Brembo Big Brake Kits for BMW i8 I12 (2014-2020)

This page lists the Brembo big brake kit we offer for the BMW i8 coupe (I12), sold in the US for the 2014-2020 model years (BMW did not sell a 2018 model-year i8 in the US). BMW USA lists the i8 as a 2014-2020 legacy model, and production ended in June 2020. The i8 is a light, carbon-tub plug-in hybrid with a 1.5-liter turbo three-cylinder driving the rear wheels and an electric motor driving the fronts, and it is fast enough to heat the factory brakes on a canyon road or track day. A Brembo GT kit adds heat capacity and a firmer, more consistent pedal. A Brembo system replaces the caliper and disc on the axle you choose with a matched caliper, disc and pad package, sold as a complete axle set.

Brembo lists one front kit: a GT 6-piston caliper on 380x32mm two-piece discs, offered with drilled, Type 1 slotted or Type 3 slotted discs. It comes in black, red, silver or yellow, as a GT-S (black hard-anodized) or as a GT-R (billet-machined and nickel-plated).

Choosing Your Kit

• Kit: One front kit is listed first: a GT 6-piston kit on 380x32mm discs. Each kit name gives the axle, the system (GT or PISTA), the piston count and the disc size.
• Finish: every kit on this page comes in black, red, silver, yellow, GT-S (black hard-anodized), and GT-R (billet-machined and nickel-plated). A finish that a kit does not offer cannot be selected for it.
• Disc Type: drilled discs suit street driving and give good wet-weather bite; Type 1 Slotted is a street and occasional-track disc; Type 3 Slotted is aimed at regular track days. Every kit offers Drilled, Type 1 Slotted, and Type 3 Slotted.

Features

• 6-piston Brembo calipers, matched to 380x32mm discs on this car
• 2-piece disc construction: an iron friction ring on a lighter aluminum bell
• GT caliper finishes plus GT-S (black, hard-anodized) and GT-R (billet-machined, nickel-plated) on the kits that list them
• Every kit is a complete axle set

What's Included

• GT, GT-S and GT-R kits, in Brembo's words: calipers, pads, discs, brackets, hoses and hardware.

FAQ

Does this fit the i8 Roadster?
Brembo lists this kit for the i8 coupe (I12) only. The 2019-2020 i8 Roadster (I15) is not on the listing, so ask us before ordering for a Roadster.

Which disc should I choose?
Drilled discs are the classic look and suit street driving. Type 1 and Type 3 slotted discs keep the pad surface clean under heavy use and are the better choice for track days. All three are the same 380x32mm two-piece size and price.

What is the difference between GT, GT-S and GT-R?
All three are 6-piston calipers on the same disc. GT is the painted caliper, GT-S adds a black hard-anodized finish, and GT-R is machined from billet and nickel-plated.

Is there a rear kit?
No. Brembo lists only a front kit for the i8.

Will these kits fit my wheels?
Every big brake kit needs wheel clearance, and the 380mm kits need the most room on the i8. Send us your wheel size and offset and we will check them against Brembo's clearance data before you order.

Fitment Notes

Brembo lists the kit on this page for the BMW i8 coupe (I12), 2014-2020 US model years. Brembo GT systems are designed for cars at original ride height. Raising the ride height is not compatible with the brake lines included in these systems. The GT-R 6-piston caliper needs different wheel clearance from the GT 6-piston caliper.

Each kit fits the vehicles listed below. Confirm wheel clearance before ordering.
