BMW Suspension Parts

MINI F56 Dinan Coilover System offers the MINI driver unparalleled versatility for achieving optimal performance in any situation. This adjustable coil-over suspension system allows for customization, enabling configurations that range from factory-like comfort to maximum performance, or a combination of both. Whether used for daily driving or track performance, the improved suspension provides exceptional traction, enhancing confidence at higher speeds.

The Dinan Coil-Over System for F55/F56/F57 MINI models is engineered to deliver outstanding handling performance. It includes performance-tuned linear rate springs, adjustable front strut assemblies, and rear shocks with integrated bumpstops for reliable behavior. Key benefits include:

• Adjustable Ride Height: Up to 1.7" lower in front and 1.1" in the rear, with a recommended 0.75" (20mm) drop to maintain ride quality.
• Enhanced Handling: 93% stiffer front springs (336 lbs/in vs. 174 lbs/in) and 58% stiffer rear springs (336 lbs/in vs. 213 lbs/in) improve grip and reduce body roll.
• Customizable Comfort: 32 levels of rebound damping adjustment and threaded collars for precise height adjustments.
• Durable Construction: Corrosion-resistant materials and finishes for long-lasting performance.
• Improved Performance: Substantial reduction in body roll and increased handling capabilities.

Note: Not compatible with cars equipped with EDC/DDC.

Dinan Adjustable Spring Sets feature stiffer springs and an innovative perch system that allows the ride height to be fine-tuned even with stock shocks. Dinan Performance springs are slightly lower but stiffer for better handling and less body roll yet still remain comfortable for normal use. They have carefully engineered the springs to work within the rates of the stock shocks, providing unmatched handling, looks, and ride quality. Adjustable spring perches give you the ability to keep your stock shocks (even EDC) but lower the ride height and set the perfect stance. This is hugely beneficial when using larger wheels and tires where a standard spring drop will not give you the look you desire. Dinan coil over springs include a threaded collar that fits over the stock strut body in the front and an adjustable perch in the rear. New progressive bump stops are also included to maintain the proper shock travel. This kit is great for fine tuning your ride height while retaining the factory EDC system.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 3 points towards your Dinan badge.

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

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 Dinan strut tower brace is a very high quality aluminum brace with precision machined ends that match the contours of the strut tower. Other braces simply sit on top which reduces their effectiveness. This is definitely one of the stronger strut brace designs on the market. The center bar is polished aluminum with carbon fiber inlays - an unmistakable sign of precise engineering when you open the hood.

**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:

For the driver that demands the best out of their vehicle. The Dinan Adjustable Coil-Over Suspension was bred in the race lab but refined on the street for maximum versatility. No matter the environment, the traction that is awarded to the vehicle from the improved suspension will inspire newfound confidence when running at higher speeds. From the substantial reduction in body roll as well as reduction of dive under braking and squat under acceleration, Dinan guarantees you superior handling, performance, and comfort.

Dinan's design retains the superb factory electronic shocks but swaps the springs to a more aggressive, performance enhancing formula and implements threaded collars that allow the user to change the ride height themselves. While shorter, stiffer springs are commonplace in aftermarket suspensions and are a key element in reduction of body roll it is not a one size fits all approach. In the case of the G87 M2 where the vehicle has a penchant for oversteer, stiffening the rear springs would exacerbate the problem of the rear losing traction before the front when the platform is pushed to the limit. Dinan instead has opted to soften the rear spring rate as well as switch from the factory progressive rate rear to a dual rate spring setup. The combination increases predictability and compliancy, and in turn, provides better rear grip/road holding for a vehicle that needs both. The result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allow the car to be lowered up to 1-1/8" in the front and over 2" inches in the rear. However, to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 3/4" in front and rear is advised. For suspension connoisseurs, or those that are just simply very particular, suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops --- something no respectable race car is without.

Contrary to the market norm, the Dinan G87 M2 kit is not a direct carryover from the G8x M3/M4 but a package independently developed to eke the most out of the M2 and the nuances that differ it from its larger siblings. The rear spring rates in particular on the smaller coupe are far more aggressive than those on the M3/M4 from the factory. This produces a stiffer, more uncomfortable ride than most are fond of beyond the racetrack. While utilizing the same rear springs as the Dinan M3/M4 kit is possible the rates would be substantially softer resulting in reduced stability in cornering and an increase in body roll. Instead, Dinan M2 rear springs are 13% softer than factory but still 10% stiffer than what the M3/M4 kit would offer so a more compliant and comfortable ride can be achieved while also retaining its sporty character and abilities.

NOTE: Due to the extensive lowering possible and the increased suspension travel, the installer must carefully evaluate tire clearance under all situations. Safety will be compromised if all precautions are not taken. Dinan is not responsible for any property damage or injury.

Features:

• Up to 1-1/8" of lowering in front and over 2" of lowering in back are possible depending on tire clearance but with diminished ride quality
• Dinan recommends a 3/4" drop in front and rear to maintain a civilized ride
• Up to 1" of lift in front and over 2" in back over stock are also possible
• Threaded collars allow easy and precise front & rear vehicle height adjustments
• Spring rates are 29% stiffer in front and 13% softer in the rear for increased predictability and compliancy
• Substantial reduction in body roll
• Dinan-spec progressive bump stops improve ride quality at lowered ride heights
• Included suspension packers allow adjustment of bump-stop clearance to fine-tune handling and comfort
• Components are machined from 6061-T6 aluminum and black anodized for a sporty appearance as well as corrosion protection
• Stock upper spring mounts are utilized as well as spring isolators for quiet operation

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.
