CarbonXtreme BMW G82 M4 M Style Carbon Fiber Rear Spoiler
Born in the Workshop, Proven on Track
From our family molds to your G82 M4, the M4 carbon rear wing by CarbonXtreme carries over 15 years of in-house carbon fiber mastery. We don’t rebrand—every curve, layup, and clear-coat step happens under our roof, just as we’ve supplied to private racing teams and OEM programs.
Purpose-Driven Aero
This wing isn’t just for show. Its high-lift profile and integrated support ribs are shaped by CFD insights and real-world testing, delivering measurable rear downforce without harsh drag. During spirited sprints or track days, you’ll feel the difference in stability and rear-end grip—because we refine each angle on club circuits before ever shipping a part.
Seamless OEM Integration
No fillers, no hacks—just direct-bolt installation using your G82’s factory trunk mounts. Precision-machined bases and supplied stainless hardware guarantee a gap-free fit that preserves the trunk’s original lines. In minutes, transform your stock decklid into a purposeful performance spoiler.
Durable & Distinctive
Finished in UV-resistant high-gloss clear coat, this wing keeps its deep carbon texture vivid, mile after mile. Its dry-carbon construction handles heat cycles and weather extremes, offering lasting beauty and function—exactly what serious drivers expect from CarbonXtreme.
Whether carving canyons or commanding a pit lane, the M4 carbon rear wing blends motorsport pedigree with street-legal convenience. It’s more than a spoiler—it’s CarbonXtreme craftsmanship, track-tuned for your everyday drive.

Engineered to fit from day one
Built from OEM geometry and on-car scans, refined through multiple prototype corrections, then produced with metal tooling and jigs that control mounting-hole positions, edges and curvature. Each batch undergoes dimensional sampling so parts leave the line aligned to factory contours—reducing install effort and eliminating product-caused fitment issues.
Finish standards: flatness first
Many can get the structure right; few invest to make the surface look truly premium. We spend on interlayer leveling, fine sanding, multi-coat clear coat and controlled curing: straight reflections under strong light, crisp weave definition, and long-term resistance to UV yellowing, hazing and cracking. That’s the visible difference.
Delivery & support: fast and worry-free
A specialist replies within 2–8 hours after purchase. In-stock items ship within 2–3 days following final inspection (QC) and reinforced packing, with end-to-end tracking. Before dispatch, every unit receives a final inspection—jig-based mounting-hole/fit checks and bright-light surface review—to catch issues before they travel. If installation proves tricky, our engineering and support teams will assist, and any shipping issues are prioritized. Faster handoff and dependable service save you time and friction.
Make every exit an entrance
Upgrade with Confidence
Precision in Every Layer
For enthusiasts with higher expectations, we also offer a premium upgrade option: the Glasurit 923-447 (BASF) clear coat. Known for its scratch resistance and micro self-healing capability, this finish minimizes swirl marks under sunlight and delivers a showroom-grade gloss. Due to its demanding spray conditions and extended curing process, this option requires longer lead times and accounts for roughly 30% of the product’s value. It is reserved for customers who seek uncompromising quality and perfection.
No matter which option you choose, CarbonXtreme ensures that every piece reflects our pursuit of excellence—combining aesthetics, durability, and performance in one.
FAQs
Please read our FAQs page to find out more.
Will this fit my exact model, trim, and year (LCI/Pre-LCI, M Sport vs. base)?
Yes—fitment follows OEM geometry. At checkout we require your vehicle details (model/year, trim, LCI/Pre-LCI, bumper type/photos) and perform a second verification. If your selection doesn’t match your vehicle, we’ll alert you before fulfillment to correct it.
What if I have aftermarket bumpers or prior bodywork?
Aftermarket bumpers and vehicles with prior collisions or repairs (even minor scrapes) can alter mounting geometry, which may cause installation difficulty. We’ve seen cases where a previous accident left the bumper deformed, making parts hard to seat—this is not a product defect. Please have your installer inspect mounting points before ordering.
Do I need to drill or cut?
Dry carbon: installs via factory mounting points; no drilling is generally required, except some rear wings that may require trunk drilling.
Wet carbon: due to process characteristics and possible deformation during transit or humidity changes, self-tapping screws may be needed to secure fitment.
Will the carbon tone match if I replace a single piece later?
Single-piece replacements are available. Minor batch-to-batch tone variance is normal; for perfect symmetry on L/R paired parts, replacing as a set is recommended. If you purchased from us and later damaged a part in a collision, send photos— we can usually offer a returning-customer discount on the replacement.
Will sensors, radar, PDC, and tow-hook access still work?
Some carbon grilles include pre-cut radar/PDC windows. Please review product photos carefully or provide OEM front-end photos before ordering. We typically re-confirm before shipment. If a misread leads to the wrong variant being ordered, exchanges are possible, but additional shipping costs may apply.
Can I choose gloss vs. matte or request specific finish options?
Standard is multi-layer BASF (Glasurit) gloss. Matte clear and special finishes can be built to order; lead time will differ.
What’s included in the box? Will I need extra hardware or tape?
Each product page lists what’s included. Vehicle-specific clips/brackets are included when required; high-bond tape or fasteners are provided where applicable. If an item needs OE hardware reuse, we’ll state it clearly.
What happens if my item arrives damaged?
You’re covered. Contact us within 48 hours with photos of the outer box, inner packaging, labels, and the part. We’ll arrange a replacement or a fair resolution at no extra cost. Keep the packaging until we confirm next steps.
What payment methods do you accept? Is it secure? Under which law?
We accept PayPal and Useepay, settling in USD via secure gateways with industry-standard encryption and fraud screening. Our Terms are governed by UK law.
