Hi Greg, I will be looking for some replacement track tires this year. I may be interested if you think they would be suitable for my car. I have an early '71 240Z, that I use for track days such as NASA's HPDE Program. It is equiped with Tokico Illumina's, MSA performance springs, 1" sway bar front, 7/8" rear bar. Toyota 4x4 brake upgrade. Right now I am using Hankook Z211's size 225/50/15. They are mounted on 15x7 rims. Was considering going with Toyo RA1's or R-888's. Are the Goodyear's size 225/45 also? So, what's a nominal price? Funny, I was just reading about "take offs" in Grass Roots Motorsports, and it sounded like an interesting idea. Especially with today's economy. Thanks for thinking of us! Marty
