This package allows you to build your own rear bushing package to cover the parts you want to replace. As these cars age, they require a number of suspension bushings to be replaced. Bushing replacement not only keeps the car in its top form, it also makes the car safer. Depending on the work, it may be logical to replace all of the bushings in the rear suspension (there are 19 total). This is especially true if you are pulling the subframe out to do the floor reinforcement or if you're doing a diff install. Turner Motorsport is a big believer in using rubber bushings for street cars (with the exception of solid subframe mounts, see further below). Urethanes, Delrin, or aluminum are generally good for reducing compliance and limiting deflection - attributes that don't really work well on roads filled with potholes, railroad crossings, cracks, and expansion joints. The rubber bushings maintain the factory ride/handling traits that won the E46 praise all over the world. Every bushing will need maintenance or replacement at some point and rubber has proven to last the longest and need less maintenance than anything else, even urethane. And unless competitive driving is your goal, the harder materials are only a gimmick.

Any major overhaul of the rear suspension should include new subframe mounts. The worn rubber mounts contribute to rear subframe-floor failure when the deflection in the mount is transferred to the chassis. Rubber mounts are only OK for street cars that don't see aggressive driving, autocross, or track use. For any enthusiastic driving, we strongly recommend our solid aluminum subframe mounts even on the street. They have zero deflection and will not contribute to rear floor failures. And if you leave rubber in the rest of the suspension your ride comfort will not suffer.

Individual Item Descriptions:

• Trailing Arm Bushings and Limiters (33322228153 and TSU9990001) - our OEM rubber replacement trailing arm bushings (RTABs) are a perfect fit and help maintain rear toe alignment. The Limiters prevent premature bushing wear.
• Rear Inner Control Arm Bushings (upper 33321092247 and lower 33326770824) - new stock inner rubber bushings for the upper spring arm and the lower camber arm. These do not wear out very quickly but should be replaced as a 'While you're in there...' job.
• Rear Outer Control Arm Bushings (upper and lower) (33326775551) - new stock outer ball joints for the upper spring arm and the lower camber arm. These are the standard ball joint design and last a very long time. Check for play with a pry bar and replace as needed.
• Rear Shock Mounts - Choose from several types of RSM upgrades. If your mounts have not been replaced in the last 40,000 miles, now is the perfect time. Skip this option if you recently replaced mounts or already have an upgraded mount.
• Differential mounts (33176770788 and 33176751808) - Now is a great time to replace the rubber-isolated mounts. This is another low-wear mount but it can be changed easily, and is a low cost item. Solid diff mounts are streetable with only a minimal increase in NVH.
• Rear subframe mounts (33316770783, 33316770784, 33316770781 x 2) - The heart of the rear suspension, the subframe (or carrier) mounts located the entire rear suspension to the car. There are four mounts in total and bolt up into the rear floor. Worn subframe mounts are one of the leading contributors to rear floor-subframe failure. As the mounts flex, so does the sheetmetal of the chassis, which will fatigue the sheetmetal and crack the spot welds. Therefore, replacement of the subframe mounts is critical and a must when doing the subframe reinforcement or repair. Solid aluminum mounts are streetable with no increase in NVH.
