Frequently Asked Questions

How long does it take for my parts to ship?
If it’s in stock and ready to roll, your order usually hits the road within 1–3 business days.

For made-to-order or specialty items (like carbon fiber parts or custom builds), the turnaround can take up to 8 weeks — perfection takes time.

Either way, we’ll keep you updated so you know exactly when your parts are leaving the pit lane.
Do you send tracking with my order?
Absolutely. Once your order ships, you’ll receive an email with a tracking link so you can follow its journey from our shop to your doorstep.

If your order ships via freight, you’ll get a separate email with a direct link to the carrier’s tracking page — easy and stress-free.
What happens if my parts get lost or damaged?
Things happen on the road — even to boxes. If your order arrives damaged, snap a few clear photos of the box and product and send them our way right away.

If your shipment is lost, just email or call us — we’ll help track it down and guide you through the next steps to make it right.
