The DBA 4000 Series Front Slotted Rotor (DBA4418S) is a direct-replacement performance brake rotor engineered specifically for the 2001–2007 Mitsubishi Lancer Evolution 7, 8, and 9. Built by Disc Brakes Australia — one of the most respected names in performance braking — the 4000 Series T3 rotor brings track-proven technology to your street or competition Evo without requiring any modifications. Whether you're pushing your Evo hard on a back road, hitting an autocross course, or simply want a more capable front rotor than stock, the DBA4418S delivers a meaningful upgrade backed by real engineering.
Key Features & Benefits
- High Carbon & Heat-Treated Iron Construction: DBA's 4000 Series T3 rotors are manufactured using high carbon, heat-treated iron — the same material specification used in demanding motorsport applications. This composition resists heat-induced cracking and warping under repeated hard stops, giving Evo owners confidence during spirited driving or track days.
- Patented Kangaroo Paw Ventilation: DBA's proprietary Kangaroo Paw vane design optimizes internal airflow through the rotor, improving heat dissipation compared to standard straight-vane rotors. Better cooling means more consistent brake feel lap after lap and reduced risk of brake fade.
- Tri-Symmetrical Slotting: The patented Tri-symmetrical slot pattern continuously sweeps debris, dust, and gas from the pad face, maintaining maximum pad-to-rotor contact. This keeps bite sharp and consistent and extends pad life by reducing glazing — a real advantage for an all-wheel-drive performance car that sees hard use.
- Direct OEM Replacement Fit: The DBA4418S is designed as a drop-in replacement for the factory front rotors on Evo 7, 8, and 9 platforms. No bracket modifications, adapter plates, or caliper changes are required — bolt on and drive.
- Street & Track Versatility: The 4000 Series sits in DBA's performance tier, making it well-suited for enthusiasts who want more than a stock rotor but still need a rotor that works effectively from a cold start on a daily driver.

Note: This rotor covers the Evo 7/8/9 generation (CT9A chassis). It is not a fit for the Lancer Evolution X (2008–2015), which uses a different front rotor specification — see the DBA42225S for Evo X rear applications. If you are unsure whether this part fits your exact build or trim, use the fitment checker on this page or contact the ThreePiece.us team directly before ordering.
What's in the Box
The DBA4418S ships as a single front rotor. If you are replacing both front rotors — which is standard practice for balanced braking performance — you will need to order a quantity of two. Brake pads are sold separately.

Frequently Asked Questions
Q: Does this rotor fit the Lancer Evolution X (2008+)?
A: No. The DBA4418S is designed for the Evo 7, 8, and 9 (2001–2007). The Evolution X uses a different platform and different front rotor dimensions. If you own an Evo X, please contact us so we can point you to the correct DBA part for your application.
Q: Is this a slotted-only rotor, or does it also have drilled holes?
A: The DBA4418S is a slotted-only rotor featuring DBA's Tri-symmetrical slot pattern. If you prefer a drilled and slotted combination for the same fitment, DBA also offers the DBA4418XS (03–05 Evo 8/9 specific). The slotted-only 4418S is generally preferred for track use where thermal stress from repeated braking cycles can make drilled holes a potential crack initiation point.
Q: Do I need any special tools or hardware to install the DBA4418S?
A: The DBA4418S is engineered as a direct OEM replacement, meaning it installs using the same hardware and procedure as the stock front rotor on your Evo 7/8/9. No adapter brackets or caliper modifications are required. Standard rotor replacement tools and torque specs for your vehicle apply. As with any brake service, we recommend having the work performed or inspected by a qualified technician.
Q: Do I need to order two rotors to replace both front brakes?
A: Yes. The DBA4418S is sold as a single rotor. To replace both front rotors — which is strongly recommended for even, balanced braking — add a quantity of two to your cart. Brake pads are not included and should be ordered separately.
