DBA DB2429SP Street Performance Rear Brake Pads 2016-2022 Honda Civic 2019-2022 Acura RDX SP Compound

The DB2429SP from DBA (Disc Brakes Australia) delivers Street Performance rear brake pads engineered specifically for the 2016-2022 Honda Civic and 2019-2022 Acura RDX. Built on DBA's semi-metallic carbon fibre, copper-free SP compound, the DBADB2429SP raises stopping power well beyond factory levels while keeping noise, vibration, and harshness under control for daily street use. Every set ships factory-scorched via DBA's Thermal Stability Profiling (TSP) process, so the pads arrive ready to bed in quickly with no lengthy break-in rituals. FMSI number 9106-D1878. Made in Silverwater, Sydney, Australia.

Why the DB2429SP Outperforms OEM Rear Pads

Factory Honda and Acura rear pads are formulated to the lowest common denominator: quiet, cheap to produce, and sized for warranty intervals rather than driving enjoyment. The DB2429SP replaces them with a semi-metallic carbon fibre matrix that dramatically increases friction stability from cold temperatures all the way up to 438 degrees Celsius (820 degrees Fahrenheit). That wider operating window means the pads bite consistently whether you are coasting into a parking lot or trail-braking into a highway on-ramp.

The SP compound is certified to ECE R90, the European brake pad performance standard, meaning every production batch is independently tested and verified to meet or exceed the stopping performance of the OEM pads it replaces. It is also copper-free (N class compliant), meeting the current and upcoming North American environmental regulations that restrict heavy-metal brake dust. You get better stopping performance, greener chemistry, and DBA's factory-scorched surface in a single drop-in replacement.

TSP: Thermal Stability Profiling Already Done

Most aftermarket brake pads ship in raw, unprocessed form and require a careful bedding sequence before they perform correctly. The DBADB2429SP skips that delay. DBA's Thermal Stability Profiling (TSP) process factory-scorches every pad before it leaves Silverwater, burning off surface resins and curing the friction material to a consistent, stable depth across the entire pad face. The result is a more predictable initial bite from the very first pedal application and a shorter, lower-stress bedding sequence on your vehicle. For street drivers who rotate through tires and pads on a schedule, TSP is a genuine time and safety advantage.

Slots, Chamfers, and NVH Shims

The DB2429SP backing plate includes three noise and performance features that are often omitted on entry-level pads:

• Slots: Machined slots in the friction face channel away gas, dust, and heat, keeping the pad-to-rotor interface clean under repeated stops.
• Chamfers: Bevelled leading and trailing edges reduce the initial contact stress that causes edge lift, pad taper wear, and low-speed squeal.
• NVH Shims: Application-specific anti-squeal shims are bonded directly to the backing plate. Unlike loose shims that can slip or fall during installation, these stay in position permanently and tune vibration damping for the exact caliper and knuckle geometry of the Honda Civic and Acura RDX rear corner.

The DB2429SP is designed for the ATE-type rear caliper fitted to these vehicles. Pad dimensions are 122.4 mm length, 53.5 mm / 48.5 mm height (tapered profile), and 13.9 mm thickness.

What's Included

• 4 brake pads: LH Inner, RH Inner, and 2 Outer pads (complete rear axle set)
• High-temperature brake pad lubricant (for caliper slide pins and abutment clips)
• Servicing sticker for door frame installation date reminder
• Bedding-in instruction sheet
• Application-specific anti-squeal NVH shims (integrated on backing plate, not loose)

Fitment: Honda Civic and Acura RDX Rear Brake Pads

The DB2429SP fits the rear axle of confirmed model years listed below. 

Important note for Honda Civic buyers: US fitment data has not been fully confirmed for the 2018-2021 model years on all trims. If your Civic is a 2018, 2019, 2020, or 2021, please verify fitment using your VIN directly on DBA's website at dba.com.au before ordering. European production data confirms fitment through the full 2017-2021 run, but Black Ops Auto Works lists only US-confirmed years below to protect our customers from returns. The Acura RDX uses a separate fitment group: 2019, 2021, and 2022 are confirmed; 2020 should be verified.

DBA DB2429 Compound Line: Which Pad Is Right for You?

DBA offers four compounds on the DB2429 platform, all sharing the same dimensions and fitment for the Honda Civic and Acura RDX rear axle. Choose based on how and where you drive:

For a Honda Civic Sport, Si, or Type R used on both street and occasional autocross or track days, the DB2429SP is the natural choice: it offers meaningfully higher heat resistance and friction stability than the SS ceramic, without the cold-bite and noise trade-offs of the XP compound on a daily driver.

Full Specifications

Warranty and Legal

The DB2429SP is covered by DBA's 12-month or 20,000 km (12,000 miles) limited warranty, whichever comes first, against defects in materials and workmanship. This warranty applies from the date of original purchase and is non-transferable.

Installing aftermarket brake pads will not void your Honda or Acura factory powertrain warranty. Under the federal Magnuson-Moss Warranty Act, a vehicle manufacturer cannot void your warranty simply because you installed an aftermarket part. They must prove the aftermarket component directly caused the specific failure being claimed. A set of brake pads operates in a self-contained system; they do not affect powertrain, engine, or transmission warranty coverage.

Installation Overview

Replacing rear brake pads on the Honda Civic and Acura RDX is a straightforward DIY job for anyone with basic automotive experience. The DB2429SP is a direct-fit, drop-in replacement for the factory rear pads. No machining, no modifications, and no caliper upgrades are required.

• Lift and support the rear of the vehicle on jack stands; remove rear wheels
• Compress the ATE-type rear caliper piston using a caliper wind-back tool (cube-drive, not a simple C-clamp, as rear pistons typically thread back)
• Remove the caliper carrier bolts and slide out the old pads
• Clean abutment clips and caliper sliding surfaces; apply included high-temperature lubricant to contact points only (never on friction faces)
• Install the DB2429SP pads with shims facing the caliper piston and outer pad facing the rotor
• Reinstall caliper, torque carrier bolts to spec, and pump the brake pedal before moving the vehicle
• Apply the included servicing sticker to your door frame with the installation date and mileage
• Follow the included bedding-in instructions: moderate stops from 40 mph x 6-8 repetitions, then allow brakes to cool completely before driving normally

Note: If your rotors are at or near minimum thickness, this is the correct time to replace them. DBA offers matching rotors for the Honda Civic and Acura RDX; pairing DB2429SP pads with DBA rotors delivers optimal compound-to-rotor seating and consistent performance from the first bed-in stop.

Frequently Asked Questions

Does the DB2429SP fit a 2018, 2019, 2020, or 2021 Honda Civic?
US fitment data for the 2018-2021 Honda Civic has a gap in confirmed fitment records for some trims. European production data confirms the same pad fits the full 2017-2021 Civic production run, but Black Ops Auto Works only lists US-confirmed years in the fitment table. If your Civic falls in that window, use the VIN lookup tool at dba.com.au to confirm the correct pad before ordering. Do not assume compatibility based on European data alone.

Does the DB2429SP fit the Honda Civic Type R?
Yes, fitment is confirmed for the 2017 Honda Civic Type R (FK8). The Type R uses the same ATE-type rear caliper architecture as other 10th-generation Civic trims. The 2022 Civic Type R (FL5) is not listed in the confirmed fitment table; verify via VIN at dba.com.au for that model year.

What is the difference between the DB2429SP and the DB2429SS?
The DB2429SS (Street Series) is a ceramic-style OEM-replacement compound: low dust, quiet, gentle on rotors, and suited for straightforward commuting. The DB2429SP uses a semi-metallic carbon fibre SP compound with a significantly higher maximum operating temperature (438 degrees C vs. lower for the SS), better friction stability under repeated hard stops, and ECE R90 certification. The SP compound is the correct choice for Sport, Si, and Type R trims, or any driver who values confident brake feel over minimising brake dust.

Are the DB2429SP pads compatible with the 2019-2022 Acura RDX?
Yes. The 2019 Acura RDX (Base and SH-AWD), and 2021-2022 RDX (Base, PMC Edition, and SH-AWD) are confirmed fitments. The 2020 Acura RDX should be verified via VIN before ordering. All confirmed RDX fitments use the ATE-type rear caliper that the DB2429SP is designed for.

Will the DB2429SP void my Honda or Acura factory warranty?
No. Under the federal Magnuson-Moss Warranty Act, a vehicle manufacturer cannot void your factory warranty because you installed an aftermarket part. Honda or Acura would need to prove that the DB2429SP directly caused the specific failure being claimed, which does not apply to powertrain, engine, or drivetrain warranty coverage. Brake pads are considered a wear item, and replacing them with aftermarket pads is standard practice at independent shops nationwide.

Do I need to bed in the DB2429SP before driving normally?
Yes, but the process is shorter than with untreated pads. DBA's TSP factory-scorching has already done the initial resin burn-off. The bedding procedure included in the box typically calls for 6-8 moderate stops from 40 mph with cooling time between sequences. Avoid panic-stop or track use until the bed-in is complete. Full bedding-in instructions are included in the box.

What is the maximum temperature rating for the DB2429SP?
The SP compound is rated to 438 degrees Celsius (820 degrees Fahrenheit). For comparison, most OEM street pads are rated in the 300-350 degrees C range. The DB2429SP's higher ceiling means the compound remains stable and consistent during aggressive street driving, repeated downhill braking, and occasional track days. If you plan to do sustained circuit work, consider the DB2429XP or DB2429RP compounds instead.

Are the DB2429SP pads copper-free?
Yes. The SP compound is N class compliant, meaning it meets current and upcoming North American regulations that restrict the use of copper in brake friction materials. Copper particles in brake dust have been identified as a significant source of waterway contamination. N class compliance ensures the DBADB2429SP pads are legal in all US states, including California and Washington, which have the most stringent copper-restriction schedules.

What does ECE R90 certification mean for brake pads?
ECE R90 is the United Nations Economic Commission for Europe's brake pad performance regulation. Certified pads must undergo independent lab testing to verify that their friction performance is within 15 percent of the OEM pad they replace, in both hot and cold conditions. ECE R90 certification on the DBADB2429SP means every production batch has been independently verified to match or exceed the stopping performance of the factory Honda and Acura rear pads. It is one of the highest standards applied to street brake pads sold globally.

How many pads are included in the DB2429SP set?
The DB2429SP is a full rear axle set of 4 pads: one LH Inner, one RH Inner, and two Outer pads. You receive everything needed to complete the rear brake pad service on both sides of the vehicle in a single order. High-temperature lubricant, a servicing sticker, and bedding-in instructions are also included.

Can I run the DB2429SP on the track?
The DB2429SP is a street performance compound first. Its 438 degrees C ceiling is adequate for occasional autocross and short track sessions with adequate cooling laps. For sustained circuit driving, repeated threshold braking, or dedicated HPDE and time-attack use, upgrade to the DB2429XP (Xtreme Performance) or, for full race use, the DB2429RP (Race Performance). The RP compound is not road legal.
