Sunday Spec is part custom shop, part parts source, and part project partner for people who want more from their vehicles. We help customers choose the right components, make smarter upgrade decisions, and bring each project together through thoughtful planning, careful installation, and clear communication.

Sunday Spec was founded by David Crunkleton and Sean Parker, two automotive enthusiasts whose careers began in repair and performance shops while they were still in college. Their paths later brought them together at Vengeance Racing, where David worked in sales, marketing, and management while Sean developed his skills as a lead technician across production and race-focused projects.

After gaining additional experience in project management, product development, vehicle customization, and high-level automotive builds, David and Sean created Sunday Spec to offer enthusiasts a more complete and personal experience. Whether the vehicle is a daily driver, weekend car, classic, truck, SUV, or larger custom project, the goal is the same: help the owner create something more enjoyable, more capable, and more personal.
