Its dynamic lug-drive system lets the rotor move independently of the hat as it expands and contracts through repeated heat cycles, removing thermally generated stress from the rotor attachment points so the rotor stays flatter and runs truer with consistent brake response and pedal feel. Spring-loaded replaceable stainless steel inserts protect the aluminium hat from wear, and a single snap-ring retains the rotor without conventional rotor mounting bolts.\n\n### Key Features\n\n- Dynamic lug-drive rotor mounting system\n\n- Rotor moves independently of the hat during thermal expansion and contraction\n\n- Removes thermally generated stress from rotor attachment points\n\n- Helps rotors remain flatter and run truer\n\n- Maintains consistent brake response and pedal feel\n\n- Helps eliminate pad knockback and rotor drag\n\n- Prevents hat distortion caused by rotor thermal expansion and shrinkage\n\n- Eliminates bolt-hole alignment issues when mounting replacement rotors on previously used hats\n\n- Spring-loaded replaceable stainless steel inserts protect the aluminium hat from wear\n\n- Inserts protect against loading from the stainless steel rotor when brake torque is applied\n\n- Large single snap-ring retains the rotor in the hat\n\n- No need to torque or safety-wire rotor mounting bolts\n\n- Matching stainless alloy discs are drilled to reduce unnecessary rotating driveline mass\n\n### Specifications\n\n- Mount hole type: Lug\n\n- Rotor bolt circle: 12 Lug x 7.77 in\n\n- Hat offset: 1.330 in\n\n- Centre registration: 3.15 in\n\n- Material: Aluminium\n\n- Mount style: Dynamic Lug Mount\n\n- Finish: Type III anodised\n\n- Hat bolt circle: 6 x 5.50","weightGrams":1,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/wilwood-rotor-top-hat-dynamic-lug-drive-hub-170-18213","buyOneNow":null,"basketWithThis":null}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
