Alright guys..I have a 2002 SVT Focus. the 17 inch wheels arent cutting it at the track. So, i am thinking about grabbing a stock set of 16 inch focus wheels, and putting some drag radials on them..problem, the only size thats offered in a 16 is a 255/50/16R. btw, thats focking wide as hell... any suggestions? i would like to run a 15 but calipers wont allow me to do so.. anyone know something I dont, and drag radials wont  anything up on my car will they?
