I ahve old school weaponR's (no helper spring) and they're 450lb/in front, 350 rear. Using kyb agx's for a 3rd gen teg, I love the setup. I leave the shocks all the way stiff all the time, threw on an Si rear sway bar, and it's great. Most people who drive the car love it, and think it corners amazingly, and I agree, but I plan on eventually getting a fat front sway bar (the S didn't come with one) and getting a bigger rear sway bar. After that, strut bars about the only other thing you can do. I have mine lowered about 2 inches with 205/50/15's and have never had any tire rubbing issues. Rolled fenders? **** that! cut out the lip, and seal it with underbody coating.
