A BMWs sub-frame is the heart of the suspension - as the subframe twists and shifts under load all of the suspension mounting points also move. The rear suspension feels loose and lacks precision. As rubber or hydroelastic bushings wear the bushing deflection gets worse. If you have a highly tuned 335i/xi you're putting even more strain on weak bushings. The solution is a stiffer and more durable material. Even BMW has moved to solid mounts on the F10 M5 and F8X M3/M4. These fully solid E82/E90/E92 aluminum mounts have zero deflection - the subframe does not move at all. The rest of the suspension can work as designed and maintain the proper alignment and motion ratios. The driver will notice the difference as the car is more stable and the handling is more precise.
Although we designed these for use in our racecars, they can work on the street so long as the driver can tolerate some additional noise, vibration, and harshness. These mounts are CNC machined in the USA and made with high-grade aluminum. The set is for all four subframe mounts.
These solid rear sub frame mounts fit:

Help preserve the structural integrity of your BMW E82 1-series, or E90, E91, E92, or E93 3-series with these weld-in strut tower reinforcement plates. Deformation of the front upper strut tower has been common problem, especially in race-prepped cars, cars with lowered suspensions, any car that sees track use, or BMWs driven on rough roads. The strut tower deforms from suspension bottoming out, forces generated by the spring/shock assembly, and that forced concentrated in a relatively small area on the strut tower. The strut tower will exhibit deforming by cracking (especially around the stud holes), or "mushrooming" where the tower takes on a dome-shaped top instead of being flat. By thickening the sheetmetal material of the tower, you are making it stronger and more robust to prevent deformation. While the E82 and E9x cars are newer and better made than the previous E36 and E46 cars, any suspension modification or track use will make the new cars more susceptible to this problem.

Our renowned TMS adjustable front sway bar / swaybar links for BMWs are now available in custom lengths, making them easy to order for any aftermarket or custom suspension setups. Simply measure for your ideal link length, and order the links with the best length range (below). Each sway bar link has a 10mm diameter mounting pin/stud, which is the typical factory/stock size for a universal fitment. These are sold by the pair, and each set includes two matching sway bar end links.
These end links offer the quiet operation and long life of "stock" BMW end links, but with the strength and adjustability of rod-end style sway bar links. These sway bar links can be used on a wide variety of BMWs and aftermarket BMW suspensions. When measuring, please consider that the length ranges of our Custom Adjustable end links are measured from the center to center on the end link mounting stud / pin, as shown in our diagram.
Note for E9X M3: the unique mounting on the M3 strut requires a set of our adapter seats (#TSU9912AF9). You can add them with your links from the menu below.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.
By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.
Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Rear shock mounts are tasked with securing shocks while absorbing noise, vibration and harshness that would otherwise be associated with a solid mount. Factory rubber bushings are a compromise between a cushy ride and responsive handling.
Powerflex polyurethane rear shock mounts are firmer than OEM bushings, resulting in better handling, a more responsive rear-end, and more efficient suspension articulation - all with minimal sacrifice to ride quality.

We've installed these on our own 2008 M3 sedan project car (the white car pictured) and love the way these spring feel. They transform the handling into more of what (we feel) an M car should feel like -- sharp cornering with only a small sacrifice in ride quality. The ride is still very compliant and well suited for city streets, keeping the ride quality very close to the stock ride comfort� even with 20" wheels! Now that's a well engineered set of springs!

M3 upper and lower control arms are a known upgrade for non-M E82 and E9X chassis. But our Monoball Thurst Arms are even more of an upgrade over the stock M3 arms. This package bundles the Turner Monoball upper thrust arms with the stock M3 lower control arms. If there's one big fail point in the E82/E9X front suspension it's the thrust arms. The front inner thrust arm bushing is filled with dampening fluid that leaks over time. Once it's gone the bushing has the strength of a rubber band. Even though we sell two types of upgraded rubber bushings there was still room for improvement. For someone looking for superior performance and longevity these sealed monoball bushings are the best out there.
The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings, including the M3, move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. And when worn out, performance suffers. Our monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings.
The lower M3 control arm bushings use a similar sealed monoball bushing instead of rubber. This package gives you monoball precision and performance with OE-quality components.

These bushings replace the stock rubber bushings and offer a better driving feel, increased lifespan, and better wheel alignment.
Rubber bushing allow for a lot more movement and are more susceptible to wear and tear from spirited driving and harsh weather conditions. Polyurethane is much more resistant to wear and is stiffer, reducing the total amount of movement that would normally affect the alignment negatively.
