I'm installing Powertrix coils in a few weeks. Not necessarily for lowering (original Susp. in my 92 TT) more for comfort. I may lower an inch possibly 2. Do i need the new tension rods and adj. control arms or will I be okay with just the coils?

 

If you go 2 inches I'd think you'll need adjustable control arms or an eccentric adjuster to get camber in spec. Less than that depends on how much camber you want to accept.
