BMW Suspension Parts

Looking to stiffen up your rear shock mount without going for a solid rear mount? The Polyurethane Rear Performance Strut Mount from IRP will give you the stiffer reinforcement without giving you the typical noise, vibration, and harshness that come with traditional performance strut mounts. The polyurethane also helps with preventing rear shock blowouts, a common problem for stock BMW rear mounts that are paired with stiffer than stock suspension. 

The bearing sleeve and poly bushing are built to work with all stock style shocks such as Bilstein and H&R coilover and suspension kits.

Fits the following BMW chassis:
E36 BMW All Submodels except for 318ti
E46 BMW All Submodels
E30 BMW All Submodels
E36 Z3 BMW All Submodels
E85/E86 Z4 BMW All Submodels

This kit is contains all new strut and shock mounts and hardware needed when installing a new shocks and struts or aftermarket suspension on your vehicle. 

Fits the following BMW's

E82/88 128i 135i

E90/92/93 325i 328i 330i 335i 335is 

**For vehicles with coilover front suspension**

When looking to dial in your steering geometry and alignment for reduced tire where and/or better track handling, the stock suspension is quite limited. To fix this, you can install Camber/Caster plates such as these plates from IRP. Camber/Caster plates allow for adjustment of the top position of the shock's mounting position. These slight adjustments have a huge impact on the stance of the of the wheel when driving straight down the road and when turning into a corner. With simple adjustments, you can increase the grip of the tires in hard turns, improve tread life, or even just make an alignment correction for a vehicle with a lowered ride height. 

The IRP Camber Caster plates are made of an aircraft grade aluminum body, for strength and low weight, with an adjustable mounting plate that utilizes a steel monoball mounting point. This makes the plate resistant to corrosion and prevents deformation even with the stiffest shocks and springs.

Features:

• Decreased understeer
• Decreases outside edge tire wear
• Aircraft Grade Aluminum Construction
• Steel Monoball and Mounting Sleeves

Fits the following BMWs:
1991-1999 E36 BMW

A strut tower brace adds additional reinforcement to the front strut towers, tying them together for extra rigidity. This makes the whole structure stronger with less chassis flex. Handling and steering feel are improved with better turn-in and input with no downsides. 

The IRP adjustable strut brace bar is a high quality brace that is constructed of 100% steel for guaranteed reinforcement and prevention of flex. The brace bar is painted black to ensure corrosion protection and to add to the looks of the engine bay.

Easily installed with basic hand tools.

Fits the following BMW chassis:
E46 BMW All Submodels

If E30 needs a little more pep in the corners, this is an excellent suspension package. H&R Sport springs and Bilstein Sport shocks for the E30 will lower the ride height for an aggressive stance and stiffer springs will improve handling and balance in the corners. This suspension is a favorite among our E30 fans because the car corners better without a punishing ride. Perfect for daily-driven E30s who want to carry more speed through the corners.

H&R Sport springs lower the ride height by 1.25" and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 40% stiffer than the stock original springs.

We use Bilstein Sport shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. These fit with the stock strut and shock mounts, making for an easy and clean install.
 

Parts list:

• 1 set - H&R Sport Springs (50406)
• 1 pair - Bilstein Front Sport strut inserts (P36-0335 / 34-003350)
• 1 pair - Bilstein Rear Sport Shocks (B36-2027 / 24-020275)

Fitment note: Front strut inserts fit the larger 51mm strut housings. These were standard for all 6-cylinder E30s, all M3, and 1989-1992 318i/is. Other models used a smaller strut housing which requires a different Bilstein insert.

This item fits the following BMWs:
1984-1992 E30 BMW 325e 325es 325i 325ic 325is

• rear sway bar bushing brackets, 33556780707
• bracket mounting screws, 07119907125
• rear sway bar links, 33556764428
• lower link mounting bolts, 07119903931
• upper link mounting nuts, 33326768884

These M3 rear guide rod arms are an upgrade for the non-M cars. The stock non-M arms are made from sheetmetal spot welded together at the ends. The arm tends to flex and bend under even moderate cornering loads. Factor in gripper tires and more torque and this arm is inadequate for stability and consistent handling. The M3 arms are one piece of aluminum offering greater strength and with a sealed monoball inner bushing that allows the arm to rotate (instead of twisting).

This package includes:

• Left M3 Guide Rod - 33322283547
• Right M3 Guide Rod - 33322283548

This suspension package for the E93 convertibles will lower the ride height for a better stance and give you better handling. The stock suspension can be very soft with a lot of bodyroll. If you want your 'vert to handle more like a sports car and less like a town car, this is the right suspension for you.

H&R Sport springs lower the ride height as much as 1.3" in front and 1.2" in the back and stiffens the spring rate. Both combine to lower the car's center of gravity and reduce the amount of bodyroll in corners. The springs are progressive rate so their initial stiffness is actually very compliant and it becomes stiffer as the spring is compressed. This is great for street cars that see bumps and potholes where suspension compliance is key. Overall, they are about 30% stiffer than the stock original springs. Lowering amount will be less if replacing the factory sport suspension.

We use Bilstein Sport shocks as the dampers and they feature Bilstein's patented and innovative valving system. With this system, small bumps and impacts are absorbed as they should be. But the shocks stiffen for cornering and other suspension motions. It's the best of both worlds as the shock self-adjusts based on suspension motion. Bilstein Sport shocks work with these shorter springs because the only change Bilstein makes is a slightly longer shock. These fit with the stock strut and shock mounts, making for an easy and clean install.
 

Parts list:

• 1 set - H&R Sport Springs (50490-5)
• 1 - Bilstein Left Front Sport strut (35-120407)
• 1 - Bilstein Right Front Sport strut (35-120414)
• 1 pair - Bilstein Rear Sport Shocks (BE5-C039 / 24-120395)
