Re: lowering a BA
I lowered my BA XR6 and didn't need a c&c kit. Done almost 20,000k with new springs and tyres are wearing perfectly evenly.
I had my springs manufactured and installed by Whiteline Suspension, progressive rate spring. Car handles and drives like a dream, great control, less body roll (could be from new adjustable sway bars), and i think the ride is smoother than it was out of the factory. Lowered the car 35mm.
5 speed or Nothin' Mercury BA Falcon XR6 Manual with 18's, Whiteline Lowered Springs, Adjustable Sway Bars, and Herrod Exhaust......mmmmmh
