Yeah Racing Kyosho Fazer MK2 Aluminum Rear Upper Arms (Red)

These rear upper arms, like the front ones, provide much-needed camber adjustment for the Fazer. However, the installation is even more complicated. In my case, I had to remove the body mount just to access the turnbuckle. As with the front arms, I highly recommend disassembling them upon receipt, applying thread locker to all the screws and turnbuckles, and then reassembling everything. Skipping this step will likely result in extra frustration down the road.

The turnbuckles are directional, so the notch always faces the car regardless of the side, making tightening and loosening side-specific. It’s not as simple as forward expands and backward tightens—expect to rely on “righty tighty, lefty loosey.”

Unfortunately, I had to remove these due to interference with the rear spring. The fit was weird, and it didn’t work well with my setup. While they might solve camber issues and improve tire wear for some, I wouldn’t recommend them due to the fitment issues. Be ready for a tricky installation, and make sure to double-check compatibility with your specific build before buying. Not for the faint of heart!
