In the end, I hope to be putting around 650 ponies to the back wheels of the ol' stang. My question is how much abuse will the stock k - member take before something goes wrong up there? it's a 93 coupe, the chassis pretty stiff; 8 point roll bar and sub frame connectors. I realized it would probably be to my advantage just to switch it out (to a tubular k-member), but I really don't want to shell out the benjamins for it. Thinking I could stiffin the stock unit by welding some thick metal along most of it for support if i needed to. But im really wondering how much it will handle "as is" from the factory? I'm just going to be running 17" low profile tires on it, not drag slicks or anything. I'm not going to beaing taking to drag it probaby at all, but may get into some road course type racing some day. I will probably just end up getting the tubular k member in the end. If anyone has some testimonies about what a dramatic improvment it has made I would like to hear. I appreciate any input you have on the subject
