BMW E30 M3 Chassis Reinforcement Kits & Parts

BMW E30 M3 Chassis Reinforcement Kits & Parts As much of an "Ultimate Driving Machine" it is, many BMW models unfortunately suffer from weak points in the chassis. Over the years we have uncovered many weak or failure-prone areas in the chassis and have developed our own reinforcing solutions for them. And we continue to be the leading experts on BMW chassis reinforcing. Failures can come from a number, or combination, of causes: improper maintenance, age and mileage, poor design, environmental factors, poor repair work, and over-stressing modifications. The longer you let your car go without repairing or reinforcing these areas, the closer it gets to crumbling apart. Our chassis reinforcement kits are designed to first identify potential weak points and then strengthen and reinforce the existing design.

Most of our kits are not labor intensive although welding is usually required. If you suspect your chassis may have structural problems we recommend taking it to a well-known bodyshop or restoration shop. (find out who your local BMW dealer uses - we sell many of our kits to dealer-authorized repair shops). Making the preventative fix simple and effective is better than a long and complicated repair after the failure. Our kits are not usually used for fixing existing damage (only your body shop can determine the correct course of action). But our kits have been proven under extreme conditions on racetracks around the world to prevent many of the costly - and dangerous - chassis problems.

Heavy Duty Rear Shock Mount Reinforcement Plate Set 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.

E30 M3 Front Sway Bar Reinforcement Kit 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.

Race Skids Front Cross Brace Reinforcement - E30 RWD

The E30 has been and still is one of best cars to take to the track. It has proven to hold its own even against newer models of vehicles and leave many in the dust! Unfortunately, due to its design, this chassis allows for a noticeable about of chassis flex, so much so, that it can directly affect the steering response and the driver's ability to effectively control the car. This could cause you to lose the edge when driving aggressively or on tracks that often twist and turn.

To counter this, Race Skids provides a heavy duty Cross Brace Reinforcement that assists with keeping body flex controlled, tightening up the suspension and giving the car a much tighter feel! Reducing body flex helps to keep everything properly aligned, ensuring the best steering control and response possible.

These work great for mildly driven street vehicles and are even better for vehicles that see a lot of track time. Reinforce your vehicle's sub-frame and frame to tie in the rest of your suspension upgrades and give you a major advantage!

This cross brace is powder coated to prevent rust and corrosion from eating away at the welds, keeping this brace as strong as possible for a long time to come. Installation hardware is include for a simple installation process.

Fits the following BMW's:
1984-1991 E30 BMW RWD Models

E30 Front Subframe Reinforcement Kit As E30s get older they develop cracks and bends in places that see a lot of stress. One of the most stressful areas is the front subframe, especially because of worn motor mounts. A sure sign that your subframe is not holding up is that paint will chip and peel from the stressed area. It's a good idea to reinforce your front subframe the next time you're doing any suspension work and a must when replacing motor mounts.

This kit installs on the underside of the motor mount gusset and reinforces the upper sheetmetal of the gusset as well as closing off and reinforcing the lower section. Requires welding. Kit includes 2 motor mount reinforcements, 2 subframe "ear" reinforcements, and instructions.

This item fits the following BMWs:

E30, Z3 Rear Sway Bar Lower Link Reinforcement Kit 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.

E30 Rear Sway Bar Reinforcement Kit

Save 20%

A suspension mount is designed to take the stress and force of a suspension. A modified suspension, however, puts more stress on that mount. Time is not kind to mounts either, especially when they're metal and have been exposed to the elements. In the E30 rear sway bar, the bushing mounts to a tab coming off the rear trunk floor. Unfortuntately, the tab is insufficiently reinforced from the factory. As the tab flexes it will stress and tear the mounting tab off the chassis. A car that is babied and not driven hard may not suffer from this failure. But most E30s are in enthusiast hands now and are driven aggressively. If you don't reinforce the rear swaybar bushing mount IT WILL fail - no doubt about it.

This kit includes two factory U-shaped brackets with extra gusset reinforcement, installation hardware, and instructions. Each reinforced bracket bolts to your car's trunk (drilling required). Any sway bar bushing designed to be used with the stock bushing brackets will work with our kit, making this compatible with many sway bar upgrade packages!
