I was wondering if anyone has had any experience in how the federal 595 rs-r in 215/40/17 compares to the dunlop direzza z2 star spec? The federal is much cheaper and I was wondering if the price savings is worth it . My main concern is GRIP, I want grip to prevent wheelspin in first and second. I don't care too much about the noise, unless they are way more noisy. I do plan on taking it to the track on occasion, but I won't compete. These will be mounted to motegi mr125 wheels, 17 x7.5. No auto cross. My car is cobb stage 2. Thanks for your help.
