This tucked geometry limits overall track width, increases body roll through dynamic transitions, and restricts clearance when fitting oversized performance brake calipers or wider performance tires. Additionally, cheap non-hubcentric universal spacers cause severe wheel runout, high-speed harmonic vibrations, and dangerous shear loads on wheel studs due to improper hub engagement.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 15mm spacer kit is CNC-machined from high-tensile \u003cstrong\u003e7075-T6 billet aluminum\u003c\/strong\u003e, providing significantly higher yield strength and shear resistance than entry-level 6061 alloys. Integrated weight-reduction pockets eliminate unnecessary unsprung rotational mass without compromising rigidity. Precision-engineered with a 71.6mm center bore and factory-spec hubcentric lip, the kit ensures complete radial load transfer directly to the hub snout rather than relying on fasteners alone. Accompanied by extended OEM-style Grade 10.9 wheel bolts to guarantee factory-spec thread engagement.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eHubcentric 15mm 7075-T6 wheel spacers\u003c\/li\u003e\n  \u003cli\u003eExtended OEM-style wheel bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1997-2025 Porsche 911, Boxster, Cayman\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eM96, M97, MA1, 9A2 \/ 996, 997, 991, 992, 986, 987, 981\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e201 - 640 hp \/ 181 - 590 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePorsche 911 (996, 997, 991, 992 generations)\u003c\/li\u003e\n  \u003cli\u003ePorsche Boxster (986, 987, 981 generations)\u003c\/li\u003e\n  \u003cli\u003ePorsche Cayman (987, 981 generations)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the 996, 997, 991, 992, 986, 987, and 981 chassis?\u003c\/h4\u003e\n\u003cp\u003eYes, this kit is engineered for 1997-2025 Porsche sports cars with a 5x130 bolt pattern and 71.6mm hub bore. \u003cstrong\u003eThis kit does not fit Porsche Macan chassis.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat torque specifications should be used during installation?\u003c\/h4\u003e\n\u003cp\u003eTorque the included extended bolts to factory Porsche specification (typically 96 to 118 lb-ft depending on generation) using a calibrated torque wrench, and re-torque after 50 to 100 miles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Porsche Precision Standard\u003c\/h3\u003e\n\u003cp\u003eGerman sports car suspension geometry requires micron-level machining tolerances to eliminate high-speed harmonic imbalances and preserve communicative steering rack feedback under heavy track braking.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67558910460152,"sku":"DS-EJ3AK4FV3","price":419.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/hubcentric-wheel-spacer-kit-for-porsche-911-boxster-cayman-1997-2025-15mm-1.jpg?v=1790926041","url":"https:\/\/performancechiptuning.com\/products\/hubcentric-wheel-spacer-kit-for-porsche-911-boxster-cayman-1997-2025-15mm","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
