Energy Suspension Subframe Bushings
A subframe bushing is found at the mounting point between the subframe and the body. Most OEM subframe bushings are made of rubber, which over time begins to wear and crack. With a failed subframe bushing, noise and vibration become a major issue for both the driver and the passengers. The subframe bushings responsibility, besides mounting, is to dampen road noise and vibration from entering the cab. So once these bushings go, your quiet smooth ride is in trouble.
Energy Suspension's Hyperflex polyurethane is a much more durable material for subframe bushings. Not only do these bushings maintain the mounting alignment very well, but polyurethane does not crack, distort, rot, or wear the way rubber bushings do. With more durable material, there should be an increase in NVH. But there is also a performance boost to consider! With polyurethane subframe bushings you can effectively eliminate wheel hop giving you a faster launch time whether from a starting line or a green light.

Energy Suspension 7.4102

Good product, fit well. I used these on a 95 Infiniti Q45 (same suspension as a 300zx). They do transmit a bit more noise through the suspension into the cabin but nothing that is overly annoying.

The material provides a firmer ride, which is great for handling and adds more of an authentic sports car ride. Material can be difficult to work with even with specialized tools, such as a ball joint press, whole saw, drill, etc. I think the manufacturer should improve the picture/diagram quality. Tourque specs should have been included in the instructions.
