This is a direct replacement that reuses your factory G60\/G61 calipers.

The i5 is a heavy, high-torque EV, and iron rotors on this platform shed a lot of dark dust onto the wheels.

Confirm your trim and rotor size before ordering—fitment is limited to the M135i sizes listed here.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do these behave in winter and on cold first stops?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003ePhysics first: any cold carbon-ceramic disc bites a little less than cold iron until it warms, which is normal and not a defect.

It fits only the M3 trims and rotor sizes listed on this page.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do these behave in winter and on a cold first stop?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003ePhysics first: an untuned cold carbon-ceramic disc bites less than cold iron until it warms.

It only fits the M5 trim listed on this page with those exact rotor diameters, so if your car has been modified with non-standard calipers or rotors, confirm before ordering.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eThe M5 never came with ceramics from BMW — is this a real bolt-on or a hack?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eIt's engineered as a direct replacement. Because BMW never offered CCBs on the E60\/E61 M5, there is no factory ceramic part to buy; this kit recreates the fitment. The carbon-ceramic rotors are machined to the 374mm front and 370mm rear factory dimensions, mounted on billet hats with floating hardware that indexes to your existing hubs and calipers. Nothing is cut or fabricated on the car — pads, rotors, hats, and hardware are all supplied to match the stock caliper geometry.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do these behave in winter or on a cold start?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eStraight physics: a cold carbon-ceramic disc bites a little less than cold iron on the first stop or two.

The 1,800kg-plus M5 loads its front brakes hard, and stock iron rotors on the S85 commonly go spongy after a couple of hard laps. The carbon-ceramic rotors here run far higher thermal capacity and won't glaze the way iron does. The matched pads use a low-metallic resin-composite compound with steel, copper, and aramid fiber, average friction around 0.44, and heat resistance to about 750°C with strong anti-fade behavior. The unsprung and rotating weight drop also helps the front end turn in more willingly.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"StopFlex","offers":[{"title":"Default Title","offer_id":47895403921667,"sku":"100057","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/8933\/5811\/files\/BMW-M5-E60-CCB-Brake_22703ee0-bccd-42f1-baee-5349f5c3a833.jpg?v=1784007509"},{"product_id":"bmw-m5-f10-carbon-ceramic-brake-kits","title":"2012-2016 BMW M5 (F10) Carbon Ceramic Brake Rotors","description":"\u003cdiv class=\"sfx\"\u003e\n\u003csection class=\"box\" id=\"sfx-cases\" hidden\u003e\u003ch2\u003eReal Customer Builds \u0026amp; Reviews\u003c\/h2\u003e\n\u003cdiv class=\"cases\" id=\"sfx-cases-row\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"cta-row\"\u003e\u003ca class=\"btn ghost\" href=\"https:\/\/stopflex-ccb.com\/blogs\/carbon-ceramic-brakes-reviews\"\u003eView All\u003c\/a\u003e\u003c\/div\u003e\n\u003cscript\u003e(function(){var brand=\"BMW\",blogPath=\"\/blogs\/carbon-ceramic-brakes-reviews\";function escT(t){var d=document.createElement('div');d.textContent=t||'';return d.innerHTML;}function render(list){if(!list.length)return;var row=document.getElementById('sfx-cases-row');var out='';list.slice(0,8).forEach(function(a){if(!a.image)return;out+='\u003cdiv class=\"card\"\u003e\u003ca href=\"'+a.url+'\"\u003e\u003cimg src=\"'+a.image+'\" alt=\"'+escT(a.title)+'\" loading=\"lazy\"\u003e\u003c\/a\u003e'+'\u003ch4\u003e\u003ca href=\"'+a.url+'\"\u003e'+escT(a.title)+'\u003c\/a\u003e\u003c\/h4\u003e\u003c\/div\u003e';});if(!out)return;row.innerHTML=out;document.getElementById('sfx-cases').hidden=false;}function search(q,cb){fetch('\/search\/suggest.json?q='+encodeURIComponent(q)+'\u0026resources[type]=article\u0026resources[limit]=10').then(function(r){return r.json();}).then(function(d){var arts=((d.resources||{}).results||{}).articles||[];cb(arts.filter(function(a){return a.url.indexOf(blogPath)!==-1;}));}).catch(function(){cb([]);});}search(brand,function(same){if(same.length){render(same);}else{search('carbon ceramic',function(other){render(other);});}});})();\u003c\/script\u003e\u003c\/section\u003e\u003csection class=\"box red\"\u003e\u003ch2\u003eWill This Fit My Car?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDirect Replacement CCB Discs (Retain Factory Calipers)\u003c\/strong\u003e for the 2012-2016 BMW M5 (F10).

This kit is a direct replacement for the E63\/E64 M6 running the factory 374mm front and 370mm rear rotor sizes. It reuses your existing factory calipers, so no bracket relocation or master-cylinder change is needed. This car's front calipers are 4-piston fixed units, which is the minimum required for direct-replacement carbon-ceramic discs, so you're covered. Confirm your rotor diameters before ordering, since compatibility is limited to the sizes listed here.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do these behave in winter and on the first cold stops?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eHonest answer: an untuned cold carbon-ceramic disc bites a little less than cold iron on the very first stops. That's normal physics, not a fault. We addressed it two ways on this kit — the low-metallic resin-composite pad compound and the disc's ceramic coating are both optimized for cold starts, so cold-car braking feel now comes very close to warm-car feel. On the coldest mornings, leave a little extra following distance for the first one or two stops, then the system is at full strength.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWill these solve the fade I get after a lap or two at the track?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eThat's the main reason M6 owners switch. The V10 E63\/E64 is heavy and fast, and the factory iron rotors soak up heat quickly on track and go spongy. Carbon-ceramic discs run far higher thermal capacity and shed heat without the fade curve iron shows. The matched pad resists fade to about 750°C with a steady average friction coefficient near 0.44, so pedal feel stays consistent lap after lap on the same 374mm front footprint.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat do I gain over buying new factory iron rotors?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eBeyond fade resistance, you drop significant unsprung and rotational weight at each corner on a car that already carries a lot of mass up front, which sharpens turn-in and ride quality.

Verify your fronts are the factory X5 M units before ordering; standard X5 hardware is not covered by this page.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eHow do these brakes behave in winter on a cold start?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eStraight physics: any cold carbon-ceramic disc bites a little less than cold iron on the first stops.

On the coldest mornings, leave a little extra following distance for the first few stops until the front 395mm rotors come up to temperature, then they settle into full bite.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhy is BMW quoting so much for X5 M front brakes, and is this a better spend?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eThe X5 M's 395mm front and 385mm rear setup uses large, expensive components, so factory replacement quotes climb fast.

If you plan to keep the F95 and drive it hard, the long service life and near-zero dust change the total-cost picture over time.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\n\u003c\/div\u003e\u003c\/section\u003e\n\u003c\/div\u003e","brand":"StopFlex","offers":[{"title":"Default Title","offer_id":47895408410883,"sku":"100078","price":3000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0761\/8933\/5811\/files\/BMW-X5M-F95-CCB-Brake_2105b8aa-6b9e-46ee-becb-1a5497e29580.jpg?v=1784007526"},{"product_id":"bmw-x6-m60i-m50i-m50d-g06-carbon-ceramic-brake-kits","title":"2020-2026+ BMW X6 M50i \/ M50d \/ M60i (G06) Carbon Ceramic Brake Rotors","description":"\u003cdiv class=\"sfx\"\u003e\n\u003csection class=\"box\" id=\"sfx-cases\" hidden\u003e\u003ch2\u003eReal Customer Builds \u0026amp; Reviews\u003c\/h2\u003e\n\u003cdiv class=\"cases\" id=\"sfx-cases-row\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"cta-row\"\u003e\u003ca class=\"btn ghost\" href=\"https:\/\/stopflex-ccb.com\/blogs\/carbon-ceramic-brakes-reviews\"\u003eView All\u003c\/a\u003e\u003c\/div\u003e\n\u003cscript\u003e(function(){var brand=\"BMW\",blogPath=\"\/blogs\/carbon-ceramic-brakes-reviews\";function escT(t){var d=document.createElement('div');d.textContent=t||'';return d.innerHTML;}function render(list){if(!list.length)return;var row=document.getElementById('sfx-cases-row');var out='';list.slice(0,8).forEach(function(a){if(!a.image)return;out+='\u003cdiv class=\"card\"\u003e\u003ca href=\"'+a.url+'\"\u003e\u003cimg src=\"'+a.image+'\" alt=\"'+escT(a.title)+'\" loading=\"lazy\"\u003e\u003c\/a\u003e'+'\u003ch4\u003e\u003ca href=\"'+a.url+'\"\u003e'+escT(a.title)+'\u003c\/a\u003e\u003c\/h4\u003e\u003c\/div\u003e';});if(!out)return;row.innerHTML=out;document.getElementById('sfx-cases').hidden=false;}function search(q,cb){fetch('\/search\/suggest.json?q='+encodeURIComponent(q)+'\u0026resources[type]=article\u0026resources[limit]=10').then(function(r){return r.json();}).then(function(d){var arts=((d.resources||{}).results||{}).articles||[];cb(arts.filter(function(a){return a.url.indexOf(blogPath)!==-1;}));}).catch(function(){cb([]);});}search(brand,function(same){if(same.length){render(same);}else{search('carbon ceramic',function(other){render(other);});}});})();\u003c\/script\u003e\u003c\/section\u003e\u003csection class=\"box red\"\u003e\u003ch2\u003eWill This Fit My Car?\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDirect Replacement CCB Discs (Retain Factory Calipers)\u003c\/strong\u003e for the 2020-2026+ BMW X6 M50i \/ M50d \/ M60i (G06).

StopFlex tunes both the low-metallic resin-composite pad and the disc's ceramic coating for cold starts, so first-stop feel on a cold F86 is now very close to summer feel.

Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.\u003c\/p\u003e\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"cta\"\u003e\u003ch2\u003eGet Your Fitment Confirmed\u003c\/h2\u003e\n\u003cp\u003eShare your year, model, trim, wheel size, current rotor dimensions, and caliper type — every order is verified against your VIN-level configuration before it goes to production.\u003c\/p\u003e\n\u003cdiv class=\"cta-row\"\u003e\n\u003ca class=\"btn\" href=\"\/pages\/carbon-ceramic-brakes\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eCarbon Ceramic Brakes: Buying \u0026amp; Fitment Guide\u003c\/a\u003e\u003ca class=\"btn ghost\" href=\"#contact_form_page\"\u003eConfirm Fitment\u003c\/a\u003e\n\u003c\/div\u003e\u003c\/section\u003e\u003csection class=\"box\"\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n\u003cdetails\u003e\u003csummary\u003eWill this fit my exact F20\/F21 trim, like an M140i versus a 118i?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eEvery kit is engineered for the specific trim you confirm, not the platform. The M135i and M140i use different front knuckles, hub geometry, and wheel clearance than the 116i\/118i\/120i models, so the brackets, caliper mounting, and rotor-hat offsets we build are matched to your car. We never ship a generic F20\/F21 bolt-on and hope it clears.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat wheel size do I need to clear the 380 mm front rotor?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eThe 380 mm front rotor and 6-piston caliper require a minimum 19-inch wheel.

That is physics, not a fault. We've optimized both the pad compound and the disc's ceramic coating for cold starts, so a cold-car winter pedal now feels very close to a warm summer one. Leave a little extra following distance on your first stops of the day and you're set.\u003c\/p\u003e\u003c\/div\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eDoes the kit keep the factory electronic parking brake working?\u003c\/summary\u003e\u003cdiv class=\"a\"\u003e\u003cp\u003eYes. The F20\/F21 uses a factory electronic parking brake, and the rear caliper and hat setup we build retains full EPB function.
