{"product_id":"mmx-performance-f2x-f3x-billet-differential-insert-set","title":"MMX Performance F2X \/ F3X Billet Differential Insert Set","description":"\u003cp\u003eThe MMX Performance billet differential insert kit is the companion upgrade to the rear subframe insert set, and on a lot of F-chassis BMWs, the more impactful of the two for daily and track driving. The factory rear differential is rubber-mounted to the subframe for ride comfort, which under hard acceleration and braking lets the diff shift in its mounts. That movement translates to wheel hop, less consistent power delivery, and a less precise feel through the seat of your pants.\u003c\/p\u003e\n\n\u003cp\u003eThe MMX inserts are precision-machined from billet aluminum to fill the voids in the factory rubber differential mounts. They limit diff deflection under load while leaving enough rubber in place to retain refinement and prevent NVH issues. The result is a tighter, more direct connection between the engine, the diff and the rear wheels, without sacrificing day-to-day ride comfort.\u003c\/p\u003e\n\n\u003cp\u003eBehind the wheel: noticeably reduced wheel hop on hard launches, cleaner power delivery on corner exit, and a more positive, predictable rear-end feel under both throttle and engine braking. It is one of the highest-return chassis tweaks on the F-chassis platform.\u003c\/p\u003e\n\n\u003cp\u003eInstallation is straightforward (under an hour with basic hand tools) and is completely reversible. No press required, no permanent modification, no need to drop the diff or subframe.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision-machined billet aluminum inserts\u003c\/li\u003e\n  \u003cli\u003eFills factory rubber diff-mount voids: does NOT replace the rubber\u003c\/li\u003e\n  \u003cli\u003eLimits differential movement under throttle and braking loads\u003c\/li\u003e\n  \u003cli\u003eReduces wheel hop and improves power-delivery consistency\u003c\/li\u003e\n  \u003cli\u003eAnodized finish\u003c\/li\u003e\n  \u003cli\u003eSKU MMR12-6001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVehicle Applications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/1-series-f20\"\u003eBMW 1 Series (F20 \/ F21)\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/2-series-f22-f23\"\u003eBMW 2 Series (F22 \/ F23)\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/3-series-f30-f31\"\u003eBMW 3 Series (F30 \/ F31)\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/ind-distribution.com\/collections\/4-series-f32-f33\"\u003eBMW 4 Series (F32 \/ F33)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIncludes a 1-year manufacturer warranty against defects in materials and workmanship\u003c\/li\u003e\n  \u003cli\u003eDesigned and tested in the United Kingdom\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IND Distribution","offers":[{"title":"Default Title","offer_id":47411574112450,"sku":"MMR12-6001","price":163.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/0784\/7874\/files\/53331666308_8e0c16d298_b.jpg?v=1778613020","url":"https:\/\/grocerygetterperformance.com\/products\/mmx-performance-f2x-f3x-billet-differential-insert-set","provider":"Grocery Getter Performance","version":"1.0","type":"link"}
