I am looking for some input on what other people have used for competition tire. I have a 93 civic ex with a pretty modded out SOHC motor: I/H/E , Zex cam, Zex valve springs, Titanium retainer, MSD ignition, Chipped ECU, Fuel system upgrade comptech pump, Aem rail and regulator. Anyway my best time at the track with Potenza S-03 pole positions is a 15.9 at 89mph, with a crap 60 foot time. I am looking for a competition tire that will help this launch get off a little smoother. I know the car has it in it, it takes out Si's and some gsr's all day but at the track the tires just say no. thanks if anyone else has this setup or somthing like it post your times, thanks
