To narrow or not to narrow that is the question (rear end that is). Its either flare it or narrow it cant decide. Basically I got tired of all the broken half shafts and did a solid axle swap along with the 5 lug swap up front. Just need to make the 35mm spacers for the rotors so I can keep my 4x4 calipers. Now before i get the IRS is way better than solid axle answers I simply prefer a solid axle. My engine is just a 5.3 with 160k miles small cam and a t56 nothing special but deffinately a half shaft eater though. Wheels I believe are 2006 6 cylinder mustang rims got a good deal on them. New axle is an 8.8 with a triangulated 4 link and coil overs. Unfortunately the exhaust I just made a couple months ago must now be redone due to the new setup.
