034Motorsport 2-Piece Floating Rear Brake Rotor Upgrade Kit for G20 BMW M340i & A90/A91 Toyota SupraThe 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 callipers found on the G20 BMW M340i & A90 A91 Toyota Supra.

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 callipers 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 aluminium. 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.

Nice jewelry box
Color: White, Size: 2 Layer, Color: White, Size: 2 Layer
This is a very nice jewelry box. It has two drawers with lots of compartments and can hold a lot of jewelry. I love that it is easy to see inside the compartments and will make it so easy to organize my jewelry. It doesn’t take up much space and looks great on the dresser. I highly recommend this jewelry box!

Excellent organizer
Color: White, Size: 2 Layer
I wanted something to help me with the jewelry I keep in our safe and this works perfectly. I had kept items in their individual boxes, having to open each one to find what I sought. No more. I keep my more popular items in the top tray and I can see them through the glass. Next order items are in the lower drawer and easy to see many at once. The compact size lets it sit in the same form factor on the shelf in the safe. I’m very pleased with it.

“Stylish and Spacious Jewelry Box, but Quality Could Be Better”
Color: White, Size: 2 Layer
The Casegrace jewelry box looks elegant and feels durable with a nice weight to it. The interior is soft and well-organized, with plenty of compartments for rings, earrings, and other pieces. It’s great for keeping jewelry neatly arranged and easy to find. However, the top cover isn’t real glass — it’s more like plexiglass or plastic — and it doesn’t lift open, which was a bit disappointing. The outer material looks nice but feels like it could start to wear or peel over time. Overall, it’s still a stylish and functional jewelry box with good storage space and a clean look, but the build quality could be a little better for the price.

Top tier rotating jewelry box; soft and great quality
This has got to be the most functional jewelry box I’ve ever seen. It’s not very traditional in design and I love that about it. It stands vertically and rotates! Every side is designed differently and constructed to house multiple types of jewelry. I tried to snap a picture of each angle. I like that it has features to keep the jewelry organized too, like the necklaces or bracelets that can be hung on clips/rungs and placed neatly inside a pocket which kind of binds it into place and lowers the chances of it tangling. There’s even a mirror that you can look into when putting your jewelry on. It seems like the box favors rings and necklaces more-so than earrings (which I have most of) but you can get creative and place earrings in the pocket that’s under the mirror flap or inside the drawer. This is definitely worth its value—it does not disappoint! 5/5:)
