This kit addresses the three most common weak links in the G87 M2, G80\/G81 M3, and G82\/G83 M4 drivetrain: oil starvation, differential movement under load, and heat soak during extended sessions. By reinforcing the diff system from multiple angles, it ensures consistent performance even during long high-G stints.\u003c\/p\u003e\n\u003cp\u003eAt the core of the package is the high-capacity billet differential oil pan, CNC-machined from 6061-T6 aluminum and capable of increasing oil volume by up to two liters. Internal and external cooling fins, combined with an integrated windage tray, help stabilize temperatures and maintain lubrication during aggressive cornering. The included dual differential mount further enhances stability by minimizing housing flex, keeping the drivetrain aligned under heavy braking, cornering forces, and hard acceleration.\u003c\/p\u003e\n\u003cp\u003eTo combat heat saturation, MMX includes a rear differential output shaft heat-shield set, custom-formed to protect surrounding components from excessive thermal load. Together, these upgrades significantly reduce the chances of triggering “Driving Stability Limited” warnings and improve drivetrain consistency during repeated hot laps.\u003c\/p\u003e\n\u003cp\u003eCompatible with the G87 M2 and G80\/G81\/G82\/G83 M3\/M4 platforms—both RWD and xDrive—the Track Pack delivers a major step up in durability and confidence. Pairing these components with proper fluids and torque-spec checks ensures maximum performance and long-term reliability for any G8X used in serious track environments.\u003c\/p\u003e","brand":"MMX Performance","offers":[{"title":"Default Title","offer_id":49647225864438,"sku":"MMR55-1600KT","price":2747.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2674\/6278\/files\/54931586127_de2b43ddcb_b.webp?v=1764019942","url":"https:\/\/autotecknic.com\/products\/mmx-performance-ultimate-differential-track-pack-g8x-m2-m3-m4","provider":"AutoTecknic USA","version":"1.0","type":"link"}
