I'm sorry, I didn't read your post as well as I should have. I have NWOR springs at all 4 corners, NOT northwest rears up front. That would probably make a big difference as the added stiffness would be welcome up front since usually OEM rear springs are wayy soft. That might work out real well. I might even try that since I was put off of RUF since around here (AL) they and chevies are too soft.
