Stewart Garage
Performance Parts Installations Done Right
Premium installs, built by an enthusiast—executed with a professional process.
Stewart Garage is the performance install division of Stewart Mobile Repair for drivers who want clean work done right. Performance parts don’t always bolt on perfectly, so we focus on fitment, routing, proper hardware, and correct torque—plus before/after photos and a test drive. Appointment-only, one project at a time.
The Benefits of Choosing Stewart Garage

Premium
Clean Workmanship
We focus on correct fitment, proper hardware, clean routing, and torque done to spec—so the install looks right and holds up.
MIG Steel Metalwork When Needed
If an install needs a clean bracket, tab, or small custom mount to be done correctly, we can handle MIG steel fabrication—so the final result is secure and professional (no improvised fixes).
Performance-Focused Experience
​Most standard shops are optimized for stock repairs. We work around aftermarket fitment, upgraded hardware, clearances, and the details that come with performance parts—so you get an install done with the right mindset and process.
One Project at a Time (Appointment-Only)
​Low volume means your car gets full attention—no rushed work, no bouncing between multiple vehicles, and no shortcuts.

Important Things

All installs include a 30-day / 1,000-mile workmanship warranty on installation-related issues, plus one post-install re-check (by appointment) when applicable.
Fitment & “Custom Work May Be Required”
Aftermarket parts can require minor adjustments for proper fitment (clearance, routing, hardware). If unexpected fitment issues appear, we’ll contact you before doing any additional work.
Deposits / Scheduling Policy
Appointments may require a deposit to reserve time. Cancellations or reschedules must be requested in advance.
Alignment Requirement
Any suspension change may affect alignment. A professional alignment is required after coilovers/suspension installs.
