We mainly want something that can be used on a t-shirt and as decals for cars. Multiple configurations are encouraged, allowing the logo to be flexible (used on a website, but also as a windshield banner).
The logo should definitely be meaningful. "Twitchy" is what our cars are. As you power through a corner, they begin to over-steer, the rear kicks out and the adrenaline flows faster. It takes skill to keep the tires planted. Some type of tire, skid marks, or a font that represents that (a hand written one, I used Bens Hand in my examples) is ideal. I'm open to ideas that may also portray anything 'twitchy'.
"Racing" is a bit more obvious. It is what we do and our logo needs to portray it. A checkered flag or pattern and/or a font that is professional.
Everything needs to be legible and multiple configurations are encouraged (single color for a vinyl, horizontal for a windshield banner, small for a patch, etc).
The final file needs to be AI vector format.
