💡 Quick Answers

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 get 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 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.
