Frequently Asked Questions
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 Rear Spats are designed to fit both versions.
Do I need to remove my rear bumper to install these?
No, you do not need to remove your rear bumper. The entire installation can be done from the underside of the vehicle with the rear bumper still attached.
Can I run these with your Rear Diffuser Fins?
Yes! In fact, LVA highly recommend pairing these Rear Spats with LVA's 4-Piece Rear Diffuser Fins for a complete rear-end aero setup.
