10-piston clamping architecture
Differential bores — 4× 28 mm leading, 6× 30 mm trailing — equalize pad pressure across a long pad. The result is even wear, predictable bite, and pedal feel that stays linear as temperature climbs.

Evolution EB10 10-Piston Front Big Brake Kit
The EB10 is built for front-axle applications that demand very high brake torque, stable pedal feel, and repeatable heat management. A two-piece forged 10-piston caliper drives a long pad against a 420 or 440 mm two-piece rotor, delivering controlled initial bite, linear modulation, and consistent stopping confidence lap after lap or stop after stop on the street.
Why Builders Choose the EB10
Two-piece forged aluminum body
Forged construction resists caliper flex under high line pressure, which protects pedal travel and modulation. High-temperature gloss coating handles repeated heat cycles without losing finish.
Heat-insulated pistons
Two-piece heat-insulated pistons with dust boots reduce heat transfer from pad to fluid, helping fight pad fade and fluid boil during sustained or repeated hard braking.
Two-piece rotors, iron or CCB
Ø420 or Ø440 mm × 40 mm internally vented rotors in heat-treated high-carbon iron or carbon-ceramic composite. Directional left/right design improves cooling airflow at speed.

Will It Fit? Your 3-Step Check
Important: The EB10 is a platform-adapted big brake kit. Caliper bracket availability depends on the application. Contact us with full vehicle and wheel details to confirm fitment.
1. Wheel Diameter
Minimum wheel size: 20 in or larger.
2. Spoke Clearance
Minimum spoke clearance: 108 mm (inner-rotor-to-inner-spoke distance).
3. Vehicle & Wheel Geometry
Spoke geometry, offset, and barrel shape vary widely between wheel models — a printed clearance template or trial fit is strongly recommended before final purchase.
Installation & Break-In
- Radial caliper mounting with vehicle-specific CNC bracket.
- OEM-style brake line fittings on the chassis side for clean integration.
- Bedding-in procedure is required to transfer pad material onto the rotor face and stabilize the friction layer.
- Professional installation by a qualified brake technician is recommended.
Frequently Asked Questions
What does the 10-piston caliper actually do for braking performance?
The 10-piston layout (4× 28 mm + 6× 30 mm) spreads clamping force across a long pad, which evens out pad pressure, reduces taper wear, and supports controlled initial bite that stays linear as rotor temperature climbs. Total piston area is 67.0 cm² per caliper.
Which rotor sizes and materials are available?
Two-piece rotors are offered in Ø420 mm × 40 mm and Ø440 mm × 40 mm, in heat-treated high-carbon cast iron or carbon-ceramic composite (CCB). Iron rotors come in curved slot, grain slot, wave slot, or drilled-and-slotted face patterns. CCB rotors are cross-drilled and floating.
What wheel size do I need to clear the EB10?
Minimum 20-inch wheels are recommended, and the inner-rotor-to-inner-spoke distance must be at least 108 mm. Wheel offset, spoke geometry, and barrel shape vary, so we strongly recommend a clearance check or template fitment before ordering.
Will this kit fit my car?
The EB10 is a platform-adapted big brake kit. Caliper brackets are CNC-machined to suit the application, and brake lines use OEM-style chassis-side fittings. Contact us with your vehicle year, make, model, trim, and wheel specs so we can confirm fitment and bracket availability.
What's the difference between the iron and carbon-ceramic pad options?
Iron-rotor pads operate from 0–600 °C with an average μ of 0.38. Carbon-ceramic pads operate from 0–700 °C with an average μ of 0.45 and are only compatible with CCB rotors. Pads and rotors are not cross-compatible between materials.
Is a bedding-in procedure required?
Yes. A proper bed-in cycle is required to transfer pad material evenly onto the rotor face, stabilize the friction layer, and unlock full torque and thermal performance. Skipping bed-in can cause judder, glazing, and inconsistent pedal feel.
Ready to spec your EB10 build?
Send us your vehicle, wheel specs, and intended use. We'll confirm bracket availability, recommend rotor size and pad compound, and walk through caliper color and rotor face options.

Worth it.
Size: Small, Color: Black (001)/White
Living in North Dakota, staying warm is invaluable. UnderArmour Cold Gear is the only base layer the provides warmth, KEEPS warmth, and protects from the unforgiving wind. Every winter I go on the hunt for thermals, layering options and I always find others to be saggy or incredibly tight, either way, once I begin shoveling or snowblowering, and sweating, other products become soaked, sticking to skin, unbreathable and quickly your sweat stuck to your body under layers in now creating a cold,chill, freeze to your body, and on a -10F day, it can become a dangerous situation.
I honestly was hesitant to purchase UnderArmour, I felt it was too hyped up or paying for a name. BUT IT IS NOT. UnderArmour isn't a name, it is a company that has made the highest quality base layer, warmth, breathable and it really wicks sweat away; I may not know how it does it, but it works!
For sizing, I ordered a small in the women's longsleeve/turtleneck black coldgear. I'm 5ft and roughly 110lbs. I like the fit, it is meant to fit your body. I probably could wear an extra small, but I like the sleeve length in the small and it fits very well.
Stay warm folks!

Great cold gear
Size: Large, Color: White (100)/Black
Warm, very comfortable. I wear these all winter. The neck can be a little tight and the cut is definitely fitting. Its got thin like fleece on the inside that keeps you warm.

Tight but stays in place, comfy and keeps you warm
Size: Medium, Color: Charcoal Light Heather (019)/Black
I liked this shirt because it keeps me warm when I'm outside even at negative temperatures, I can work out comfortably in it and the sweat dries out soon; also, the interior of the shirt is made of a very comfortable material.
I don't like that this is very tight, cool if you want to use it under your usual sports clothes but if you want to use it as is I would suggest going up a size.
I use this shirt almost every day to work out during winter time, I've washed them several times and they still feel as comfortable as the first day.

Perfect for running!
Size: Small, Color: Black (001)/White
None of my running clothes make me feel as sexy as this underarmor does. It is so soft on the inside, which is an upgrade from their old version because I found one at the thrift store that is really scratchy. It has been through a cold wash and the dryer multiple times at this point and it is still holding up. The size is true. The material thickness is perfect for me between 45-35° F. And again with layers between 15-10° F. But I look forward more to my runs that I get to wear my underarmor. Nothing makes me feel more confident on the trail. And I love love love the turtleneck. I got all black because that is my favorite color to wear when I run and it looks perfect. It is a true black.
