09 Frequently Asked
What’s the difference between DRYCF, FGCF, PCF, and FRP?
DRYCF is autoclave-cured dry carbon fiber — the most premium tier, lightest, with crisp visible weave. FGCF / FGPCF is forged carbon fiber — the marbled, chip-pattern look. PCF is a fiber-reinforced plastic substrate with a real autoclave carbon-fiber outer skin (lower cost, comparable look on visible side). FRP is the same FRP substrate without the carbon overlay — paint-ready unpainted finish.
Is this a real DarwinPRO part?
Yes. FFP is an authorized DarwinPRO dealer. Every order comes direct from DarwinPRO’s manufacturing pipeline. No counterfeits, no third-party copies.
What if it doesn’t fit?
DarwinPRO components are made to OEM body contours for the listed chassis and trim. Pre-order verification is on us — message before you order, and we’ll confirm. If a fitment issue does occur post-install, FFP coordinates the warranty claim directly with DarwinPRO.
How long is the lead time?
All material variants for this product are made to order at DarwinPRO’s manufacturing facility. Lead time: 6-7 weeks via air shipping (additional cost) or 3-4 months via container shipping (no extra freight). Updates provided every 2 weeks.
Can I install it myself?
Yes — DIY-friendly. Get the car on jack stands and you’re in business.
