Step up your 1993-1989 5.0L Mustang with an awesome upgrade: the QA1 (HK23-FMM1) Level 3 Handling Suspension Kit with Pro-Coilovers!

This K-member is 50 percent lighter than the factory K-member and is made in the USA. QA1 designed the lower control arm brackets to be raised, which corrects roll center when your Mustang is lowered. This K-member also maintains optimum anti-dive geometry with minimized bump steer issues. Ideal for street performance and autocrossing applications, this K-member gives you the ability to change the steering geometry with stainless steel steering rack relocation inserts. You can choose to run the steering rack in the stock location, or raise the rack for maximum performance.
