Last october at Putnam Park I saw two miatas and one 944 each go thru a set of new Hoosiers in less than a weekend. Since then, Hoosier ask the 944 driver to send his back to Hoosier and they gave him another set. Recently, we got 15 heat cycles and over six hours of track time out of one set of the new Hoosiers on a World Challenge BMW, and there was still some life left when we took them off. Is it the difference between World Challenge suspension (JRZ RR shocks) and Improved Touring suspension that made the difference, or was it just a bad bunch of tires at Putnam Park? I hope it was a bad batch of tires at Putnam!
