there's a regulation in the michigan vehicle code that states headlights have to be 24" off the ground at center... i was planning on a car with 15" wheels (maybe 16" for the street, to up the ride height a bit) and 24" off the ground is going to make for some funky fenders with the "DSR" style i'm trying to go for.
What size tires are you planning to run on your 15" or 16" wheels? Most people are going to pick a 24-25" tire . . . But yes, pure DSR style is going to be difficult.
Can headlights be in "unique" locations? Say on the Main Hoop, projecting out over your head? That probably has a lot of other issues and is only a random idea.
