Fitment Notes

• Subaru WRX fitment is for the WRX STI only - the standard WRX (non-STI) VA uses a different, smaller front caliper and is not compatible with DB1845SP. Do not fit to the standard WRX front caliper.
• Ford Mustang fitment is for the Shelby GT500 only - the GT500 uses a Brembo 6-piston front caliper with a larger pad shape than the standard GT or Boss 302. The DB1845SP will not fit standard Mustang GT or Performance Pack Brembo calipers.
• Ford Falcon fitment applies to BF and FG XR6T (turbocharged) variants equipped with the upgraded Brembo front caliper. Naturally aspirated Falcon XR6/XR8 and base model Falcons use a different front pad fitment.
• All fitments share the Brembo large-format 6-piston front caliper configuration and D1303 pad shape. DBA recommends comparing existing pad dimensions against the DB1845SP pad shape diagram before ordering to confirm compatibility.
• Recommended rotor pairing: DBA Street Series T2 slotted or 4000 Series T3 slotted front rotors for optimum braking performance and shortened system bed-in time.

Features

• Semi-metallic carbon fibre friction compound delivers a meaningful step up in initial bite, pedal response, and thermal consistency over OEM replacement pads - the right profile for a daily-driven or weekend-performance vehicle equipped with a Brembo 6-piston front caliper, where improved braking without the cold-bite penalty of a full track compound is the goal.
• Copper-free, NSFI certified formulation reduces the environmental impact of brake dust on waterways and marine life without compromising the friction output required on high-performance platforms like the IS F, WRX STI, GT500, and Giulia Quadrifoglio.
• Optimal braking consistency maintained up to 500°C (932°F) - sufficient thermal headroom for spirited street driving, canyon runs, and light autocross events, while retaining the drivability and low noise expected from a vehicle used as a daily driver.
• Factory post-curing (scorching/TSP) process applied during manufacturing raises cold friction effectiveness from the first brake application and significantly shortens the bedding-in period compared to uncured pads - practical for vehicles that may not get a formal, gradual bed-in run.
• Application-specific slots machined into the friction face continuously vent heat and expel friction gases and dust during braking, maintaining consistent bite throughout a drive and preventing glazing during sustained spirited use.
• Application-specific multi-layered elastomeric coated NVH shims are included, reducing brake squeal and pedal vibration - critical on platforms like the IS F, Giulia Quadrifoglio, and Ghibli where brake noise would be particularly noticeable given the overall refinement of these vehicles.
• Direct OE-replacement bolt-on fit - no modification to the factory Brembo caliper, bracket, or hardware required on any listed vehicle.
• Engineered as the optimal match for DBA's Street Series T2 or 4000 Series T3 slotted front rotors to form a matched system with improved first-application bite and a shortened overall bed-in period.

Product Description

The DBA DB1845SP Street Performance front brake pads are purpose-fitted for a group of high-performance and performance-luxury vehicles that share the Brembo large-format 6-piston front caliper and D1303 pad shape - covering the Lexus IS F (2008-2012), Ford Mustang Shelby GT500 (2013), Subaru WRX STI VA (2015-2021), Ford Falcon XR6T in BF and FG form (2005-2014), the Alfa Romeo Giulia Quadrifoglio (2018-2023), and the Maserati Ghibli M157 (2014-2018). Despite being diverse platforms in character and market positioning, all of these vehicles were specified from the factory with a Brembo 6-piston front caliper that demands a pad with this specific shape and backing plate - and all benefit from the same improvement: a step up in initial bite, thermal headroom, and pedal consistency over the OEM compound without sacrificing daily drivability.

The DB1845SP is built around DBA's semi-metallic carbon fibre compound in a copper-free, NSFI-certified formulation, and is rated to 500°C (932°F). This positions it squarely in the performance street range - noticeably more capable than OEM replacements under sustained spirited driving, canyon running, or occasional autocross use, but without the cold-bite severity, elevated noise, or short service life of a full track compound. Two fitment notes buyers must check: for Subaru owners, this pad fits the WRX STI only - the standard WRX VA has a smaller, different-pattern front caliper that is incompatible. For Ford Mustang owners, this fits the Shelby GT500 only - the GT500's Brembo 6-pot uses a larger pad shape than the standard Mustang GT and Performance Pack Brembo calipers.

The factory post-curing process shortens the bedding-in period considerably, which matters on daily-driven performance vehicles that may not be run through a formal graduated bed-in routine. Application-specific NVH shims ensure the front brakes remain quiet and vibration-free across the full range of operating temperatures these vehicles encounter in daily use - particularly important on the IS F, Giulia Quadrifoglio, and Ghibli, where brake noise would be conspicuous against the overall refinement of the platform. DBA recommends pairing the DB1845SP with Street Series T2 slotted or 4000 Series T3 slotted front rotors for a matched system with improved initial bite and a shorter overall brake system break-in period.
