Brembo Big Brake Kits for Mazda Mazda3 (2019-2026)

This page lists the Brembo big brake kits we offer for the Mazda3 from 2019 on. There are two front kits, both GT 4-piston kits on 345x28mm 2-piece discs, in the P and S caliper families. The current Mazda3, especially the 2.5 Turbo, is quick enough that a bigger front brake gives a noticeably firmer pedal and more fade resistance. 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 both kits for the Mazda3 sedan and hatchback from 2019. The P caliper kit comes in black, red, silver, yellow, GT-S or GT-R. The S caliper kit comes in black, red, yellow or fluorescent yellow. Both offer drilled, Type 1 Slotted or Type 3 Slotted discs.

Choosing Your Kit

• Kit: Two front kits are listed first: a GT 4-piston kit on 345x28mm discs (P caliper family) and a GT 4-piston kit on 345x28mm discs (S caliper family). Each kit name gives the axle, the system (GT or PISTA), the piston count and the disc size.
• Finish: front GT 4-piston 345x28mm kit (P caliper): black, red, silver, yellow, GT-S (black hard-anodized), and GT-R (billet-machined and nickel-plated); front GT 4-piston 345x28mm kit (S caliper): black, red, yellow, and fluorescent yellow. 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.

FAQ

What is the difference between the P and S caliper kits?
Both are 4-piston GT calipers on 345x28mm 2-piece discs. They differ in finish choices: the P caliper offers silver, GT-S and GT-R, and the S caliper offers fluorescent yellow.

Does this fit the Mazda3 Turbo and AWD?
Brembo lists these kits for the 2019-on Mazda3 without splitting by engine or drivetrain. Send us your details if you want us to confirm.

Is there a rear kit?
Brembo lists front kits only for this Mazda3.

Will these kits fit my wheels?
Every big brake kit needs wheel clearance, and the 345mm kits need the most room on the Mazda3. Send us your wheel size and offset and we will check them against Brembo's clearance data before you order.

Fitment Notes

Brembo lists both kits on this page for the Mazda3 from 2019 on. 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.

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