This is a Mini 4WD front AT (Angle Tilt) sloped damper bumper. The roller mounting section has been stepped down, allowing the rollers to be mounted 3mm lower than usual. The advantage of this is that the rollers hit the course at a lower position, stabilizing the car body, and making contact with the walls earlier in corners after jumps, reducing the chance of going off-course. Angled brake processing is also available for an additional 1500 yen. The sloped damper will be made using SKWorks' jig. It will be made to order, so please let me know which chassis you will be using so I can make it to fit. It will take about two weeks to ship. The carbon fiber parts used may differ from the photos depending on stock availability. We will ship after confirming smooth movement, but the movement may become stiff if disassembled and reassembled, so please apply grease and make adjustments yourself.
