I used the NM12 TBird IRS under my FFR Cobra, basically because it has much less unsprung weight vs the 8.8 live axle and will give a better ride and is more compliant over irregular surfaces. However, the design of the later 2015 Mustang IRS is a much better design and can show handling improvements over the NM12 design.
