Those rims will most likely not fit. 1/10 buggies use the same hexes as most other 1/10 scale rc's like the rustler, etc. Although sometimes, a hex isn't even needed, and the pin that goes through the axle will fit right into the rim. Regardless, the tires from your 8ight will not fit either, because the Brama uses 2.2 rims as far as I know.
