034 Motorsport - 2-Piece 380mm Floating Front Brake Rotor Upgrade BMW F80 M2/M3/M4.

The 034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit for the BMW F8x M2/M3/M4 is a complete replacement 380mmx30mm brake rotor kit, designed to work flawlessly with the factory front calipers found on the BMW F8x M2/M3/M4. Weighing in at approximately 23.8lbs, each rotor reduces rotational weight by 0.2lbs on each corner over the factory 24.0lbs rotors. While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture heat, while utilizing 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

Weighing in at approximately 23.8lbs, each rotor reduces rotational weight by 0.2lbs on each corner over the factory 24.0lbs rotors. While reducing weight, the rotor retains proper thermal mass in the rings to adequately capture, and 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. The rotor utilizes 72 directionally curved vanes to forcefully flow cool air through the rotor to dissipate heat.

The face of the 034Motorsport 2-Piece Floating Front Brake Rotor Upgrade Kit utilizes J-Slot slots to clean the pad and surface of contaminants and allows hot pad outgassing, all while reducing overall braking noise compared to a traditional slotted rotor.

The 034Motorsport rotor and hat floating mount system 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.

looks nice, well made and styish.
This was a gift for a friend. It is well made, has a good modern style to it, comfortable to wear, she is taller, and it fits her well. Its a bit warm, so a fall kind of clothing option.

Perfect for casual wear and dressy style
Color: Dark Green, Size: Small
This sweater is soooo soft and the color is so rich. The fit of it is perfect, not too tight and not too baggy, just right and I used the size guide to pick my size. Just for reference, I am 5'3" and 130lbs, 38C bust. It's well made and washes great. I chose to hang dry mine as I typically don't put any of my sweaters in the dryer to dry, just to fluff them. I have this one in two colors, the green and the tan/beige and I would say they are both a true representative of the color shown.

Love the long sleeves!!!
Color: White, Size: Small
Love it! I'm 5' 11" tall and I purchased this according to reviews. Several people commented on the length of the sleeves. I have a hard time finding sleeves long enough if it's not " tall" sized. It was perfect for me. If this washes nice I'm going to consider purchasing more in other colors. I ordered the white and just love the long ribbed cuffs with the line of buttons. Very soft.

Great sweater for winters in the Midwest
Color: Black, Size: X-Large
Love this sweater! I went back and got another color! The fit is true to size and very comfy. The button detail on the sleeves just adds a little pizazz. The weight of the sweater is perfect for winters in the Midwest.
