The winners of any design chosen by 925NEVER Racing will be paid per design chosen. We are looking for thematic shirts that embrace the roots of auto racing especially runnin shine, chasing loose women, scars, glory and southern rock. This work will need to be done in a vector art format (.ai or .eps preferably). We would advise using racing/souther rock colors (black base, red, blue, silver etc.). If you would like a copy in vector format of our pre-existing log to base your design off of please email firstname.lastname@example.org to request the logo.
