South Bend Clutch Stage 2 Daily Driver Clutch Kits

South Bend Clutch Stage 2 Daily Driver clutch kits are engineered for vehicles with high performance modifications. The heavy-duty pressure plate has an increased clamp load with little or no increase in pedal pressure to offer stock feel, while increasing strength and durability. The organic disc material has a high metal content that increases the co-efficient of friction by two times over a stock lining. This greatly increases rotational strength up to a 12,000 rpm burst point for high performance. South Bend Clutch Stage 2 Daily Driver clutch kits are recommended for daily performance, street, and moderate race vehicles. Select the kit designed for your application needs.

APR Suspension Control Upgrade Units

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
