Conceptua Tuning Rear Subframe Uprated Polyurethane Bush Kit
Improves Handling- Helps Eliminate Subframe Knocking
Superpro Uprated Polyurethane Bush Kit for the Rear Subframe on S14a 200SX's. This kit contains 2 x 69.5mm O/D bushes, and 2 x 80mm O/D bushes- so there is enough to do the entire Rear Subframe.
The stock Nissan rear subframe bushes contain silicon-filled Rubber Bushes. Even on stock HP S14's, the stress of putting the power down twists the rear subframe- punishing the subframe bushes. The rubber perishes and the silicon leaks out- this leaves an air filled void that can lead to vague handling and a loud knocking from the rear on really bad examples! The Durometer (Hardness) of this supplemental Polyurethane Bush Kit has been specifically designed to give a significant improvement on the handling characteristics of the original Bushes.
