Brembo Big Brake Kits for Lexus GS (1993-2004)

This page lists the Brembo big brake kits we offer for the 1993-2004 Lexus GS300, GS400 and GS430. There are two front kits: a GT 4-piston kit on 332x32mm discs and a GT 4-piston kit on 355x32mm discs. The GS is a heavy, rear-drive sport sedan, and the V8 GS400 and GS430 in particular benefit from a bigger front brake. 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 GS300, GS400 and GS430. Both come in black, red or silver. The 332mm kit has drilled or Type 1 Slotted discs. The 355mm kit has drilled or Type 3 Slotted discs and adds thermal capacity.

Choosing Your Kit

• Kit: Two front kits are listed first: a GT 4-piston kit on 332x32mm discs and a GT 4-piston kit on 355x32mm 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, and silver. A finish that a kit does not offer cannot be selected for it.

Offered as follows: Drilled and Type 1 Slotted on the front GT 4-piston 332x32mm kit; Drilled and Type 3 Slotted on the front GT 4-piston 355x32mm kit.

FAQ

332mm or 355mm kit?
The 332mm kit fits more wheels and suits street driving. The 355mm kit adds capacity for spirited driving and track use but needs larger wheels.

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

Do these fit all three engines?
Yes. Brembo lists both kits for the GS300, GS400 and GS430.

Will these kits fit my wheels?
Every big brake kit needs wheel clearance, and the 355mm kits need the most room on the GS. 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 1993-2004 Lexus GS300, GS400 and GS430. 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.
