PRODUCT INFORMATION

BMW M3 G80 / M4 G82 / M2 G87 — Full Big Brake System

Maximum Stopping Power — Front & Rear

This is the most comprehensive brake upgrade available for the BMW M3 G80, M4 G82, and M2 G87. The Full Big Brake System replaces all four corners with Paragon big brake hardware — a PA035 6-piston front caliper and PA025 4-piston rear caliper, both with matched compound pads. Nothing else you can do to this car's brakes will have a greater effect.

What’s Included

  • Paragon PA035 6-piston front big brake kit 370mm
  • Paragon PA025 4-piston rear big brake kit 355mm
  • Hawk HP660 race brake fluid
  • Matched pad compound: P3, R5, or R7 — applied to both kits
  • Choose Hard Anodized or Nickel Plated calipers

Why These Parts

Pad Compounds

Available in P3 (performance street), R5 (track — high heat tolerance) or R7 (race — maximum friction, requires heat to activate, track use only). Compound applies to both front and rear kits.

  • P3 — performance street — stronger bite, handles moderate heat
  • R5 — track — aggressive bite, high heat tolerance
  • R7 — race — maximum friction, requires heat to activate, track only

Paragon PA035 6-Piston Front Big Brake Kit — 370mm

The Paragon PA035 6-piston caliper replaces the factory M front caliper with a significant increase in clamping force and pad area. Direct bolt-on to the G chassis front upright — no adapter plates required.

Paragon PA025 4-Piston Rear Big Brake Kit — 355mm

The Paragon PA025 4-piston rear caliper replaces the factory M rear caliper, completing the four-corner upgrade. Matched rotor diameter and pad compound ensures balanced braking bias front to rear — critical at track speeds.

Hawk HP660 Race Fluid

HP660 race fluid is included because the factory fluid's dry boiling point is the first limit you'll hit under sustained track braking. A fresh fill takes that variable off the table before the first session.

Fitment

BMW M3 G80 / M4 G82–G83 / M2 G87 · 2021–2025

Fitment note: Both front and rear big brake kits are direct bolt-on to the G chassis M uprights. Wheel clearance should be verified — G chassis M cars typically run 19"+ wheels which accommodates these caliper sizes, but confirm with your specific wheel before ordering.

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 BMW G8X M2/3/4 — Full Big Brake System for?

Manufactured by Alcon Brake Kits, we recommend this as being suitable for the following driving styles:

  • Sporting
  • Street/Track
  • Track/Race

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.

Our team has extensive experience supporting Alcon brake systems across trucks, SUVs, performance cars, and specialized applications.

  • Direct access to Alcon brake experts
