Video description
Upgrade your Subaru’s rear-end stability with the Whiteline KDT938 Rear Subframe Mount Insert Bushing Kit! Designed to work with your factory rear subframe bushings, this insert kit helps reduce excessive compliance, also known in motorsport as “lost motion,” for a more controlled and responsive driving experience.
During cornering, unwanted movement in the rear crossmember can affect vehicle stability and handling precision. Whiteline’s KDT938 inserts are engineered to dramatically reduce rear crossmember misalignment and movement, helping deliver a more positive, predictable feel from the rear end when pushing your vehicle through corners.
With a straightforward installation that works alongside your original bushings, this kit is an excellent option for DIY enthusiasts looking to improve handling without replacing the entire factory bushing assembly.
