I remember Sport Compact Car magazine advertised that 10 years ago. You are wasting your time, you have to attend X amount of car shows, provide your own engine blocks if you choose racing, their terms were thee absolute worst. The only reason why you would need a sponsorship is if you plan on taking your car to extremes and driving across the USA on their "terms".
Like cars featured on Honda Tuning and Super Street, they look great, but their not daily drivers and lots of money was put into them
Unless you plan on replacing blocks every race season, ask a local drag racer who has a "fast" car, like under 10sec in the 1/4 or 7sec in the 1/8th of how many parts and engines they build for a season, not worth it to me
