The APR Suspension Control Unit (SCU) Upgrade directly replaces your factory suspension controller with a new unit that enables advanced control over your vehicle's factory electronic shocks. The factory controller only operates in a "soft" or "stiff" state with no behavior in-between, despite the incredible capability of the factory electronic shocks. This controller has advanced programming that takes various inputs to provide fine-tuned control over the shocks in real time. The controller still retains factory comfort and sport functionally, and it doesn't compromise ride quality for performance. However, both modes rapidly increase performance depending on various inputs—such as acceleration, brake pressure, G-forces, steering angle, speed, and damper shaft velocity. The experience is absolutely transformative. For the casual driver, the vehicle is more comfortable and rides better than stock. Uncomfortable bouncing and stiffness are reduced, and the car settles faster to provide increased stability. This is accomplished by using the full operating range of the electronic shocks to provide a pleasant experience when you're driving normally. But once you begin pushing the vehicle, the controller quickly adapts to provide performance you never knew was possible from the factory shocks. Even on a straight-line launch, the system will help control weight transfer so you can improve your 60 ft. times for better acceleration and better times in the quarter-mile. On a twisty back road, or on a proper track, the controller adjusts each shock individually to provide the grip you need to cut faster lap times with more confidence as the chassis is more balanced. It improves weight transfer on corner turns by allowing a smoother transition, all without the shocks loading the tires, while also reducing overall body roll. Simply put, your vehicle will ride and perform better in every scenario and stays true to our mantra of performance without compromise! Order the Suspension Control Upgrade Unit recommended for your vehicle. Product features: * Direct plug-and-play upgrade * Provides full dynamic control over the electronic shocks in real-time * Optimized ride quality and comfort during normal daily driving * Optimized performance, handling, and cornering during spirited driving * Optimized launch control, traction, grip, and weight transfer * Reduces 60 ft. times for improved acceleration * More confident driving experience * Advanced signal processing provides real-time changes lightning fast speeds * Reacts in real-time to driving style to provide comfort or performance * Retains various factory levels of switchable performance; example: "Comfort" vs "Sport" * Fully 3D-mapped to the capabilities of your factory electronic shocks * Compatible with aftermarket springs, stabilizer bars, and other upgrades * Unit is unlocked and fully upgradable in the future * Unit is completely reversible and removable without a trace

Steeda's S550 Mustang adjustable front sway bar end links make a great upgrade for the stock end links—as well as the perfect dual-purpose street/open track asset. For street applications, these end links are as quiet as the factory originals. They will not add NVH (noise, vibration, harshness) like rod end units. The purpose of sway bar end links is to connect the sway bars to the suspension—at the front to the strut, at the rear to the control arms. Due to their location, the end links play a key role in relation to how your suspension works (especially the anti-roll bars). As the suspension compresses and rebounds, the end links move with it. With each movement of the control arms or the struts, the end links move and control the sway bar. If you have a lowered car, you have inadvertently changed the position of the sway bar, which changes the angle of the arms. These Steeda S550 adjustable end links enable you to restore the factory angle and the effectiveness of the sway bar.

APR lowering bump stops improve handling and ride quality—and are designed for use on lowered vehicles, such as those with APR Roll-Control lowering springs. Bump stops are a critical handling and ride-quality component of your suspension system, but they're often completely overlooked. Most setups are either running the factory bump stops, which are too tall (causing constant engagement during normal driving); cut bump stops, which remove the progressive dampening; or they've removed them altogether. All of these scenarios hurt handling and make the ride harsh. APR bump stops are designed using a balance of durometer (hardness) and length to tune comfort and handling under normal and aggressive driving scenarios. The balance takes the following into account: * Length: A longer bump stop, like the factory units, will have more volume to absorb a harsh impact. But during normal driving on a lowered vehicle, they will constantly contact, which impacts both handling and comfort. The quick engagement can disrupt handling and cause driver discomfort. APR shortened the bump stop to ensure that they work on a lowered vehicle, but kept them tall enough so they have enough volume to absorb a hard hit. * Durometer (hardness): An overly soft bump stop is comfortable but can't absorb enough energy to protect from damage. Likewise, an overly stiff bump stop will impact ride quality, and impact handling negatively. Testing various setups, APR found a balance by increasing stiffness to provide better handling without going overly stiff as to impact comfort. The bump stops also have a progressive rate to them with a soft "nose." This allows the bump stop to gently engage so as to not disrupt handling. It's also less noticeable to the driver, aiding in the comfort of the driving experience. * Specifications: -- Material: PUR -- Front / Rear durometer: 75A (~50A OEM) / 65A (~55A OEM) -- Front / Rear I.D.: 19mm / 17mm -- Front / Rear O.D.: 56mm / 59mm -- Front / Rear length: 40mm (56mm OEM) / 80mm (110mm OEM) * Note: The OEM MK7 GTI, Jetta GLI, and Golf R, MK8 GTI, MK8 Golf R, and others all share the same bump stop length and durometers. Some have an extra ring to make them feel stiffer. * Bump stop features: -- Designed for lowered vehicles -- Improve handling and comfort -- Shorter than stock, enabling vehicle lowering without being overly short -- Increased durometer than stock without being overly harsh -- Progressive spring rate with a soft "nose" to provide a gentle engagement -- Perfect match to APR Roll-Control lowering springs -- OEM external dimensions for factory fit compatibility -- OEM quality black PUR (Polyurethane) material for durability and longevity -- Includes all 4 bump stops: 2 front and 2 rear
