I show video of my independent rear suspension before and after installation of the Kelltrac Posi Loc System on my Ford Mustang Shelby GT500 CFTP as well as the step-by-step installation process. Posi Loc is in reference to centering & positively locking the IRS subframe in relation to the body. This system works on the 2015-2023 Mustang and combats the subframe wiggle/deflection/bounce the IRS experiences during hard acceleration, turning and braking. The suspension is still free to travel normally. If you would like to firm-up your rear end, this is a worthwhile cost-effective mod!
