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.

I recommend using the KONG Extreme Dog Toy
Style: Sport, Size: Large
Helpful for throwing as much as my dog wants to fetch. I actually had to get a cortisone injection in my shoulder a few months after getting my dog - never had a dog with this much energy before! The Chuckit really helps. Downside: The ball that comes with it is larger than a tennis ball, so may be too much for smaller doge. I can't imagine my sister-in-law's french bulldog carrying it! Also, in our house it gets destroyed within minutes, as my dog is a strong chewer. For this situation, I recommend using the KONG Extreme Dog Toy, Black, size Large. This is shaped sort of like a snowman, which means it bounces unpredictably at times. My dog eventually chews the "head" off of this toy, but the remaining 2/3 still fits in the Chuckit (and is actually easier to throw with the "head" missing!). One caveat: the KONG is significantly heavier than the ball included with the Chuckit, so be aware of that... Also, we ordered our first Chickit in October 2015, then needed to replace it in May of 2017, as it broke. I think the plastic became brittle over that time, as we left it out in the sun & rain in Florida. Since it is cheap to replace, that's not a big deal. (We ordered three Kong toys over that same period of time!) To summarize, it's a very helpful tool to get the ball further, faster, with less strain, than without it. Knowing there are alternatives to the included ball for heavy chewers makes it worthwhile.

Great Ball Launcher!
Style: Sport, Size: Large
Our dogs love this ball launcher! I can throw the ball long distances without any arm strain. The balls wear out, and as described by others, tennis balls don’t fit. Buy extra balls if this is of concern. We bought a few of the “Chuck It” rubber 3” balls and they have worked well for our dogs. It’s a great value and fun for the dogs.

Chuckit!! Just Chuck it!!
Style: Sport, Size: Large
Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!

Perfect toy for an active dog!
Color: Large size (7.9")
My dog absolutely loves this ball with handles! It’s quickly become one of his favorite toys, and he gets excited every time we bring it out to play. The vibrant colors are a huge plus—they make it super easy to spot in the grass, which saves a lot of time during outdoor play sessions. The handles are great for interactive play too, especially for tugging and tossing. I’m really impressed with how well it’s holding up. Even with constant pulling, tugging, and rough use, it’s remained durable and hasn’t shown any signs of wearing out. Overall, I’m very happy with this purchase—and if my dog could write reviews, it would definitely get his paw stamp of approval! 🐾
