too much carbon fiber is never over kill
My old car, I had a carbon fiber headliner, dash, and other pieces. Other half of car was glazed and painted to make the car look like a two tone interior "one being a color other being carbon fiber"
But what ive done so far isnt too much.... Just simply replaced the factory leather areas with carbon fiber. Anybody else would have redone those areas with colored leather or cloth. Its not an eyesore whats so ever.
