Dinan Rear Diffusers

Dramatic exits come standard with Dinan's carbon fiber rear diffuser upgrades. The multi-piece diffusers spotlight the rear of the car and create a new "floor" that visually appears to make your vehicle lower and more aggressive. Despite the diffusers encompassing the exhaust exits, great care was taken to ensure enough room was supplied to accommodate large-tip exhausts, like Dinan's own. Additionally, the diffusers add wraparounds to each of the rear quarters, establishing a harmonious and uniform visual continuation with Dinan's front lip and side skirts (not included) for a perfectly matched cosmetic solution. Dinan rear diffusers feature 2x2 gloss twill carbon fiber manufactured to be impact-resistant, durable, and strong. They are clearcoated for maximum UV protection and fade resistance, and include 3M double sided tape and mounting screws for easy installation with a clean fit and finish.

SPL Suspension Titanium Series Control Arms

SPL Suspension Titanium Series control arms allow for an increased range of rear camber adjustment, necessary for lowered cars and performance alignments. This provides more stability and predictability to the rear suspension for tighter handling. Using FEA (Finite Element Analysis), the CNC-milled 6061-T6 billet aluminum arms are designed to exceed factory strength and durability. The exclusive Double Adjuster is comprised of electroless nickel plated 4130 chromoly, along with 6061-T6 aluminum rotating clamps to reduce weight and prohibit corrosion, while offering quick and easy adjustment. Blue nodized titanium hardware shaves even more unsprung weight from the arms, without compromising strength. FK spherical bearings and rod ends are manufactured in Connecticut and utilize a PTFE liner to provide quiet operation, lower friction, smooth articulation, and eliminate bushing deflection under load. The liner is also self-lubricating and self-cleaning for robust reliability for street and track use. The PTFE liner is chemically bonded to the inner diameter of the race and offers a very high load-carrying capacity that has greatly increased dynamic wear characteristics. The operating temperature of the liner ranges from -65 to 325 degrees F. Order the pair designed to fit your vehicle.

South Bend Clutch Stage 3 Daily Driver Clutch Kits

South Bend Clutch Stage 3 Daily Driver clutch kits are recommended for single mass flywheel (SMF), when original design is dual mass flywheel (DMF). These clutch packages are designed for high-horsepower vehicles desiring a start performance similar to OE. The pressure plate is race engineered (SS) and SFI-approved with significant load increase over stage 1 and 2 pressure plates (+600-800 lbs.). Expect a pedal effort increase of 20 to 25 percent. Discs are assembled with heat-treated wear-resistant hubs, as well as drive plates and springs for high-load transfer and dependable operation. The sprung centers on the disc, in conjunction with the marcel fin between the linings, create a dual dampening effect that simulates OE start performance. A performance organic friction material with a high metal content increases torque and rpm capability—and maintains low operating temperatures, which reduce wear and glazing. South Bend Clutch Stage 3 Daily Driver clutch kits are the perfect match for your high performance street machine and occasional track use. Order the kit recommended for your application.

LuK Clutch DMF Flywheels

The downsizing of modern passenger car engines enables reduced fuel consumption and CO2 emissions, but can also increase rotational irregularities and natural vibrations. Torsional vibrations transmitted to other components in the drivetrain diminishes comfort and may even lead to component damage, therefore effective vibration damping is essential. LuK dual mass flywheels (DMF) reliably dampen torsional vibrations in the powertrain and ensure high gearshift and driving comfort in all speed ranges. Unlike a conventional flywheel, DMFs consists of two masses which are mounted to rotate against each other. A damping system in the form of arc springs is integrated to almost completely absorb the torsional vibrations of the engine. Precisely matched to the respective vehicle, each LuK DMF enables low-speed driving and ensures lower fuel consumption, as well as reduced emissions. Order the proper size for your vehicle.

ST Suspensions Adjustable Lowering Springs

ST Suspensions adjustable lowering springs deliver improved looks and more driving dynamics in OEM quality. The kits are a great alternative to conventional springs. You don't have to be satisfied with a fixed lowering, as you can adjust the height with the ST height adjuster even after the kit has been installed. Not only does your vehicle get a more dynamic look, but the steering behavior and response of the standard dampers also becomes more agile. All driver assistance systems and comfort features of an adaptive series suspension remain with these vehicle-specific developed spring setups. Order the springs recommended for your suspension. * No more 30-30 or 40-40! With conventional lowering springs, you have to decide on the lowering from the beginning—but not with the ST height adjustable spring kits. Depending on the vehicle-specific application, you can change the lowering within the adjustment range with the threaded spring perch when the springs are already installed. For example, the ST height-adjustable spring kit for an Audi S5 allows you to lower the car in the range of 5-35mm. You won't have any difficulties adjusting the lowering when changing your wheel/tire combination. * OEM Quality High-quality springs made of chrome-silicon steel are at the core of ST coilover spring kits. Their spring rates are adjusted to the respective standard suspension dampers and wheel loads of your vehicle. They will perfectly harmonize with the different damper characteristics of your adaptive series suspension. With their high-quality (surface) finish, as well as the ST height adjuster, the spring kits delivery content always includes the vehicle-specific bump stops with dust protection system to guard your standard suspension.
