FAQ

What's the difference between the Base and Premium rear bumper?
The Premium bumper is a 2-piece unit with body color painted portions and some textured black plastic. The Base bumper is a single-piece unit. These Diffuser Fins were designed specifically for the Premium bumper, though many customers have successfully installed them on the Base bumper as well.
Will these interfere with my exhaust tips?
No, these diffuser fins are designed to mount between and around your factory exhaust tip locations. They will not interfere with stock or most aftermarket exhaust setups.
Can I install these myself or do I need a professional?
While professional installation is always recommended for optimal results, these diffuser fins can be installed at home with basic hand tools. The included L-brackets and hardware make for a straightforward bolt-on installation process.
Made to order in the USA. Each LiquiVinyl piece is hand-built to your order — please allow 2–3 weeks for production. By placing your order you acknowledge and agree to this build time.

💡 Quick Answers

FREQUENTLY ASKED QUESTIONS

📦 What happens after I order? +

You'll get an instant confirmation email with your part details and invoice. We source from a network of authorized suppliers across the country, so lead times vary by brand and part type — we'll send a tracking number the moment your parts move.

Made-to-order builds — carbon fiber bodywork, fabricated systems, custom finish work — run longer than off-the-shelf items because they're built per order. You'll get progress updates throughout the build.

Need a specific timeline on a part before you buy? Call 805-267-9762 or hit the chat — we'll check vendor stock direct and give you a straight answer.

🚚 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.

What can I do to help FFP? +

Simple — spread the horsepower! Follow us on Instagram, YouTube, and Facebook, and most importantly, drop us a review on Google or Yelp to let others know about your experience.

Your feedback helps us grow, create more content, and keep bringing performance-driven parts to the community. 🏁
