Powerbrake X-Line X6EL 6-piston / 350x34mm Front Brake Kit, '12-17 Focus ST/RS


Powerbrake X6EL Big Brake Upgrade

Powerbrake designs and manufactures high-performance and motorsports level brake components that offer exceptional performance and durability at surprisingly competitive prices. This is made possible through state of the art CAD, FEA and CAM software as well as cutting edge 5-axis CNC production equipment that results in design and production efficiency that gets passed on to customers and ultimately translates into competitive product pricing.

Powerbrake's base of operations is South Africa, and Vorshlag has worked with this company since they first brought their products to the U.S.A. We tested Powerbrake's upgrade kits on our own street and race cars before we felt confident to sell them - we now trust our brakes to Powerbrake!

Specifics For Focus ST/RS Front Kit

This Powerbrake kit is made to replace the front brake components on the 3rd generation Focus ST or RS chassis - rotors, calipers, lines, and brackets. The engineers at Powerbrake have designed this kit so that when using the factory rear brakes and master cylinder, hydraulic ratio and pedal travel will not be affected. 

There are many advantages of the X6EL 6 piston brake kit for the Focus.  We often see that with motorsports grade components your "costs per lap" will go down. True racing calipers look after the pads and rotors better than the OEM calipers with track pads. This means you will see drastically improved brake performance, with less wear, for a longer period of time.  Another great benefit is a reduction in unsprung weight.  We often see a weight drop of 2-8 p[ounders per corner when going to Motorsports brakes like this. The change in braking feel over the OEM cast Brembos is always eye opening as well, and the stopping performance is exceptional.

Wheel Fitment:

This brake package should fit under most 18-19" wheels. Please contact Vorshlag for a "brake template" of this caliper/rotor combination to check inside your wheels to verify fitment.  In the past converting to a 6-piston brake caliper meant also switching to a 15" rotor and buying new wheels to fit over everything...the cost add up quickly.  Powerbrake's X6EL gives you all the benefit of a 6-piston caliper without needing such a large rotor, which means you most likely already have wheels that fit over these brake.

Powerbrake Rotors

The disc friction rings used in Powerbrake X-Line assemblies are cast from a proprietary high-carbon iron alloy, cast in Europe, that provides excellent durability and stability under the high thermal loads experienced during race, track day & fast road driving.

The X-line discs feature curved, directional, staggered cooling vane design that increases cooling vane surface area for optimal cooling. The included 5 color Maximum Temperature Recording (MTR) rotor paint provides a permanent record of the peak operating temperatures reached by the rotors during use. The colors equate to:

  • Blue paint – turns light brown at 527 deg F
  • Green paint – turns white at 860 deg F
  • Orange paint – turns yellow at 1022 deg F
  • Red / Pink paint – turns white at 1166 deg F
  • Wide Red paint strip – various shades from 219 – 2318 deg F

NO BRAKE PADS ARE INCLUDED IN THIS KIT

This Powerbrake X-line brake upgrade does not include pads - to allow you to choose the brake pad supplier you are comfortable with. Some folks like to stick with what they know, and that is why the common FMSI D1116 pad profile was used for this caliper - many pad suppliers make this common pad shape. You can see part numbers for this pad from several brake pad manufacturers in the drawing below.

Powerbrake also offers a range of brake pads to fit the X6EL caliper, which cover all types of street, dual purpose, and racing uses. Please see the brake pad options for the Powerbrake X6EL caliper in this "Brakes" section. Feel free to call Vorshlag for pad brand and compound advice.
