The 034Motorsport 345mmx24mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the G20 BMW M340i & A90/A91 Toyota Supra is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the G20 BMW M340i & A90/A91 Toyota Supra. This is a true high-performance and racing-quality rotor that won’t let you down when you need hard braking the most! Weighing in at approximately 16.9 lbs, our lightweight design retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 enhanced directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

034Motorsport 2-Piece Rotors have been thoroughly tested in high-intensity motorsport events, proven to significantly improve braking and thermal headroom and for extreme performance street and track driving, making them the perfect replacement rotor for your G20 BMW M340i or A90/A91 Toyota Supra.

NVH Levels: NONE - LOW

NVH is the measurement of how much noise, vibration, & harshness gets transmitted into the cabin of your vehicle. The 034Motorsport 2-Piece Brake Rotors transfer none to low amounts of noise to the cabin based on user feedback. This NVH is relative to the brake pad installed with the brake rotor. Different brake pads will have different resonances when passing over a rotor with slots, which can sometimes make a slight whirring noise. The sounds from these rotors are the direct result of the performance improvements they make to the braking. The J-slots release gas from under the brake pad, and the high-density directional aero veining in the rotors move substantial air, all resulting in more sounds of air moving. The installation of other suspension components can also affect the NVH transferred. NVH is subjective, so some users may find NVH to be increased or decreased from our rating. If you are experiencing higher than quoted NVH with this product, please email [email protected] for further assistance.

Product Description:

The 034Motorsport 345mmx24mm 2-Piece Floating Rear Brake Rotor Upgrade Kit for the G20 BMW M340i & A90/A91 Toyota Supra is a complete replacement brake rotor kit, designed to work flawlessly with the factory rear calipers found on the G20 BMW M340i & A90/A91 Toyota Supra.

Weighing in at approximately 16.9 lbs, our lightweight design retains proper thermal mass in the rings to adequately capture heat, while utilizing 36 enhanced directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

The central hat portion of the 034Motorsport rotor is made of 6061-T6 aircraft specification aluminum. The disc is constructed out of a proprietary metal alloy that can withstand immense braking temperatures while holding form allowing hard street use and long days at the track, allowing you to drive versus working on the car. These rotors improve thermal capacity by utilizing 36 directionally curved cooling vanes to forcefully flow cool air through the rotor and are profiled specifically to improve heat dissipation compared to the OE rotor vane design.

The face of the rotor utilizes J-Slot slots which increase braking surface area over drilled rotors as well as clean the pad and surface of contaminants and allow hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor. This J-Slot design also improves upon the OEM drilled rotors, as drilled rotors are prone to cracking after repeated abuse.

With its true 2-Piece design, the rotor and hat have a floating mount system that utilizes high-strength alloy steel bobbins. The pins take the load from braking actions while maintaining the axial and radial float between the hat and disc, allowing for safe expansion and contraction from heat. This 2-Piece design also makes repair costs in the future significantly less overtime, as only the rotor rings would need to be replaced.

034Motorsport 2-Piece Rotors have been thoroughly tested in high-intensity motorsport events, proven to significantly improve braking and thermal headroom and for extreme performance street and track driving, making them the perfect replacement rotor for your G20 BMW M340i or A90/A91 Toyota Supra.

Great style and comfort
This is a fantastic sweatshirt! Made from a high quality fabric this shirt doesn't even feel like what you think of when you think "sweatshirt". It has a sophisticated design pattern and a great style perfect for golf or even to wear to the office in a casual tech company. My husband has done so and got many compliments and requests to tell him where he got it! It is true to size, with a cut that fits a variety of body sizes perfectly. It is very flattering, comfortable, and soft. It just looks great. It washes easily, stains do not set and neither do wrinkles. I intend to buy more of these in other colors.

Excellent Midlayer for Golf
Color: Light Brown Heather, Size: X-Large
My dad has been wearing this M MAELREG hoodie for about a week now, specifically during my early morning golf rounds where the temperature sits in the low 50s. The fit is true to size with an "athletic" cut, meaning it’s tapered enough to look sharp but has enough stretch and light enough to allow for a full shoulder turn during a golf swing. The cost is also a lot lower than some of the tech golf shirts out there. Overall this is a great shirt for golfing with an expensive look.
