Unplugged Performance Billet Rear Camber Arms V3 Have a lowered Tesla Model 3? Lowering your car introduces more negative camber in the rear, in most cases more than ideal. The stock rear camber is not adjustable, which is why you need the Unplugged Performance Billet Rear Camber Arm Set for your lowered Tesla Model 3. Developed with feedback from development and racing driver Randy Pobst combined with real-world use data, this latest version of Unplugged Performance Billet Rear Camber Arms is lighter and stronger than ever. Unplugged Performance spent the time to engineer the world’s best product, and the results are easy to see. A Must for Lowered Cars, Street or Race Track On a street car, having adjustable rear camber gives you improved tire longevity and better straight-line braking by allowing you to return to factory rear camber alignment settings on lowered cars.For a high-performance driver looking to maximize handling, having the ability to set the rear camber on your Model 3 lets you dial in your Tesla's handling. Silent Running and Low Vibration Both the Unplugged Performance Street and Track Day versions of their Billet Rear Camber Arm Set use a high-end German OEM sealed and self-lubricating spherical Teflon bearing. Prioritization on reduced noise and vibration utilizing an OEM sealed bearing sourced from Mercedes-Benz. This design offers reduced deflection, meaning that when driving hard, the alignment is more consistent mid-corner, which improves handling feel and predictability. Far superior to rubber or urethane bushings. This results in quiet use, reduced vibration, low maintenance and long life. This is directly comparable in feel, and quiet usage to other sealed bearing designs on the market. Preset Every Time Every Unplugged Performance camber arm is assembled in a jig that's preset to match the factory Tesla rear camber arm length. This simplifies installation by giving you a factory camber baseline with every set. Billet Aluminum for Superior Strength Crafted from high-grade billet aluminum, the Unplugged Performance Adjustable Rear Camber Arms are not only lightweight but also boast an unparalleled strength-to-weight ratio. This ensures they withstand the rigors of aggressive driving and competition use. Meticulous attention to design detail guarantees a perfect fit for your Tesla Model 3, seamlessly integrating with the vehicle's suspension system. CNC machined from billets of aircraft-grade 6061-T6 aluminum, with a rugged and corrosion-resistant Cerakote clear finish to showcase the billet construction. Adjustability is at the heart of these camber arms, providing you with the flexibility to fine-tune your vehicle's rear alignment for optimal tire contact patch under heavy cornering loads. This precision adjustment capability allows for enhanced grip and stability, enabling you to push your Model 3 to its limits while maintaining control. Whether dialing in your suspension for a specific track or adjusting for tire wear, these camber arms offer the adaptability you need to stay ahead of the competition. Installation is straightforward, with clear instructions that allow for a hassle-free setup, ensuring you spend less time in the garage and more time on the road or at the track. Sold/priced in pairs.

AiM Sports LCU-One Lambda Controller Kit LCU-One CAN is the lambda controller unit designed to work exclusively with Bosch LSU 4.9 wideband probes, which are the quickest and most accurate way to analyse exhaust gases and provide a real time parameter related to engine carburetion. Lambda probes can be applied to two- and four-strokes engines, gasoline, diesel, methane or alcohol based fuels. LCU-One CAN communicates with your AiM MXL, MXL2, or MXG/MXS dash; EVO3/EVO4/EVO5 data logger; SoloDL lap timer; or MyChron4/MyChron5 kart dash via CAN. This provides lambda value, air/fuel ratio, probe temperature and diagnostics parameters. An external 12 volt battery is required to supply power to the whole AiM system, and any other AiM expansions. LCU-One CAN is the only AiM Lambda Controller compatible with MyChron5.

Schroth QuickFit Pro Four-Point Harness For the first time, a four-point harness has been designed for use with a HANS device and your car's stock seats1. Perfect for HPDE, Track Day, and Driving School cars, the Schroth QuickFit Pro four-point harness provides your customers a safer, more authentic driving experience by driving with a HANS device. With this harness, you don't have to spend thousands of dollars on a roll bar, new seats, and six-point harnesses to run safely on track! Coupled with a vehicle’s existing safety systems, the Schroth QuickFit Pro is designed to maximize effectiveness of your HANS device. Traditional four-point harnesses are sewn to lap belts, and don’t join at the center cam lock. This creates a six- to eight-inch gap. The Schroth QuickFit Pro answers this problem by allowing each shoulder belt to angle towards the cam lock, integrating with the HANS device. The Schroth QuickFit Pro works in conjunction with your car’s seat belt pre-tensioner and airbag for additional peace of mind. The QuickFit Pro clicks into the car’s female seat belt receptacle, notifying the car’s airbag computer that the seat is in use and the driver is restrained. The pre-tensioner is also activated. This device ignites a pyrotechnic charge if an accident happens, tightening the lap belt and holding your driver in snugly. 1 Important: the Schroth QuickFit Pro Four-Point Harness is meant to be used only with stock front seats that have passed a seat-back strength test by the auto manufacturer.

Pagid Racing RSL 29 (Yellow) The Pagid RSL 29 (Yellow) is the world-leading endurance brake pad used by most of the winning teams in motorsports.  This racing compound combines the outstanding wear rate of the RS 19 with a slightly higher coefficient of friction and initial bite. Based on the more aggressive Pagid RS 14 (Black), a slight reduction of the friction value improves the modulation (control) of RSL 29. Nevertheless, RSL 29's friction value is high enough for cars without power-assisted brake system and ensures comfortable low effort on the brake pedal. Constant temperatures up to 600°C (1,100°F) are possible. This combination of friction value, fade stability and low wear on pads and rotors is unmatched. Pagid RSL 29 provides very high levels of performance and response at all temperatures; not much heat is needed to bring the pad up to its optimum performance level. It's a favorite with endurance racers, having won many classes at major endurance events at Le Mans, Daytona, Spa, Nurburgring, etc. Exceptional pad life and very low rotor wear have made it possible to run 24 hours without a change of pads or rotors! Although designed primarily for endurance racing, RSL 29's consistent levels of performance and user friendliness make it popular for sprint- and short distance races as well. RSL 29 has also found favor in the growing track day market due to the level of control, good cold performance, long life, and low rotor wear.
