1.) Enkei NT03+M Wheel 18×9.5 5X108 40mm Silver

Owner: @thatfordfocusst
Check out this Focus ST for some awesome content!

NT03+M is designed with a perimeter brace ring that enhances the wheel strength so it’s able to resist deformation or distortion from outer forces, resulting in highly accurate steering response and strength. The NT03+M also features a racing twin valve design which allows for accurate monitoring while adjusting the pressure.

MAT PROCESS: Shaping by the MAT process reduces wheel weight by 10%-15%. Every pound of unsprung weight savings has the effect of reducing overall vehicle weight by 20lbs.

MAT Technology
Enkei developed a new manufacturing process to produce the next aluminum wheel generation. The Most Advanced Technology (M.A.T) combines one-piece cast wheel technology with a rim forming technology called spinning process. Using this new technology of casting and rim forming by M.A.T process, is critical to improve drastically the material property and strength of the wheels. Rim-Rolled technology shapes the rim to improve material elongation without sacrificing the wheels hardness.

SPEC-E
All Enkei wheels are engineered to pass rigorous testing. In fact, Enkei established its own test standard called “Spec-E,” which is tougher than JWL requirements. Enkei’s Spec-E test setting requires a higher drop point in the impact test and 20% more cycles for the rotary bending fatigue and dynamic radial fatigue tests than JWL standards. The Spec-E represents Enkei’s confidence in its technology and quality of Enkei wheels.

• Spec-E Inspected
• 690kg Load Rating Capacity
• Size: 18×9.5
• Bolt Pattern: 5×108
• Offset: 40mm
• Hub Bore: 72.6mm

3.) Mishimoto Silver Thermostatic Oil Cooler Kit Ford Focus ST 2013-2018

After a few laps on the track or some aggressive street driving, turbocharged 4 cylinder engines like the 2.0L EcoBoost in the Focus ST are known to overheat oil quickly. Even with the stock liquid to liquid heat exchanger, the EcoBoost can still run hot and risk overheating the engine’s coolant. Aggressive tunes paired with some track miles can significantly overheat your oil and wear down your engine. Leave it to Mishimoto to come up with an oil cooling solution for your Focus ST!

The Mishimoto engineers started with a large 19-row Oil Cooler and mounted it in the front of the vehicle where it receives the most airflow. The oil cooler was mounted on the passenger side as to not interfere with some aftermarket air intake systems. Application-specific braided stainless steel lines transfer the oil from the cooler to the engine and feature -10AN fittings for an easy installation. Mishimoto engineers saw consistent temperature decreases of over 30°F (16.7°C) using our non-thermostatic sandwich plate. This proved that our oil cooler kit can withstand the stress of the most extreme applications.

This oil cooler kit is available with either a Stealth Black or Sleek Silver cooler and your choice of the Mishimoto Oil Sandwich Plate or the Mishimoto Thermostatic Oil Sandwich Plate. As with all our products, this kit includes the Mishimoto Lifetime Warranty.

Please note: Mishimoto fully inspects and cleans all products prior to packaging. However, it is recommended that customers flush the oil cooler with one quart of clean oil prior to installation to remove any debris accumulated during shipping. Please feel free to contact us at [email protected] if you have any questions.

5.) VR Tuned ECU Flash Tune Ford Focus ST 2.0L EcoBoost

The Ford Focus ST ECU Tune is done by VR Tuned is one of the best upgrades you can do. The cars 2.0L turbo is already a load of fun to drive. With our new ECU calibration, you are able to gain improved performance with increases in horsepower and torque. The biggest difference when you flash your car is the overall drivability improvement. Your car will have much better throttle response throughout the gears. Where your car is sluggish off the line, huge gains of torque come in giving you a vast improvement of your 0-60mph time. Depending on mods, the midrange can increase through the curve and the top end pulls harder to redline.

Crank Horsepower Ratings:

• Stock Power: 250hp | 266ft/lbs
• Tuned Power: 278hp | 341ft/lbs

ECU Flash Options:

• Vmax Off – This is an increase or reduction of the maximum speed limit.
• Race Exhaust – This option is for those running full race exhaust systems.
• Pops & Bangs – Pops and bangs (burble tune) is the result of an ignition delay which creates an exhaust detonation when the throttle pedal is released. Caution, this process must only be used on vehicles with a full race exhaust. This may affect long term engine reliability.
• Cold Start Off – Disables the cold start system.
• DTC OFF – This option is to delete Trouble Code (DTC) related to the engine. You provide us the code.
• Some options are not available for different software version of the vehicle. We cannot know this until the factory ECU read is uploaded. If a feature is not available that is extra, we will refund you that amount. We do guarantee to provide you with the best possible performance tune.

6.) Whiteline Grip Series Stage 1 Kit Ford Focus | Focus ST 2012-2018

7.) GFB DVX Diverter Valve Ford Focus ST

GFB’s DVX takes the extremely popular DV+ Diverter Valve and adds dual venting outlets along with our patented Venting Bias Adjustment System. So not only do you get IMPROVED BOOST HOLDING and THROTTLE RESPONSE, you have total control over your BLOW-OFF SOUND VOLUME!

WHAT MAKES DVX DIFFERENT TO ANY OTHER VALVE THAT GOES “WHOOSH”?

• The DVX is not just a noise maker (like BOV spacers) – by modifying the valve operation method it offers the same PERFORMANCE BENEFITS that the DV+ does.
• It retains ECU CONTROL for the fastest possible operation.
• No other blow off valve has the advantage of GFB’s Venting Bias Adjustment, allowing you to alter the blow off sound simply by moving the adjustment lever.
• Built to last.

GFB’s DV+ design solves the longevity and boost leaking issues that are common with factory diverter valves, and also changes the operation method to “pilot actuation” to ensure better performance on stock or modified engines.

Furthermore, these benefits won’t cost you the Earth! Rather than throwing the entire factory diverter valve system in the trash (like other manufacturer’s “solutions”), the DV+ keeps what works, and replaces what doesn’t.

WHAT DOES IT FIT?

The T9654 is a duel venting direct factory replacement for the pneumatic diaphragm type BPV (Bypass Valve) used on Ford, Volvo, Porsche, & Borg Warner Turbos

WHY NOT JUST USE A SPACER?

There are many “BOV spacers” on the market that make noise. However, they do this simply by using the factory diverter valve and redirecting the air to atmosphere. Therefore, the performance deficiencies of the factory diverter valve design remain, and furthermore, the flow capacity of the factory diverter is significantly reduced because of the small venting holes used in these BOV spacers.

ECU VS VACUUM CONTROL

Other BOV kits eliminate the ECU control entirely, using pure manifold vacuum control instead. Whilst there’s nothing particularly wrong with this (that’s how the majority of BOVs work), the ECU control is MUCH FASTER, able to detect and respond to much SMALLER THROTTLE TRANSITIONS and, since it’s available, why wouldn’t you use it?

WHAT’S SPECIAL ABOUT OUR VENTING BIAS SYSTEM?

GFB’s patented Venting Bias Adjustment System is the only one of its kind in the world. By using an internal rotating sleeve, the opening of both the recirc port and the atmosphere port can be infinitely adjusted. This means that you’re not stuck with a fixed 50/50 or 100% atmosphere venting ratio; you can change it to whatever you want! As an additional benefit, because the atmosphere outlet is a single large port rather than a series of small holes, the venting sound is much DEEPER AND LOUDER than it is with a BOV spacer.

THE BOTTOM LINE IS…

The DVX offers a TRUE PERFORMANCE improvement, INCREASED BOOST-HOLDING ability, and a blow-off sound that is COMPLETELY ADJUSTABLE from factory-silent to ear shattering!
