Mini 4WD front carbon fiber parts. This combines a hinge-type AT mechanism and independent left/right sliding dampers. Made with genuine Tamiya carbon fiber and precision CNC machining (with some hand adjustments). Designed and manufactured as a prototype, but available for sale to those who need them. <Hinge-Type AT Mechanism> Based on the convenience and proven performance of the CH-Fix series of hinge-type movable parts, this has been adapted for a front AT setup. Instead of sliding movement in the axle holes, the hinge structure allows for very smooth movement. Since it can be fixed with a hinge, you don't have to worry about the cut lines on the chassis. - The angle when the hinge is open is approximately 30 degrees. - Please insert any desired spacers into the gap of the hinge. - Due to the structure, thrust will not be lost. - A 3mm thick carbon fiber is used for the bumper plate and processed three-dimensionally with CNC. A 4-degree slope is applied to the top surface, so you can secure the thrust angle as is. Please slope the bottom surface according to your car height and brake settings. - There is no function to hold with springs, etc., so please consider separately according to your own machine settings. (Although you can usually run without holding, the settings will be more sensitive if you use it with an AT-linked lantern.) - The hinge fixing nut part tends to interfere, so please adjust it. - As a bonus, 6 hinge fixing parts are included. They can also be attached to other bumper plates. <Independent Left/Right Sliding Dampers> - The left and right slide stays move independently. The range of motion is designed to be wide at 4mm. - Based on the same concept as the SD-Fix, which is sold separately, it has a circular arrangement/circular movement layout. - Brass spacers are not included. Please prepare cut ones separately. <Other, Assembly Instructions, etc.> - Assemble the carbon fiber parts and 1.4mm hollow shafts with reference to photos 10-14. - Springs, screws, and nuts are not included. Please prepare them separately. - Please check the other specifications and conditions in the photos (surface matte finish). ■ Only the set of parts in photo 7 will be sent. Those who are extremely sensitive to the appearance, please refrain from bidding. Returns and support are not available. Please consider only if you can process carbon fiber and make fine adjustments yourself. Please bid after understanding these points.
