I get marred easily once i try a product and under real world testing it failys or performs very poorly.
My expericance starts with a customers 91 300 zx with the same FZ-4 tires. It is noisy as hell with them on. I also keep getting the rear end loose much more often than needed. If you drive a 300 it is a really heavy car with moderate power( non TT). Compared to another 300 i have driven also with 18's but falkens it was a dramatic improvment in stability of the sidewall,road feel, noise . Toyo makes great tires the RA-1 ,T1-S but the price point and the return are completly dependent on the tires demands. They make a basic tire for summer and that is there fz-4s. You will never see that tire on a track,car shows maybe but only on a car picking up points when toyo sponsers the event for a few extra points.
