I have an 04 a4 gto with the IRS in it and had a though that I would like pro and con opinions on.
I have a free ford 9" out of a 66 mustang laying here in the garage and was thinking about fabbing up a 4 link or ladder bar setup to mount it under the goat for extra strengh, less weight and more gear options....was thinking 3.90's.
anyone have any thoughts, or done this swap?
