How do these inserts improve the feel of the rear end?

These inserts fill the voids in your original subframe bushings. This reduces unwanted movement or 'lost motion' in the rear crossmember, leading to a more direct and connected feel from the rear of your car, especially during cornering.

Do I need to replace my original bushings with this kit?

No, this kit is designed to work with your existing factory bushings. The inserts are installed into the original bushing housings to reduce compliance without requiring a full bushing replacement.
