires....he has been talking directly with Goodyear on this....and I believe that those bluestreaks are racing tires with very little to no tread on them...the picture shows some but mine are like regular tires and have alot of tread (basically they are the rain tires
so you are correct they still make them blue streaks but!!!! you don't want to be caught anywhere in the rain with them and on the street I get rocks like crazy you will get them so bad you can say goodbye to your paint.
Dan I think when I got the tires they were around $220 a piece and a bear to mount (my tire shop hated them) because you can't use and lube on the rear tires ...horsepower + grip + lube means tire spins on rim and thats a big problem...they mount alot of racing tires and have had people return to them PO'd because they step on the gas and burn rim
I do know that there is a set that shelby sells but I believe they say eagle and if I am correct they are a taller tire and if you go lock to lock will rub the inside of the fender.
