Front Upper Spring Perch With Bearing - E38, E39, E46 M3, E60 M5
(more info)
If you are removing or changing the front struts or springs or replacing the upper strut mount, NOW is the perfect time to replace this upper spring perch. BMW calls it a "upper spring pocket with axial cage bearing". It's really the upper spring plate with the bearings sandwiched between two plastic collars. The bearing insert is a common wear item becoming noisier, and gritty, or will just fail completely. You won't feel that they're bad from driving the car but you may hear clunking or popping sounds from the front struts. You can replace the rubber mounts on the car but don't leave this part out! It may be just as worn and you won't want to put them back in the car. These are sold individually, so be sure to get two for your car.
Upper Bearing Perch Applications:
1994-2001 E38 740i, 740iL, 750iL
1997-2003 E39 528i, 530i with EDC - electronic damping control - suspension only

Rear Outer Upper or Lower Trailing Arm Ball Joint - E36, E46, X3, Z4
(more info)
This ball joint is used for the upper rear trailing arm bushing on ALL E36, E46, E83 X3, and E85 Z4 cars. BMW also used it as the lower bushing on most M cars. It makes a great upgrade on all non-M cars where BMW used a rubber bushing at the lower position.
This sealed ball joint is one of the best things about the rear suspension - it functions extremely well and lasts a long time. And it can be used as a replacement for the existing bushing without any further modification. The non-M cars used a solid rubber bushing for the lower arm (camber arm, wishbone) which does not last very long and relies on bushing deflection (twist) during suspension motions. The ball joint inside the upgraded design is much more effective during this suspension movements as it does not bind or deflect. And because it's sealed with rubber it will last a long time and remain quiet and maintenance free. Most customers report that after installing or "upgrading" to these bushings the rear end of their car felt much more stable.
Price is per bushing. Left/Right and Upper/Lower are the same part.
This item fits the following BMWs:
1992-1998 E36 BMW 318i 318is 318ic 323is 323ic 325i 325is 325ic 328i 328is 328ic M3

Rear Shock Mounts (RSM) - HP Aluminum/Rubber - E30, E36, E46, Z3, Z4 (Pair)
(more info)
 These are the best rear shock mounts that we have found for the E30, E36, E46, Z3 & E85 Z4! Featuring CNC-machined billet aluminum mounting base with a replaceable urethane bushing (replacement bushings are just $15 and are changed in minutes!). These mounts are excellent for either street or track because of their low NVH (noise, vibration, and harshness). Plus, the superior design will far outlast the life of stock mounts - maybe even the car itself. You'll never think twice about your shock mounts again! These shock mounts are a direct replacement of the stock mounts so they fit all shocks with the BMW-standard 10mm shock shaft, including all factory and OEM shocks (Boge, Sachs, etc), H&R coil overs, Bilstein shocks and PSS, PSS9, PSS10 coil overs (except the B16 Ride Control Kit). This is sold as a package with new shock mount gaskets, washers, and Nyloc nuts.
This item fits the following BMWs:
1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is 325ix M3

Rear Subframe Bushings/Mount Set - Rubber - E46 M3, Z4 M
(more info)
Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.
Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor). The rubber bushings help isolate bumps and impacts and are quiet. They are also a perfect fitment and require no maintenance.
This item is a set of 4 Original BMW rubber subframe mounts. Individual part numbers - 33 31 2 283 573 (left front), 33 31 2 283 574 (right front), and 33 31 2 283 419 (left and right rear, x 2).
Applications:
2001-2006 E46 M3, M3 CSL coupe, convertible
2007-up Z4 M Roadster, M Coupe

Rear Subframe Bushings/Mount Set - Turner Solid Aluminum - E46/E46 M3, Z4/Z4 M
(more info)
The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.
While our Delrin-Aluminum subframe mounts conform to various racing series these all-aluminum mounts are the ultimate in reducing flex and deflection. The rubber stock mounts, and the Delrin mounts to a small degree, flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. These fully solid aluminum mounts have absolutely zero flex to them so they will not contribute to rear subframe issues. The Turner E46 Reinforcement Kit is still recommended.
These solid subframe mounts were designed for racing use only, where we won several sports car championships in the Grand-Am Cup series. These subframe mounts are over-engineered to be a major improvement over the stock subframe mounts not only for performance but also in strength as well. The aluminum is CNC machined for a precise fit and minimal weight. One front bushing is slotted to allow for BMW's manufacturing tolerances. Professional and experienced installation is required.
This item fits the following BMWs:
