DBA 5000 Series Front Rotor Options + 4000 Series Rear Rotors
For 6th Gen. Camaro ZL1 + 1LE Package (2017–2024)
Why You Need This Upgrade…
The factory ZL1 braking system is very capable for the street and mild tracking, but once you increase power, and push the car harder at the track, the limitations begin to show. Heat builds quickly, consistency drops off, and the pedal feel you rely on starts to change when you need it most. Brake performance isn’t just about bite, it’s about consistency.
This DBA rotor setup is designed to improve thermal stability, maintain consistent braking performance under heavy use, and give you confidence whether you’re driving aggressively on the street or pushing the car on track. Incredibly, they seem to be able to provide amazing results, for a fraction of a full blown race kit. This is why DBA rotors are considered second to none for their value ratio.
This DBA setup gives you:
A true 2-piece front rotor solution where heat matters most
Flexible upgrade paths depending on your goals and budget
A proven rear rotor upgrade that complements the system
Rather than forcing a one-size-fits-all solution, this allows you to build the system that fits your driving style.
Front Rotor Options — Understanding Your Choices…
Option 1: Complete DBA 2-Piece Assembly - DBA53940BLKS (Aluminum Hat + T3 Ring)
This is the full DBA engineered solution.
Lightweight aluminum hat reduces heat transfer into the hub
Floating 2-piece design improves thermal expansion control
Pre-assembled and ready to install
Optimized as a complete system by DBA
This is the best option for customers who want a complete, performance-focused upgrade with no compromises.
Option 2: Replacement Rings for DBA Hats - DBA53940.1S
For customers already running DBA hats, these rings allow you to service your rotors without replacing the entire assembly.
Direct replacement for DBA 5000 series hats
Maintains full 2-piece system benefits
Reduces long-term ownership cost
This is where the 5000 series shines—serviceability and long-term value.
Option 3: Replacement Rings for OEM Hats - DBA53916.1S
For customers who want to retain the factory ZL1 hat and hardware.
Designed to mount to OEM hat assemblies
Lower cost entry into high-performance rotor rings
Retains factory fitment and hardware
This is an excellent option for those looking to improve braking performance without committing to a full 2-piece conversion.
OEM Hat vs DBA Hat — Which Should You Choose?
Why Keep the OEM Hat
Why Upgrade to the DBA Hat
Better heat isolation from the hub and bearings
Reduced risk of rotor distortion under repeated load
Designed specifically for high-performance and track use
Faster Installation
Why the Front Rotor Upgrades Matter Most…
The front brakes handle the majority of braking force and heat.
Upgrading the front rotors:
This is where you get the biggest performance gain.
Rear Rotor Solution — DBA 4000 Series - DBA42605S
The rear braking system plays a supporting role, which is why we offer the matching DBA slotted one-piece rotors to match.
The DBA 4000 Series rear rotor provides:
High carbon cast iron construction
Improved heat dissipation over OEM
T3 slot design for consistent pad engagement
Direct replacement simplicity
This keeps the system balanced without adding unnecessary cost or complexity.
T3 Slot Technology…
DBA’s T3 slot design is engineered for performance and consistency.
Tri-symmetrical slot pattern
Continuous slot engagement across the rotor surface
Reduces pad glazing
Improves initial bite and pedal feel
This results in more predictable braking under all conditions.
DBA vs Girodisc — Honest Comparison…
Both DBA and Girodisc offer high-quality solutions, and each has its strengths.
DBA advantages:
Strong performance-to-cost ratio
Proven durability and better heat management
Flexible upgrade paths (OEM hat or full 2-piece)
Lower cost of entry and maintenance
Girodisc advantages:
The difference comes down to priorities.
DBA provides excellent performance, flexibility, and value.
Girodisc offers a more premium, lightweight solution for those aiming for weight reduction.
Why We Only Offer Slotted Rotors…
This setup uses T3 slotted rotors for a reason.
Drilled rotors are more prone to cracking under repeated heat cycles. Slotted rotors provide better durability, improved pad performance, and more consistent results in real performance driving.
About DBA…
Disc Brakes Australia (DBA) has built its reputation over decades by focusing on one thing: making brake rotors that perform consistently under real-world conditions. Founded in Australia—a market known for demanding durability across extreme heat, heavy loads, and harsh driving environments—DBA developed its products around the need for reliability first, not just appearance or marketing claims. Over time, that focus has led to proprietary metallurgy, advanced cooling vane designs, and innovations like their T3 slot technology, all engineered to improve heat management and braking consistency. Today, DBA supplies rotors for everything from daily drivers to high-performance and motorsports applications worldwide. That track record of continuous engineering, combined with proven performance in demanding environments, is what gives customers confidence that they’re investing in a product designed to perform when it matters most.
