Yep, the rear hub carriers and suspension hangers are a direct fit from the RB5. Im running all the aluminum off my RB5, even the battery posts.

What is a good starting setup for the car we run on 1/8 scale tracks so it tends to get blow out thanks

The manual recommends a 21-23 pinion when using a 8.5. Using a bigger pinion actually makes the car punchier and feels more powerful. I geared mine at 21 to give it a softer feel and it's still plenty fast.
