THIS, so much THIS ^^^
We just borrow everything we can. We have 1 set of Saturday night tires. We have 1 set of free tires we scrounged from people to run PA Burris. We run a 14 year old chassis. We borrow gears, we borrow air, we find people to scale us and set our toe/caster/camber. We borrow flashlights to see in the dark, we don't own an enclosed trailer, mostly just use the bed of the truck or I have a flat trailer someone bought us to pull with the car. We hit local businesses for the $32 fee to get in to race in exchange or parade showings or passing out fliers, or we donate plasma or we cut someone's grass off of craigslist or whatever we can do to make money to race. We sleep in the car or a tent at multi day events. We hustle and we have fun.
BTW, we won 13 times this past season.
