HEADS UP ON FIT
The connector has to match your car's radio harness. The IMSA and NASCAR kits are stereo wired and will NOT work with mono wired speakers. They pair with Zamp's 3.5mm Plug and Speakers (HACOM003).
FastLap Supply Take: Wrong connector is the number one comms headache. Check the car side first, then order.

Actually Measuring Your Head
Use a soft measuring tape (craft store, like $3). Wrap it around the widest part of your dome, forehead to back, and get the same number twice. Use that number to pick your size. Revolutionary, we know. lol.
