tk,

i'm going to assume you're talking about the cobra's in the vintage race. if so, you can call shelby enterprises in california. this is where i get mine. the are "short track" stock car tires. they are track only not for street use. there are two differenet compounds for the front tire. the softer compound with more grip and less life is 2994. the tire with the harder compound, less grip (vs 2994) and more tire life is 2272. the rear tire compound is 2373. a set of 4 should be less than $800. in the denver area i can buy them for about $110 per tire. i think shelby prices are similar. i buy mine from shelby enterprises thru the children's foundation.

these tires have been compared on the track with the hoosiers. based on testing with the challenge cars, the goodyears have just slightly more grip. if i remember correctly, the cost of the goodyears vs the hoosiers is a bout the same over the life of the hoosiers. meaning, the goodyears won't last as long, but the number of goodyears you'll go thru for one set of hoosiers - the cost will be about the same.

hope this helps
