Frequently Asked Questions

Will this interfere with my trunk seal or create gaps at the bumper line?

The CT-R lip profile is designed to sit flush with OEM bumper geometry. Before installation, verify your bumper's mounting surface is clean and true. Any warping or damage to the factory bumper will cause misalignment—address that first to ensure a tight seam.

Should I glue this on or drill through for fasteners?

FRP lips perform best with both adhesive and mechanical fasteners. Use a quality automotive adhesive rated for composite-to-plastic bonding, then reinforce with fasteners at the factory mounting points. This dual approach provides long-term stability at speed and resists vibration loosening.

What kind of prep work does the Raw FRP finish require?

Sand the surface lightly with fine-grit sandpaper to open the primer coat and improve topcoat adhesion. Wipe clean with a tack cloth before painting. The primer layer seals the FRP and accepts color coat directly—no additional primer is needed if you're using standard automotive paint.

How To Get The Best Results

Duraflex is the go-to choice for builders doing a proper custom build using flexible fiberglass engineered to be shaped, fitted, and finished by a body shop. This is how serious aero work gets done.

The build process:

  • Sand and smooth the surface before fitting, which is standard for fiberglass aero
  • Test fit before you paint. Pros always do this, it's part of the process
  • Minor waves, pinholes, or uneven edges are normal and part of what your body shop will address during prep
  • Prime, paint, and finish to your exact spec and color

Best for:

  • Builds already going in for bodywork or paint
  • Projects where you want aggressive styling at a price that leaves budget for quality paint
  • Builders working with shops familiar with fiberglass aero, which is most of them

FAQs

Will this lip or diffuser fit my exact vehicle?

It's designed for the fitment listed on this page. If your model has multiple bumper options (M Sport, GT, RS), confirm which one you have before ordering — these are specific to the bumper style.

Does this ship painted or unpainted?

Most ship unpainted (raw composite, primer, or raw carbon). Some carbon fiber lips ship pre-finished with clear coat. The spec sheet on this page tells you what to expect.

Can I install this myself?

Yes — most lips and diffusers are bolt-on or 3M tape-on, 30-90 minutes with basic tools. Some require drilling, which is permanent, so check the spec sheet for the mounting method before you start.

How does shipping work?

Most lips and splitters ship standard parcel (UPS/FedEx). Larger one-piece splitters may ship freight. Either way, shipping covers insured delivery and damage replacement.

Roof rails a proper fit for my Ford Transit Connect - SWB. Some concern about the threaded connectors, wondering if rivnuts might offer stronger attachment.

Took 2 weeks to deliver with standard shipping. But well worth the wait. Install took 25 minutes with minimal tools and the lights look amazing. Fitment is perfect and the quality is excellent. Its kinda pricey but you get what you pay for with ntxglow products. Highly recommend!

Customer photo review of Spec-D Projector Headlights Ford F150 (04-08) Mark LT (06-08) Halo Black / Smoked / Chrome

They look amazing, and after using ChatGPT to help me understand how to install them (because the instructions were not very helpful whatsoever), I’m glad with how they turned out. My problems are that the lights aren’t too bright, the instructions weren’t helpful, and the arrival date was wrong, even if they arrived early.

Customer photo review of 1993-1997 Honda Del Sol Redclear Tail Light Lenses

This isn’t on K2, but the lenses came In which I was thrilled about. I’d already removed my OEM lenses from their housings. The passenger side lense fit well and mostly flush. The driver side, however, looks like it was slightly warped and caused poor fitment and what looks like a small dip in the red portion of the lense. I had no choice but to use them, as my OEM lenses were no longer usable. It can be very difficult to get replacement lenses in a timely manner for a Del Sol. I drive my car everyday, so I had to just go with it. Again, not a K2 issue but presumably the manufacturer.

Customer video review of 2003-2008 Nissan 350Z N4 Style Rear Bumper Cover - FRP

This rear bumper fits great the only thing is the trunk button on the bottom is cut a little to wide but that’s an easy fix it looks great and definitely makes the rear look more aggressive. I love it!

Customer photo review of Upgraded VANOS Oil Supply Line – M52 / M54 Engines (E36, E46, E39, E60, X3, X5, Z3, Z4)

The box was a little crushed, but the line was packed well and it wasn't a problem. The instructions are 3 pages of color pictures and lots of explanations. Very nice. The line itself is a very nice bit of kit with a swivel AN line end that allows a No-tension install. No leaks so far and it looks great. It came with new banjo bolts and copper crush washers. The only criticism I have is that I would have liked this hose coated in black so it disappears like the original, but it does look good, so I don't mind.

What to expect

Frequently Asked Questions

Will this fit my exact year, make, and trim?

Check the listed year, model, trim and body style before ordering. If you are unsure, email support@k2-industries.com with your vehicle details and the product link for help checking compatibility.

Do I need a body shop to install this?

Yes. Duraflex parts are engineered for professional prep, prime, and paint. They're built for builders doing a proper custom finish. Your body shop has almost certainly worked with Duraflex before, it's the most widely used fiberglass aero brand in the aftermarket.

What does the prep and install process look like?

Your shop will sand, test-fit, smooth any minor imperfections, prime, and paint to your exact color spec. Minor waves or uneven edges on raw fiberglass are completely normal and are addressed during prep, this is standard for any custom aero build.

How close will the panel gaps be?

Duraflex parts are designed to fit within acceptable custom aero tolerances. Because they're flexible fiberglass rather than OEM plastic, minor adjustments during fitting are normal and expected. Your body shop will dial in the gaps during the test-fit stage before paint.

What if my part arrives damaged?

Send us some photos. We ship a replacement. You don't file freight claims, you don't wait weeks, we handle it immediately.

Can I still get help after the part is installed?

Yes. Email support@k2-industries.com with your order number and installation question so our team can help.

What if it doesn't fit at all?

If there's a genuine fitment issue, not a prep issue, we make it right. Our team will work with you directly to find the correct part or issue a refund.

Can I pay in installments?

Yes, we offer flexible financing options to make it easier for you to upgrade your vehicle without paying the full amount upfront. Choose our financing option at checkout to split your purchase into manageable payments, so you can start your build now and pay over time.

How long will it take to receive my order?

It depends on where you are. Orders processed here will take 5-7 business days to arrive. Overseas deliveries can take anywhere from 7-16 days. Delivery details will be provided in your confirmation email.

Do you ship overseas?

Yes, we ship all over the world. Shipping costs will apply, and will be added at checkout. We run discounts and promotions all year, so stay tuned for exclusive deals.
