Brembo Big Brake Kits for Audi B6 A4 (2002-2005)

This page lists every Brembo big brake kit we offer for the Audi A4 (B6), sold in the US for the 2002-2005 model years. Both kits are front kits on 355x32mm two-piece discs: a GT 4-piston kit and a GT 6-piston kit. The B6 A4 came with a 1.8T four-cylinder or a 3.0L V6, and a larger front brake gives a tuned or track-driven car more consistent stops. 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.

The 355mm GT 4-piston kit comes in black, red or silver, with drilled or Type 3 slotted discs. The GT 6-piston kit on 355x32mm discs comes in black, red, silver, yellow, GT-S hard-anodized black or GT-R nickel-plated billet, with drilled or Type 3 slotted discs.

Choosing Your Kit

• Kit: Two front kits are listed first: a GT 4-piston kit on 355x32mm discs and a GT 6-piston kit on 355x32mm discs. Each kit name gives the axle, the system (GT or PISTA), the piston count and the disc size.
• Finish: front GT 4-piston 355x32mm kit: black, red, and silver; front GT 6-piston 355x32mm kit: 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 3 Slotted is aimed at regular track days. Every kit offers Drilled and Type 3 Slotted.

FAQ

Is there a rear kit for the B6 A4?
Brembo's current application list has front kits only for the Audi A4 (B6).

Which kit should I choose?
Both kits use the same 355mm disc. The GT 4-piston kit comes in black, red or silver. The GT 6-piston kit adds caliper stiffness and the yellow, GT-S and GT-R finishes.

Will these kits fit my wheels?
Every big brake kit needs wheel clearance, and the 355mm kits need the most room on the A4. 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 Audi A4 (B6) 2002-2005. 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.
