Upgrade Guide
How Enthusiasts Plan Their Exterior Upgrades
Most builds start at the front. A bumper conversion kit delivers the single biggest visual change per dollar — an F22 wearing an M2-style front end or an F30 with M Sport rear styling reads like a different car. Because body kits ship unfinished, plan for professional paint and installation, and confirm parking sensor (PDC) and fog light options on the product page before ordering.
Weight and heat come next. A carbon fiber or vented hood trims front-end weight and vents engine bay heat, which matters in hot climates like Arizona and Texas. Pair it with vented fenders if you're running wider wheels or want the full wide-body silhouette.
Aero and lighting finish the shell. A rear spoiler or GT wing adds downforce and a purposeful profile, while sequential LED tail lights modernize any rear end in an afternoon. For Tesla owners, dry carbon mirror covers and dashboard trim kits from FYBR Aerodynamics deliver autoclave-cured quality with 3M peel-and-stick installation.
Don't forget the one part you touch every drive: a motorsport steering wheel in carbon and alcantara changes the feel of the car more than any panel. Whatever order you build in, every part in this catalog is chosen for OEM+ fitment — so your body shop spends time painting, not persuading panels to line up.
Questions Answered
Automotive Upgrade FAQs
The questions we hear most before someone pulls the trigger on their first exterior upgrade.
What's the difference between dry carbon and wet carbon fiber parts?
Dry carbon is cured under heat and pressure in an autoclave, producing a lighter, stronger panel with a tighter weave and less resin. Wet (hand-laid) carbon is heavier and more affordable. Where a part is offered in dry carbon — like our FYBR Aerodynamics mirror covers — we call it out in the listing.
Will aftermarket bumpers and hoods fit like factory parts?
We prioritize OEM+ fitment, meaning parts are designed to mount to factory locations with factory-style gaps and reuse OEM hardware. Bumper conversion kits ship unfinished and require professional paint, and we recommend professional installation — each product page spells out the details for your model.
Are LED tail light upgrades plug-and-play?
Most of our LED tail lights use factory connectors for plug-and-play installation. Certain vehicles may need a resistor or hyper-flash module, and each listing spells out what's included for your model.
Do you carry parts for specific makes like BMW, Tesla, or Cadillac?
Yes. The catalog includes model-specific applications — BMW M-style bumper conversions for the F22, F30, F32, and E46 chassis, Tesla Model X and Model Y dry carbon accessories, and Cadillac CTS-V style front conversions — alongside universal upgrades like spoilers and steering wheels. Always confirm the year and trim listed on the product page.
How fast do performance parts ship?
In-stock parts ship within 1–2 business days in recyclable packaging, with no EU import duties. Shipping is calculated at checkout, and select carbon fiber accessories qualify for free shipping.
What payment methods do you accept?
We accept all major payment options through secure Shopify checkout, including Visa, Mastercard, American Express, Discover, PayPal, Apple Pay, Google Pay, and Shop Pay.
