Machined from aerospace-grade billet aluminum, this hub is engineered specifically for 30mm axles and mates perfectly with 505 Series rotors (1\/8\" x 6.0\", 1\/8\" x 7.1\", and 3\/16\" x 6.0\"). When you are diving deep into the apex, the last thing you want is rotor wobble or hub flex compromising your modulation. This precision-machined component ensures maximum energy transfer from the caliper to the track surface, giving you the confidence to brake later and carry more rolling speed through the corner.\n\n\u003ch2\u003eOptimizing Your Chassis Beyond the Brake Hub\u003c\/h2\u003e\n\u003cp\u003eA responsive braking system is only one piece of the puzzle when dialing in your setup. To maximize the deceleration forces generated by this billet hub, your body positioning and weight transfer must be locked in. Upgrading your \u003cstrong\u003ego kart seats\u003c\/strong\u003e ensures you stay planted during high-G braking zones, preventing unwanted chassis bind. Similarly, balancing your kart's weight distribution by strategically mounting your \u003cstrong\u003efuel tanks\u003c\/strong\u003e can dramatically improve rear-end stability under threshold braking.\u003c\/p\u003e\n\n\u003ch2\u003eSeamless Integration with High-Output Powerplants\u003c\/h2\u003e\n\u003cp\u003eWhen you bolt on a high-RPM \u003cstrong\u003ekart racing motor\u003c\/strong\u003e, your terminal velocity at the end of the straightaway increases exponentially. Factory cast hubs simply cannot dissipate the thermal load or handle the rotational stress generated by these speeds. The MCP billet hub reduces unsprung mass while increasing tensile strength, ensuring your rotors stay true even when glowing hot. Note that assembly requires three MCP526 drilled bolts (sold separately) to secure the rotor to the hub.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAerospace-Grade Billet Aluminum:\u003c\/strong\u003e Drastically reduces unsprung rotational mass for quicker acceleration and responsive suspension tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExact 30mm Axle Bore:\u003c\/strong\u003e Precision-machined tolerance eliminates keyway slop and prevents rear axle scoring under heavy braking loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e505 Series Rotor Compatibility:\u003c\/strong\u003e Seamlessly accepts 1\/8\" x 6.0\", 1\/8\" x 7.1\", and 3\/16\" x 6.0\" mini-lite brake discs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Thermal Dissipation:\u003c\/strong\u003e Billet construction pulls heat away from the rotor faster than cast alternatives, preventing fluid boil.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree-Bolt Mounting Pattern:\u003c\/strong\u003e Utilizes standard MCP526 drilled bolts (not included) for secure, vibration-free rotor attachment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Pad Wear:\u003c\/strong\u003e True-spinning hub design guarantees parallel rotor alignment, extending the life of your brake pads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMini-Lite Class Legal:\u003c\/strong\u003e Meets the stringent dimensional requirements for competitive sprint and club racing categories.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWhether you are piecing together a custom build or upgrading your current race rig, the MCP 30mm Billet Brake Hub is the foundation of a championship-winning brake package.

You will need three MCP526 drilled bolts to secure your 505 Series rotor to the hub. Please note that these bolts are sold separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why should I choose a billet hub over a standard cast hub?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Billet aluminum offers superior tensile strength and thermal dissipation compared to cast alternatives. This reduces unsprung mass, prevents rotor wobble under heavy braking, and helps keep your brake fluid from boiling during intense racing sessions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Which rotors are compatible with the MCP 505 Series Billet Brake Hub?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e This hub is engineered to mate perfectly with 505 Series rotors, specifically the 1\/8\" x 6.0\", 1\/8\" x 7.1\", and 3\/16\" x 6.0\" sizes.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will this hub help with my brake pad wear?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes. Because this hub is machined to exact tolerances, it ensures true-spinning, parallel rotor alignment. This prevents the rotor from \"wobbling\" against the pads, which promotes even pad wear and more consistent braking modulation.\u003c\/p\u003e\n\n\u003ch3\u003eRelated Products From Vendor\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/mini-lite-brake-pad-blue-each-high-performance-mcpbpml-hp\"\u003eMCP Brakes Mini-Lite High-Performance Blue Brake Pad - Sold Individually - Go Kart Racing\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SwiftKarting","offers":[{"title":"Default Title","offer_id":52378344882495,"sku":"BBH30MM-505","price":43.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/6843\/4239\/files\/mini-lite-billet-30mm-brake-hub-for-505-series-rotors-bbh30mm-505_bfcbb7b9-20e0-46a8-aac2-de84939a495e.jpg?v=1773221342","url":"https:\/\/metro-merch-3.myshopify.com\/products\/mcp-brakes-505-series-billet-brake-hub-30mm-axle-3-bolt-mini-lite-sprint","provider":"Metro Merch","version":"1.0","type":"link"}
