GKTECH Z34 Rear Subframe Collars are used to eliminate axle chatter and tighten the rear end allowing for more precise vehicle control in harsh driving conditions. The stock bushings are designed more for comfort than performance and by filling the voids in the stock subframe bushings the subframe becomes much more "one" with the car. Noise is not drastically affected compared to solid subframe bushings and these inserts are much easier to install than solid subframe bushings.
