Soap Box thanks so much..i have money to burn i guess... just don't want to go over a thousand for the set of tires...want to feel what the car feels like on slicks(never been on them before at a track)..i put on private track days and my buddies and we take out our cars and film and what not ...also do alot of data logging to help my driving skills improve. I am very new to the slicks and those types of compounds your input is much appreciated. I was thinking the nto1 because there only 550 for a set of 235's 17's and the r1's on the other hand are only 110 bucks more for a set.. advice? thoughts? again this is just for me and learning how the car reacts on a sticker tire then a re070 bridgstone and re01r bridgestone. I am very new to running different tires all the time..i finally can afford to try things out and again all your advice and input is really cool !!!
