Granite Granite to big rock conversion

[Billy p]

Is it true that I need the big rock's body and wheels and the long chassis with long driveshaft to convert my granite to a big rock?

You will need at least the long wheelbase chassis/driveshaft and body. The stock tires are different than the granite but you can still use them.

You are better off with the Granite tires. Unless you really want the BRCC tires.

Also the BRCC has different bumpers too.
