New, these bushings provide smooth, vibration-isolated shifter movement. Over time, the rubber softens, compresses, and cracks — the result is lateral play, front-to-back slop, and a vague, imprecise shift feel where the shifter moves noticeably before engaging a gear. On a used STI, worn shifter bushings are one of the most common causes of a notchy or imprecise shift feel that can be mistaken for transmission wear. Replacing the bushings is typically the first and most cost-effective step before suspecting the transmission itself.\u003c\/p\u003e\n\u003ch3\u003eGrimmSpeed Bushing Kit — Firmer, More Direct Shift Feel\u003c\/h3\u003e\n\u003cp\u003eGrimmSpeed’s bushing kit replaces the OEM rubber bushings with precision-fit aftermarket bushings that eliminate the rubber compliance responsible for shifter slop. The result is a noticeably more direct, gate-defined shift feel — less throw vagueness, better gear location confidence, and a shorter effective shift arc. The shift feel will be firmer than OEM — this is the intended outcome. Buyers accustomed to the soft feel of a stock STI shifter should expect a more mechanical, precise character after installation, which is the goal of the upgrade.\u003c\/p\u003e\n\u003ch3\u003e2004–2021 STI 6-Speed Coverage\u003c\/h3\u003e\n\u003cp\u003eThe Subaru STI has used the 6-speed manual (6MT) continuously from the 2004 GD\/GG-generation through the 2021 VA-generation. The shifter and linkage bushing geometry is consistent across all three chassis generations — GD\/GG (2004–2007), GR\/GH (2008–2014), and VA (2015–2021) — which allows a single kit to cover 17 years of STI production. The WRX used a 5-speed in earlier years; later 6-speed WRX owners should verify compatibility before ordering.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eSTI 6-speed manual only. Shift feel will be noticeably firmer than OEM after installation — this is the expected result. Lubricate bushings with appropriate grease during installation. Inspect shift linkage and rod ends for additional wear while the linkage is disassembled.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: GrimmSpeed\u003c\/li\u003e\n\u003cli\u003ePart Number: GRM.1153.1.0\u003c\/li\u003e\n\u003cli\u003eType: Shifter bushing kit\u003c\/li\u003e\n\u003cli\u003eTransmission: 6-speed manual (6MT)\u003c\/li\u003e\n\u003cli\u003eWeight: 1.5 lbs\u003c\/li\u003e\n\u003cli\u003eApplication: 2004–2021 Subaru STI — GD\/GG, GR\/GH, VA chassis\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":51325023846567,"sku":"GRMGRM.1153.1.0","price":50.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/8344\/1063\/files\/5c4181ef097b6f4db44e350707bf8ac7L.jpg?v=1789041520","url":"https:\/\/www.straightsiximports.com\/en-us\/products\/grimmspeed-04-21-subaru-sti-6-speed-shifter-bushing-kit","provider":"Straight Six Imports","version":"1.0","type":"link"}
