Why a strut nut socket? To secure shocks and struts to their mounts, the retaining nut must be torqued to its proper specification using a torque wrench. Strut nut sockets allow for the use of a 21mm wrench to hold the damper shaft allowing you to achieve proper torque. An improper torque value may result in premature mount failure - or worse.

An underrated component of a proper driver's suspension the monoball kit (tension strut ball joint kit in today's terminology), is a remnant of an era when road feel was something desirable and sought after. Drivers wanted the visceral feel of being connected to the road as the road-racing heritage of BMW M demanded. Dinan embraced this and over the years mastered its craft into a kit that not only satisfied the desire for proper road feel but also made it livable for everyday driving. While stock suspension properties may have swayed from its golden era lineage to more mainstream ideals, Dinan is here to correct those mistakes for those that want a more M-passioned BMW experience. The Dinan Tension Strut Ball Joint Kit provides responsiveness you can feel by replacing the rubber bushings in the thrust arms with precision ball joints and machined aluminum housings. Improves responsiveness by eliminating the deflection inherent in the stock rubber bushings while also reducing brake shimmy. The quietest bearings on the market are virtually noise-free so you can live with them every day. They are also sealed using a rubber boot to keep out dirt and road grime stopping them from wearing out prematurely. Features: Improved steering responsiveness Reduces brake shimmy Nylon-lined bearings for quiet operation Machined aluminum housings Sealed bearings Compatible with both RWD and xDrive models

The Dinan G8x Strut Tower Brace provides additional rigidity and sharper handling to the chassis by reducing flex under hard cornering conditions. With more control, spirited driving becomes easier and infinitely more enjoyable. The lightweight brace is designed with maximum function in mind and includes linking structural elements that completely change the OEM 2-piece strut bar set into one blended system that offers additional strengthening against flex. Not one to take a back seat to functionality, aesthetics are also elevated beyond simple steel bars into striking carbon fiber (matte or gloss) with accents that tie in effortlessly into the highly geometric and angular factory engine bay for an OEM+ feel. The imposing carbon fiber brace can be installed in a matter of minutes and used in conjunction with either the stock or Dinan intake systems. While the brace was designed to specifically tie into the latter for a harmoniously balanced and unified appearance the brace can also stand on its own and elicit nearly as equally an impressive visual. Features: Improved chassis rigidity Decreased flex during cornering Lightweight: 5.6 lbs lighter than stock (Dinan CF: 2.8 lbs vs OEM Steel: 8.4 lbs) 2x2 twill carbon fiber with inset aluminum mounting points for increased strength and improved visual appeal Multiple finish options: Available in Gloss or Matte Twill Carbon (Matte Twill shown) Designed to mesh seamlessly with the Dinan cold air intake creating an aesthetically unified engine bay Bolt-on installation using factory mounting hardware

When dismantling a suspension strut sometimes the securing nut can be difficult to access and the central strut itself needs to be held still while the nut is undone. This new Shock Absorber Tool Kit is designed to overcome these problems and make the job quick and easy.

The go-through design of the sockets and ratchet design allows the strut lock extensions to go right through the middle of the ratchet and socket. Five different strut lock extensions are included, to fit a variety of applications. Seven go-through deep sockets (16, 17, 18, 19, 21, 22 and 24mm) are included, plus a sliding T-bar.

Once the spring is compressed and the top plate is free, simply choose the correct strut lock extension and socket. Then fit the socket and the ratchet handle, and fit the strut lock straight through. The central strut is held steady, and the securing nut is quickly removed.

Specifically designed for repairing and replacing shock absorbers and struts
Contents: 7 - Go Thru' deep sockets: 16/17/18/19/21/22/24mm
3 x 1/2"D Hex bits: 6mm/7mm/8mm,
1 x sliding T-bar 1/2"D,
2 x slot bit sockets 5 x 8mm, 6 x 8mm x 1/2"D

If you plan to upgrade your sway bar, we highly recommend complementing this purchase with the new Turner Performance Front Sway Bar End Links! While great for a daily driver, the stock BMW end links (31308091445 & 31308091446) aren't as strong as we'd desire them to be to stand up to demanding track use and abuse. These upgraded Adjustable End Links feature massive Teflon-lined FK 1/2" bearings to provide the highest load capacity for use with stiffer aftermarket sway bars. Heat-treated Chromoly High Misalignment Studs connect to the sway bar and offer extreme articulation capability (65 degrees) to prevent the end links from binding when used with different adjustment holes on aftermarket sway bars. Thanks to their adjustable design, these allow you to eliminate preload on the sway bars. Preload can result from uneven settling of springs or uneven suspension heights from corner weighting/leveling. Blue Anodized 6061-T6 Aluminum Turnbuckles work in conjunction with the left and right-hand threaded rod ends for simple and precise adjustment. NOTE: These end links are designed to work with vehicles that are at the stock ride height or slightly lowered (less than 1 inch).

The MMR Performance Lowering Spring set for BMW G82 M4 delivers the perfect blend of improved dynamics and enhanced looks, yet without sacrificing ride quality. The 35 front / 15mm rear drop in ride height brings the G82 to life making it feel lighter, more direct and with significantly sharper turn-in. The drop in ride-height makes a huge difference to the handling characteristics: by lowering the G82 M4's centre of gravity, it reduces body roll for better dynamics, whilst maintaining the ride quality and comfort of your car. Thanks to the carefully selected progressive spring rates the ride-quality remains unaffected and is actually nicer to drive at slower speeds. But push-on through the corners and the G80 chassis really comes to life, making it feel lighter, more direct and with significantly sharper turn-in. Meanwhile, the car's appearance is transformed. Our development has resulted in the springs providing a drop at the front of 35mm whilst the rear sits lower by 15mm. By getting rid of those nasty wheel arch gaps, it'll look just how it should have come from the factory! Go lower or stiffer than these MMR Springs and your car will bounce and crash as the dampers are mismatched to spring rate, and the springs themselves run out of travel. Finished in MMR Metallic Grey, the Sport Springs are developed to be fully compatible with cars fitted with either static or Adaptive M adaptive dampers. A must-fit for any G82 or G83 M4! FEATURES Carefully optimized spring rates for improved driving dynamics Designed to be compatible with Adaptive M and static factory dampers Lowers vehicle by 35mm front | 15mm rear Powder coated in MMR Metallic Gunmetal Grey for a durable finish

As your vehicle ages, rubber components begin to break down, allowing excess movement in the components that require a firm mounting point the most. The camber link allows fine adjustment of the rear camber. When the camber link bushings fail, the rear camber adjustment is compromised. The result is a loose feeling in the rear end, excessive tire wear, and a sacrifice in handling.

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 all approach. In the case of the G8x M3/M4 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 allows the car to be lowered up to 1-1/8" in the front and 2-1/4" inches the rear. However, to retain the ride quality synonymous with Dinan suspension kits the recommended drop of 3/4" (M4) or 7/8" (M3) in front and 3/4" in the 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. 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" of lowering in front and 2-1/4" of lowering in back are possible depending on tire clearance but with diminished ride quality Dinan recommends a 3/4" (M4) to 7/8" (M3) drop in front and a 3/4" drop in the rear to maintain a civilized ride Up to 1/2" of lift in front and 1-1/4" in back over stock is also possible Threaded collars allow easy and precise front & rear vehicle height adjustments Spring rates are 15% stiffer in front and 10% softer in the rear for increased predictability and compliance 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 Installation Instructions: https://documents.dinancars.com/d190-8210.pdf

Going beyond its Foundation counterpart, the Dinan Experience packages address not only the engine but also the chassis for a complete solution in the form of a wholly tuned Dinan vehicle. While adding power modifiers is often the go-to path when beginning the modification journey, it does not fully consider what makes the car infinitely more enjoyable in scenarios outside of WOT pulls. With the addition of suspension upgrades integrated alongside the power adders, the vehicle is transformed into something more than just the sum of its parts. It's a comprehensive answer to delivering additional technical capabilities in the form of increased engine performance and better handling along with improvements to aesthetics (looks and sound) in a package designed with reliability and safety in mind. This union of power and handling modifications results in a true OEM+ experience - the Dinan Experience.
