Need some help

Looking to race the fastest car I have up against an experienced builders car to see where I stand. Has to fit on a hotwheels Orange track and be 150g or less. If interested let me know and I'll give you an address to send the car. When the race is done I'll post the race on YouTube and I'll send your car back with a gift as a thank you. It's not a competition, just a way for me to gauge how my builds are going.
