Fits all 996 The rear suspension of the 996 has been designed to be the best Porsche suspension to date. But for track duty, the rear rubber subframe mounts still need to be replaced with solid aluminum bushing in order to maximize grip. Machined to be a light press-fit, these bushings are easy to install with a vise or arbor press and allow the suspension subframe to be held solidly to the chassis, thereby improving performance. Sold as a kit of 12, as shown.
