Just want to say THANK YOU for getting my set of Kumho's to me on such short notice.
E-mailed Luke Friday late afternoon asking if a set of Kumho's (275x40x17 and 315x35x17) could be heat cycled and arrive at my home the following Thursday. Luke called me at home Friday and I ordered the tires. They arrived on Wednesday.
Mounted the tires on the Grand Sport wheels and went autocrossing Saturday with Norther New Jersey SCCA at Englishtown. What a great improvement over the stock sized B.F. Goodrich R1A. The Goodrich were a big improvement over the stock Goodyears, but going to the Kumho's was a larger improvement. My wife also drives and she noticed the difference after the first two corners.
If anyone has any recommendations the tires pressures I ran the first time were 36 psi front and 33 psi rear. This Saturday is Corvette day at Englishtown. NNJR will be running the autocross. Will try increasing the front pressure by 2 psi and keep the rears the same. These tires have so much more feel than the Goodrich. When we improve will graduate to Hoosiers.
