Product Details

The Wilwood AERO6 Big Brake Front Kit is engineered specifically for dedicated road racing applications on 2001-2006 BMW E46 M3 models. This championship-proven brake system delivers superior stopping power, fade resistance, and thermal stability for high-performance track use.

AERO6R/ST Six-Piston Calipers:

  • Forged aluminum body with Type III Mil-Spec medium gray hard anodized finish for superior wear and corrosion resistance
  • Wider body design accepts 20mm thick brake pads for extended service life
  • Thermlock® pistons reduce heat transfer from pads to caliper, increasing fade resistance and extending component life
  • Internal damper springs and high-temperature piston seals maintain consistent pedal height throughout racing sessions
  • Piston volumes matched to OE master cylinder output and ABS controls for seamless integration
  • Compatible with manual brake conversions using balance bar pedals and appropriately sized master cylinders

Spec37 Alloy GT Competition Rotors:

  • 14.00-inch diameter directional vane design for maximum cooling efficiency
  • Dynamically mounted to OE hubs with weight-saving forged aluminum hats
  • Hard anodized hats provide superior wear resistance at load-bearing surfaces
  • Minimized unsprung and rotating weight while maintaining thermal stability under sustained high-heat competition conditions

Complete Race-Ready System:

  • Mounting brackets with premium-grade fasteners secure calipers to spindles in stock location
  • Minor modification to spindle dust shield required (see assembly instructions)
  • High-temperature, high-friction endurance compound race pads selected for application
  • Stainless steel braided flexlines included for complete installation

This front brake kit is designed for serious track enthusiasts seeking maximum braking performance and reliability in demanding racing conditions.

Great . Will by from again . Y'all must have made some management changes because your service has improved . Big change from the way it used to be . Still need to work on your returns policy but your on the right track . Keep it up .

Thanks

will wait to see how it shows up

Found exactly what I was looking, at a great price, would definitely order again!

Cheaper than most. But processing and shipping took longer than jegs or summit

Easy to use site, hopefully my shipment is speedy!

as long as part is not damaged when it gets here I will be happy

There is no way of knowing if item is in stock or will be dropped shipped immediately

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!
