The Crc car simply works on carpet. There are a few option parts that are worth considering - getting a spool for black carpet would be a top concern. Still, there’s not a lot of extras needed. A couple parts like the ball studs for the side links and front steering arms and kingpins are good to have on hand.

At at the same time, if you are a driver who expects to assemble a car with zero effort and perfect parts fit, just realize it’s not an X-ray. Quality is very good, but a little extra care to make sure everything’s smooth and free will reap benefits. It’s also not a metric car excepting a few parts that interchange with Tamiya (wings, front end). Lots of 4-40 screws.
