Updated in 2020 to provide additional reinforcement! The E46 rear driveline and suspension are very similar to that of the E36. An unfortunate side effect of this is that the E46 also shares some of the same problems as the E36. One of these problems is the rear mounting points for the subframe, which can rip out from their spots in the sheet metal. This happens because the rear differential transmits the torsional load from the engine through the subframe, then into the chassis. This constant loading and unloading weakens the sheet metal and causes it to fatigue and separate from the chassis. BMW tried to fix this problem in the E46 by placing a cross member on the front two mounting points of the subframe. This cross member keeps the front mounting points from having problems by placing the bushing and the stud in double-sheer, thus reducing the twisting action on the sheet metal. The unfortunate side effect of this is that the load from the front of the subframe now gets transmitted to the left rear of the subframe. This is where we have seen many failures of the chassis on low mileage street cars and race cars. BMW has also tried to prevent the issue by injecting foam into the open space between the underside of the chassis and the top of the trunk. This seems to work but that does not address the issues of the spot welds failing on the sheetmetal. It can also make any additional work there harder and almost impossible to weld against. Our reinforcement kit has proven over and over again to be effective and the easiest to work with in the long run.

This product reinforces the chassis sheet metal at the subframe mounting points. We do this by thickening the metal and distributing the load over a larger area. This kit will save time when repairing the chassis, and is also strongly recommended as a preventative maintenance item.

These are the BMW factory chassis reinforcement plates that came on the E36 M3s (some very early 1994-production M3 models may not have had them). This reinforcement should be done on all non-M E36 models especially when used in track/autocross situations. The kit is a set of 4 plates that are added to reinforce the rear subframe chassis mounts. BMW discovered that over time, due to the bending of the rear of the chassis in conjunction with the movement allowed by the rubber bushings in the rear, the chassis mounting points for the subframe would flex, weaken, and if left unattended, rip out of the chassis. The stock mounts are basically a flat plate with an internally threaded tube that are welded to the chassis. The flex of the rear subframe causes the threaded tube and mounting bolt to act as a lever arm at the point where the flat plate is welded to the chassis, weakening the surrounding sheet metal. Due to the direction of force of the torque applied by the drivetrain on the subframe, the first mount to rip out is the passenger�s side front mount, followed by the drivers side rear mount. Having these plates welded to the underside of the chassis significantly stiffens the mounts and stops the weakening of them.

In order to weld these plates in, the rear suspension, rear subframe, exhaust, and driveshaft must be removed. It is also strongly recommended that the back seat, rear interior, trunk interior, and fuel tank are removed and all fuel lines are capped to reduce the fire hazard while welding.

Made in the USA A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

Made in the USA 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.

These are mounted on the underside of the strut tower and need to be welded into place.

Made in the USA The motor mount area on a subframe is one of those easily-forgotton areas that may be hiding a serious problem. The subframe on the E36 has a gusset ('ear') welded on for the motor mounts. These gussets take the stress of the motor mount as the engine torques (more upgrades = more torque = more stress). Worn motor mounts only transfer more stress to the subframe. Unfortunately, the gusset is not well-reinforced from the factory and cracks can develop along the welds and the gusset begins to collapse. A total failure of the guesset will shift your engine to the side and forward, taking out many other components along the way and leading to a very costly repair.

The next time you replace the motor mounts, oil pan gasket, checking your oil pump nut, or any other time you drop the front subframe, you should install these reinforcements. This kit comes with steel reinforcing plates that are welded to the underside of the guesset as well as plates to close off the bottom of the gusset for extra strength. Instructions included (or see the link below).

Made in the USA E36 cars with swaybar upgrades will develop cracks where the swaybar bushing mounts to the subframe. The problem becomes worse for cars that are tracked or drifted. Because the swaybar tab is un-reinforced from the factory, you can end up with flexing and twisting which will eventually weaken the welds and snap the tab from the subframe. By welding in this reinforcement you can prevent the mount from twisting. This will go a long way towards preventing a bothersome repair down the road.

Made in the USA This product reinforces the metal swaybar link mounting point on the rear trailing arm. The sheet metal breaks off the trailing arm due to the constant up and down loads being placed on the trailing arm from the swaybar. Problems increase when larger sway bars are used. This product eliminates the problem by thickening the sheet metal and triangulating the mounting point. A good time to install this kit would be when you are doing any rear suspension work, exhaust, or even if you are just doing a differential fluid change. This part requires welding for installation.

Made in the USA The BMW E46 3-Series chassis is one of the most rigid and well built BMW chassis to date. Even so, it still has some of the traditional BMW weak points. One of these is the rear sway bar / swaybar mounts. From chassis to chassis the problem has not been identical, but all the damage we have seen has been related to metal fatigue. The metal fatigue is due to the constant twisting and side loading of the sway bar. These forces on the sway bar will cause the mounting points to fail over time. The failure can happen faster with sway bar bind due to improper maintenance of the bushings. However, proper sway bar bushing maintenance does not totally eliminate the problem. In the case of the E46 the sheet metal for the bushing bracket does not have enough material to support the loads being transferred to the subframe. We have designed the reinforcement to strengthen and redirect the load to stronger sheet metal. Requires Welding. Does not fit M3.

Made in the USA Every E30 M3 that comes into our shop gets the front swaybar tab inspected. This is such a common problem but with an easy fix. If left to worsen you may be looking at an entire strut housing replacement. Fix it now with these reinforcing plates and a little welding! Not only will modified suspensions put stress on the mounts but age will reduce their strength as well. Reinforcing the swaybar mount to the strut will keep your swaybar geometry in spec and prevent a costly and ugly repair.

Like the E36 before it, the front strut towers on the E46 are notoriously weak. Under normal driving conditions with a stock, fresh suspension it is unlikely that you will ever have a problem. But with an upgraded street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. Look for 'mushrooming' or deformity around the holes for the three mounting studs at the top of the strut tower. The sheetmetal around the holes should really be flat and square. Poor shocks or stiff suspensions will actually cause this sheetmetal to pop up.

These factory BMW reinforcement plates will help disperse the energy and save you from costly repairs in the future. A strut brace also helps to prevent this but these plates are designed to reinforce the strut tower from the bottom. The install over your strut mount or camber plate and simply add thickness (strength) to the strut tower. They can be sandwiched in place and do not require welding.

This item fits the following BMWs:

2001-2006 E46 BMW M3*
* - The stock M3 upper strut mount already does a good job of dispersing the loads of the suspension. These reinforcement plates will fit a stock mount for added strength but need to be trimmed to fit inside the strut tower. The are very strongly recommended for all M3s with coil over suspensions because aftermarket coil overs typically have a smaller surface area for their strut mounts.

Includes RTAB limiter, rear shock tower reinforcement plates and BMW Strut tower plates. If you already upgraded your suspension but are looking for the finishing touch, this kit is what you need. The BMW front strut mount reinforcement plates reduce the risk of the shock tower mushrooming and cracking. The rear shock mount reinforcement plates reduce the risk of the rear shock mount area tearing and deforming. The Delrin rear trailing arm bushing limiters reduce the movement that the RTAB's can make resulting in a tighter rear suspension and with less moment prolongs the bushing life.

M7 Strut Reinforcement Plates 53-510101 are the ultimate solution for MINI owners facing the common issue of strut tower mushrooming caused by heavy impacts from shocks and low aspect ratio tires. Over time, MINI's shock towers can develop a convex shape, disrupting suspension alignment and leading to a noticeable pull to one side. The M7 Strut Reinforcement Plates (SRPs) address this problem by reinforcing the sheet metal and shock top plate, creating a durable surface that resists bending, even during hard impacts.

Designed specifically for the R50 Base Model Cooper, the R52 Convertible, and the R53 Cooper S, these SRPs are an essential upgrade for any MINI enthusiast. Constructed from CNC machined billet aluminum and black anodized for durability, the 1/2" (13mm) thick plates cover the entire surface of the strut tower, distributing loads evenly and providing peace of mind.

Whether you drive your MINI daily or push it to the limits on the track, M7 Strut Reinforcement Plates offer a cost-effective preventative measure against expensive suspension repairs. Easy to install in less than 20 minutes, the SRPs use the stock nuts for mounting and come with instructions that also guide you through fixing existing mushrooming.

  • Prevents strut tower mushrooming
  • Constructed from CNC machined billet aluminum
  • Black anodized for long-lasting durability
  • Covers the entire strut tower surface
  • Designed for R50, R52, and R53 MINI models
  • Easy installation with stock nuts
  • Made in the USA

Condor's Rear Trailing Arm Pocket Reinforcement Kit is one of the few kits in which the plate is not cut in the shape of a "C". A lot of companies cut them with an opening in order to have less waste when cutting. Their plates are fully connected all the way around making them stronger. This is a must-have reinforcement. The front mounting point of the rear trailing arm is a known area of failure on track driven E36s. Condor's 2-piece reinforcement plate kit reinforces the stock pocket bungs to prevent failure. Welding is required, includes rosette holes. *Does not fit 318ti.
