My friend is planning on joining N2 and doing track days with me this year. He asked me if D214 will work and be any good on the track? I could not answer any of his questions because I know nothing about these tires. He also wanted to know how they compare to the Q3 that I run on the track? He will be riding in the Intermediate group and is a very decent rider. Also the D214 tires are new with less than 100 miles on them. Thanks for any help I can pass on to him...Scott 71 I told him to buy some Q3 but he really does not have the extra $$$$ right now.
