BMW G87 M2 OEM Style Carbon Fiber Rear Diffuser
Enhance Rear Aerodynamics and Aggressive Styling
Transform your BMW G87 M2’s rear-end presence with the CarbonXtreme G87 M2 rear diffuser—an OEM-style dry carbon fiber component meticulously engineered to bolt directly into your factory bumper cutouts. This diffuser insert delivers genuine aerodynamic benefits by managing underbody airflow, reducing rear-end lift, and accentuating the G87’s performance-oriented silhouette. At first glance, the G87 M2 rear diffuser commands attention with its multi-fin geometry, precision carbon weave, and mirror-like UV-resistant gloss finish—every detail speaks to CarbonXtreme’s commitment to both form and function.
Constructed from pre-preg dry carbon fiber and cured in an autoclave for maximum rigidity, this diffuser insert mirrors the original OEM diffuser shape while adding extra depth and dimension. The carefully contoured fins and channels are designed to funnel turbulent air away from the rear underbody, creating a smoother exit path for high-velocity airflow. By doing so, the G87 M2 rear diffuser helps improve high-speed stability—particularly valuable during track sessions or spirited driving on backroads. In addition to its functional enhancements, this dry carbon insert lowers your G87’s overall weight compared to factory plastic components.
Installation is seamless: the G87 M2 rear diffuser utilizes the OEM mounting points and hardware, requiring no cutting, trimming, or modification to the rear bumper support structure. Simply remove the factory diffuser cover, align the CarbonXtreme insert with the existing bumper tabs, and secure with the provided stainless-steel hardware. The precision-milled edges ensure gap-free alignment and a flush finish. Once installed, the lightweight dry carbon fins hug the G87’s rear bumper, offering a track-ready stance that stands out in any parking lot or paddock.
For a cohesive, full-car transformation, the G87 M2 rear diffuser pairs flawlessly with CarbonXtreme’s G87 M2 Upgrade to M2CS Full Aero Conversion Kit – 5-Piece Set. That comprehensive kit includes the CS-style front grill, front bumper vents (SQ or MP style), lower front grille, rear trunk panel, and this very rear diffuser—delivering a complete front-to-rear performance and styling package.
Whether you’re building a dedicated track monster or fine-tuning a show car for concours events, the G87 M2 rear diffuser brings CarbonXtreme’s high-standard craftsmanship to your M2. Every component is inspected under polarized lighting to guarantee a uniform carbon weave, smooth edges, and flawless clear-coat finish. Experience reduced lift, improved airflow, and head-turning rear-end style—all thanks to this bolt-on dry carbon fiber upgrade.

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.
