u can race at any age from what i know, the more older you are the biggercc class you will be in,if your considering racing your blaster you will need more parts becuz they are heavily modded.
nerfbars, skill so u won't crash,time to travel around, money to buy parts and gear,i think you are reqired to remove your headlight??, like jlsparky said a tether kill switch (shuts the engine off), front bumper might be useful, numberplate, and tons of mods
