Which kits use the Alcon Replacement Rear Rotor for BMW F8X?

The Alcon Replacement Rear Rotor for BMW F8X is the left side rear rotor from the Alcon rear big brake kit for the BMW F8X. It is a direct replacement for the rotor supplied in the kit. If your car runs an earlier Alcon kit, send BA the kit part number and we will confirm the match before ordering.

Should I replace both sides at once?

Yes, in most cases. Rotors on the same axle wear together, and replacing one side leaves a thickness and friction difference across the axle that can pull the car under braking. Order this left side rotor with the matching right side rotor and fit new pads at the same time.

When does a rotor need replacing?

Replace a rotor when it reaches the minimum thickness in your Alcon kit documentation, or sooner if it shows cracks running from the edge, heavy scoring or heat damage. Track use wears rotors much faster than road driving, so measure them between events rather than waiting for a change in pedal feel.

Do I need new pads with a new rotor?

It is good practice. Worn pads have bedded to the old rotor surface, and fitting fresh pads lets the new rotor and pads bed in together for an even transfer layer. Follow a full bedding procedure before hard driving, and BA can quote replacement pads for the kit at the same time.

Why does the kit use a larger rotor than stock?

Alcon notes that larger rotors increase brake torque and thermal capacity, reducing the potential for brake fade. A larger rotor gives the caliper a longer lever arm and gives the heat of repeated stops more iron to soak into, which is what keeps the pedal consistent through a hard session on track.

Description

Alcon Replacement Rear Rotor for BMW F8X Alcon Big Brake Kit (Left)

The Alcon Replacement Rear Rotor for BMW F8X is the left side rear rotor assembly, 380 x 32 mm, used in the Alcon rear big brake kit for the BMW F8X, sold on its own. Alcon supplies it as a replacement rotor for its brake kits, for owners who have worn a rotor to its limit at the track or need to replace one after damage. Larger rotors increase brake torque and thermal capacity and reduce the potential for brake fade, which is the reason the kit runs a rotor this size, and a replacement keeps that capacity intact.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
