A lot of clutches have came out since I last had to do one for a mustang. I still have the stock clutch on my car but im going to replace it once I get back from Iraq when I put on the Charger. Im looking at either centerforce or a Spec mabe ACT but havent heard alot of them. With the followings mods which one would be the better choice? Only new mod was a Boral Cat back the rest is still the same. Thanks
