CivicSiRacer...good call on the tires...I completely forgot about to mention that. Doh! For whoever is reading this, he's right. Tires alone can drop your brake distance dramatically...think about it. You don't have to change lugs or anything for the basic civic EX wilwood kit, but you'll need atleast...ATLEAST 16" wheels, (guy who's EK I drove around Nelson's, had a set of old school Panasports, 16's...and they came DAMMMMMMN close, with rotor diameter, and with the caliper/spoke clearance...that's offset though.) If I remember correctly, that kit comes with 12" rotors. My Stoptechs are 13's, and even though my Zigens are 18's, I KNOW a 17 would work. if you get the right offset 16, with the willwoods...you should be good to go. If my pictures looked odd with the 5 lugs, it's cause I converted to 5 lug, and the StopTech kit is actually an Integra Type R kit. HUGE pain in the ass. I'd say it was a waste of time...but man I love it. Summit's website has that Wilwood kit for 639...but if you know someone with a vendor's license, and you set up a wholesale account (their wholesale company is inhouse, called "A-Tech") You should be able to get the kit for well under 600...with stainless lines. Once again...bargain kit. Good luck with that car by the way.
