They've used the finest carbon fibre, combined with an exclusive resin which is non-combustible and thermally resistant to temperatures over 400°C (752°F). This special resin cures an attractive yellow or orange depending on the batch.\u003c\/p\u003e\n\u003cp\u003eThese don't just look the part though: initial testing carried out by a professional racing driver in various road and track conditions showed a \u003cstrong\u003ehuge average temperature drop of 49°C (120.2°F)\u003c\/strong\u003e on the front calipers.\u003c\/p\u003e\n\u003cp\u003eHEL carbon fibre shims come in at a super-lightweight 3.5 grams per shim, compared to weighty titanium which are a typical 17 grams per shim. \u003cstrong\u003eThat's a dramatic 79% weight saving\u003c\/strong\u003e.\u003c\/p\u003e\n\u003cp\u003eThat's not the only comparison which makes titanium inferior though: carbon fibre also has a much lower heat conduction compared to titanium (1W\/mK compared to 22W\/mK for titanium and 65W\/mK for steel). Anything that helps reduce the temperature and increase efficiency of brake components is a good thing, especially as caliper seals are at risk of being damaged when they get too hot.\u003c\/p\u003e\n\u003cp\u003eInstalling these carbon fibre brake pad shims will certainly inspire confidence that when you brake aggressively, all the components are being kept cool and working at their best.\u003c\/p\u003e\n\u003cp\u003eYou can also re-use the shims when changing pads, as long as they're in a good condition.\u003c\/p\u003e\n\u003ctable\u003e\n \u003ccaption\u003eCaliper Temperatures\u003c\/caption\u003e\n \u003cthead\u003e\n \u003ctr\u003e\n \u003ctd\u003e\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003eStandard\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003eHEL Carbon Fibre Shims\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003eDifference\u003c\/b\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003c\/thead\u003e\n \u003ctbody\u003e\n \u003ctr\u003e\n \u003ctd\u003eFront Right\u003c\/td\u003e\n \u003ctd\u003e217.8°C\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003e165.6°C\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd style=\"color:#468c1e\"\u003e\u003cb\u003e↓  52.2°C (24%)\u003c\/b\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eFront Left\u003c\/td\u003e\n \u003ctd\u003e224.8°C\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003e178.9°C\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd style=\"color:#468c1e\"\u003e\u003cb\u003e↓  45.9°C (20.4%)\u003c\/b\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eRear Right\u003c\/td\u003e\n \u003ctd\u003e138.9°C\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003e116.6°C\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd style=\"color:#468c1e\"\u003e\u003cb\u003e↓  22.3°C (16.1%)\u003c\/b\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003ctr\u003e\n \u003ctd\u003eRear Left\u003c\/td\u003e\n \u003ctd\u003e131.1°C\u003c\/td\u003e\n \u003ctd\u003e\u003cb\u003e113.3°C\u003c\/b\u003e\u003c\/td\u003e\n \u003ctd style=\"color:#468c1e\"\u003e\u003cb\u003e↓  17.8°C (13.6%)\u003c\/b\u003e\u003c\/td\u003e\n \u003c\/tr\u003e\n \u003c\/tbody\u003e\n\u003c\/table\u003e","vendor":"HEL","product_type":"Brake Pad Shims","created_at":"2026-10-28T22:44:07+00:00","handle":"hel-carbon-fibre-brake-pad-shims-for-ap-racing-cp5070-d51-calipers-hcfs-4-006","updated_at":"2026-11-02T23:44:55+00:00","published_at":"2026-11-01T14:16:13+00:00","template_suffix":null,"published_scope":"global","tags":"brand:hel, cat:braking, class:equipment-service-non-vehicle, dept:performance-parts, type:brake-pad-shim","variants":[{"id":56372928971094,"product_id":11424187416918,"title":"Fronts (4 Shims)","price":"132.29","sku":"HCFS-4-006","position":1,"compare_at_price":"","fulfillment_service":"manual","inventory_management":null,"option1":"Fronts (4 Shims)","option2":null,"option3":null,"created_at":"2026-10-28T22:44:07+00:00","updated_at":"2026-11-02T23:44:55+00:00","taxable":true,"barcode":null,"grams":0,"image_id":null,"weight":0.0,"weight_unit":"kg","requires_shipping":true,"quantity_rule":{"min":1,"max":null,"increment":1},"price_currency":"GBP","compare_at_price_currency":"","quantity_price_breaks":[]}],"options":[{"id":14615881122134,"product_id":11424187416918,"name":"Kit","position":1,"values":["Fronts (4 Shims)"]}],"images":[{"id":87067905917270,"product_id":11424187416918,"position":1,"created_at":"2026-10-28T22:44:07+00:00","updated_at":"2026-10-28T22:44:09+00:00","alt":"Carbon Fibre Brake Pad Shims for AP Racing CP5070 D51 calipers","width":1600,"height":1600,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0952\/1849\/9926\/files\/hcfs-4_1_08e51b11-849c-4930-aa11-017127d574fc.jpg?v=1793227449","variant_ids":[]}],"image":{"id":87067905917270,"product_id":11424187416918,"position":1,"created_at":"2026-10-28T22:44:07+00:00","updated_at":"2026-10-28T22:44:09+00:00","alt":"Carbon Fibre Brake Pad Shims for AP Racing CP5070 D51 calipers","width":1600,"height":1600,"src":"https:\/\/cdn.shopify.com\/s\/files\/1\/0952\/1849\/9926\/files\/hcfs-4_1_08e51b11-849c-4930-aa11-017127d574fc.jpg?v=1793227449","variant_ids":[]}}}
