Kyosho Fazer Lowered Suspension Arms (7.5mm drop)

thingiverse

Hi guys, These are custom suspension arms for the Kyosho Fazer MK2 platform. They provide better handling when running 90mm or larger 4WD buggy tires. Check out some run vids: Stock, big tires, gravelly mayhem - https://www.youtube.com/watch?v=l7sIl52AzcU Stock, big tires, high speed fails - https://www.youtube.com/watch?v=Dvps0_yi-nk Stock, big tires, dirt running - https://www.youtube.com/watch?v=ST9SEHwGFSc I'll be posting footage of the car running suspension mods soon. With these arms, you can run high top speed with confidence. To install, use the stock rear arm with the stock knuckle. If you're using my printed knuckle, attach the other arm to capture the pin. You'll need an M3 screw in the loose end. These arms add about 3 degrees of camber and outward toe in the front, making the car much more stable in a straight line when running a hotter than stock motor or 3S. Be careful not to push it too hard - the car can roll easily at high speeds. The overall handling is not bad, but it's a bit loose on most surfaces except grass. You have to respect the speed limit or you'll end up with some big rolls. The stock setup with big tires isn't bad if you're going slow, but these arms make a huge difference when you're going faster. Interestingly, I think the car is slightly looser with these arms on very loose dirt type surfaces, but it may just be that it's easier to get it going too fast. Even if it is looser, it doesn't roll as easily, so I'll take the trade-off. I printed these arms using TPU (Solutech flexible filament) and they're extremely tough. That's why they have a wedge shape - with TPU, you want to eliminate as much flex as possible without adding bulk. I think these arms are stiff enough, but judge for yourself. If they flex too much, you risk a hard lateral impact compressing the suspension and mashing the dog bone into the drive cups, potentially damaging the diff. Use at your own risk. Choose wisely - wrench to drive or drive to wrench?
