PRODUCT INFORMATION

DBA DBA3051S-10 provides a vehicle-specific rear direct-replacement brake rotor for the 2018, 2021 Subaru WRX.

The T2 slot pattern continually refreshes the pad surface and provides exit paths for friction dust and gases during repeated stops. DBA positions this configuration for enthusiastic road driving, repeated high-energy stops and appropriate track-day use, conditions that can expose the limitations of basic replacement friction components.

How This Rotor Is Used

This part is intended for enthusiastic road driving, repeated high-energy stops and appropriate track-day use. It retains the vehicle-specific mounting dimensions shown in the fitment data and installs in the original component location.

Frequently asked questions on Alcon Brakes

Why buy from Alconkits.com?

Can I buy Alcon Brakes and parts somewhere else?

Yes, some general automotive retailers and online marketplaces may list Alcon brake kits or individual components. However, Alcon brake systems are engineered, vehicle-specific systems, not commodity parts.

When purchased from Alconkits.com, you are buying directly from a specialist Alcon distributor with deep application knowledge, fitment validation experience, and long-term service support. This ensures you receive the correct configuration, pad compound guidance, wheel-clearance assistance, and ongoing support throughout the life of the brakes.

Why should I buy this kit from Alconkits.com instead of a retailer like eBay or Amazon, or marketplace?

Alconkits.com specializes exclusively in Alcon brake systems. We are not a general parts reseller.

When you buy from Alconkits.com, you get:

  • Application-specific guidance for heavy trucks like the Ram TRX
  • Fitment advice on your brakes to ensure they clear your wheels with guaranteed compatibility with your vehicle.
  • Wheel-fitment and clearance validation support
  • Pad compound recommendations based on real-world use (street, off-road, towing, track)
  • Access to replacement pads, rotors, seals, and service parts long after purchase
  • Lifetime technical support from Alcon brake specialists

Most marketplaces can sell a box. We support the entire brake system lifecycle for as long as you own it.

What makes Alcon big brake kits different from other aftermarket brake options?

Alcon brake kits are engineered systems, not assembled collections of parts.

Each kit is designed with:

  • Vehicle-specific caliper piston sizing
  • High-mass rotors for thermal capacity on heavy vehicles
  • Motorsport-grade materials and manufacturing processes
  • Compatibility with factory ABS, traction control, and master cylinder

This results in more consistent pedal feel, better heat management, and superior durability compared to budget or generic big brake kits.

Are Alcon brake parts “one-size-fits-all”?

No. Alcon brake kits are application-specific.

Vehicle weight, intended use, rotor size, caliper configuration, and pad compound all matter—especially on high-performance cars and trucks. Selecting the wrong configuration or pad compound can reduce braking performance, increase noise, or accelerate wear.

This is why buying from the specialist distributor, Alconkits.com, matters.

What type of driver is DBA3051S-10 Street Series T2 Slotted Rear Brake Rotor - 2018, 2021 Subaru WRX for?

Manufactured by DBA, we recommend this as being suitable for the following driving styles:

After purchase support questions.

What happens if I need pads, rotors, or service parts in the future?

This is THE question to ask. Alcon brake systems are fully serviceable.

When you purchase from Alconkits.com, you have long-term access to:

  • Replacement brake pads
  • Replacement rotors
  • Seal kits and service components
  • Technical guidance for maintenance and service intervals

This is a major advantage over marketplace sellers who may not support the product after the sale. We know what fits, we stock it, and we don't sell you parts you don't need.

Why does this Alcon brake kit cost more than stock brakes or some aftermarket options?

Alcon brake kits are built to deliver higher performance, durability, and consistency than OEM or budget aftermarket brakes.

The cost reflects:

  • Larger, higher-mass rotors for heat control
  • Precision-machined multi-piston calipers
  • Motorsport-grade materials and testing
  • Long-term serviceability and support

This is not a cosmetic upgrade—it is a functional braking system designed for demanding use.

Is Alconkits.com an authorized Alcon distributor?

Yes. Alconkits.com is an authorized and specialist Alcon distributor with one of the largest Alcon-focused catalogs and knowledge bases available.
