New Product Release!! Mazda 3 and Mazdaspeed 3 Oil Cooler Kits

Are you built and tuned? Are you a track Junkie? Are you both? Keeping the motor in your 2.3L DISI engine as cool as possible is going reduce knock and prolong engine life. Preventing the oil from exceeding normal operating temperatures will extend the life of your oil by reducing temperatures that prematurely break it down and increase engine wear. The OEM oil cooler uses a coolant based heat exchanger to keep the oil cool. Adding the JBR oil cooler will reduce the rise in coolant temperatures often seen when on track or during extreme temperature conditions.
The JBR Mazdspeed 3 Oil Cooler Kit employs a 19 row core constructed out of aluminum corrugated-fins & internal tubular plates greatly increasing both thermal efficiency and mechanical strength, so you get the smallest, lightest and more importantly, the most efficient oil cooler package.
Custom length commercial grade -10AN fittings and large ID stainless braided lines are the key to minimizing the pressure drop and making for an easy installation.
The polished billet aluminum sandwich plate incorporates an 1/8″ NPT port for additional gauges and sensors.
A custom mounting bracket and stainless steel hardware keep the core solidly mounted out front of the radiator maximizing its exposure to incoming airflow resulting in an oil temp reduction of over 28⁰F.

Suspension Part One: The Basics

Let’s start with the basics. Most seasoned car guys are aware of a choice between spring upgrades and coilover suspension systems. In the most basic sense, a spring refers to an elastic object with capability to store energy. For the sake of automotive suspension, the coil spring is referenced.

The rate of a spring directly relates to its deflection in a given load capacity. To get more specific to our automotive application, this coil spring is a compression spring. By definition, as load is increased, this spring becomes shorter. This is where roll occurs in cornering. OEM applications require a spring with a low spring rate to provide driving comfort and longevity of shocks/struts.


The OEM shocks and struts are hydraulic dampers. The job of a hydraulic damper is to control inconsistencies in form of oscillations of the spring. Lost yet? Think of it like the spring being a coarse control, while the damper is a fine control. The damper utilizes a piston with an orifice to transfer a gas or fluid through a piston chamber. The energy created from movement is converted to heat, which is dissipated through the gas or fluid. In an OEM application, this orifice is usually a fixed size. The size determines the rate at which the fluid transfers. The rate of fluid transfer relates to the rate at which the damper moves.


A spring upgrade is an inexpensive solution to accomplish a limited goal. Changing your coarse control value gives you an easy performance gain. By stiffening the spring and causing the OEM damper to sit at a more compressed average position cornering performance will be increased, but excessive load will be caused on the damper. Because of the fixed orifice, the damping and rebound rates are also fixed, which limits your fine control.


Upgrading the suspension as a whole will net the best performance gains and long-term reliability. This is where options of a coilover suspension system come into play. The top level systems are designed with every control parameter in mind. Rather than limiting the setup with a fixed orifice, variable orifice valving is used. This allows adjustment. For the best control over your suspension, independent adjustable damping and rebound are desirable. This, in simple terms, means that user inputs allow both the up-stroke and the down-stroke of the piston in the damper to be controlled independent of one another.

In a street application, comfort is obviously going to be a concern. Though springrates are fixed in suspension systems via the compression spring earlier discussed, the damping and compression values are able to be changed. By setting these to softer settings, the dampers will absorb more road turbulence. This allows the cabin to be more level and comfortable.

In a track application, the only thing to be worried about is performance. Setting the damping and rebound to a stiffer setting will net the least roll in and allow for best cornering performance. This holds true until a stiffness is achieved in which rather than the body roll absorbing the sideways movement, the vehicle starts to slide. This is all dependent on road conditions, vehicle setup, etc. This is why adjustability is key.

Just Bought a Focus ST! Where do I Start?

So you just bought a Focus ST and you are probably looking for an overview of general knowledge, from what oil to use to what performance modifications are best to start with. With expert knowledge from tuners, manufacturers, and retailers in every corner of the ST community, it may be difficult to determine where to start. Here is a quick cheat sheet of info you need to know.

1. What oil do I use?

When choosing an oil, you will encounter a broad range of opinions. Luckily, lubricant technology has come a long way. With conventional, semi-synthetic, and full synthetic options on the market there is a broad range of choices. From experience, we recommend a full synthetic oil in the Focus ST. To understand what the differences in oils are, one must first understand how to read the packaging content.The manufacturer recommends a 5W-30 oil. Let’s break that number down. Viscosity is a fluid’s resistance to flow at a given temperature point. This measurement is taken at two points in rating oil. 5W refers to the oil’s viscosity at 0*F. 30 pertains to the oil’s viscosity at 212*F. These ratings are made through SAE guidelines. There are many full synthetic options on the market for 5W-30. Pennzoil Platinum, Mobil 1, and Royal Purple are a few great choices. 

While oil choice is very important, another very key factor in engine performance and longevity is service interval. Ford recommends changing the oil every 5000 miles. This rating is made with a lot of variables in mind. It is best practice to perform a Used Oil Analysis, commonly referenced as a UOA. Blackstone Labs is the industry leader in these tests. A standard analysis costs $28 and the test kit is free. This will help you determine your engine’s health and a proper maintenance interval.

2. This is my daily driver. Is this vehicle reliable when modified?

The Focus ST is an economy vehicle with performance as a focal point. This being said, Ford designed the vehicle knowing full-well that owner’s would be looking to modify it. The Focus ST is able to be modified pretty substantially without sacrificing much reliability. Following a proper modification path is key to keeping your ST healthy, while getting more enjoyment out of its performance.

3. What are the best “first mods”?

Oil Catch Can – The first modification on every Focus ST should be an oil catch can. The factory PCV system is designed with emissions in mind. In most vehicles, port injection is utilized. This allows fuel to spray before the valves. Fuel acts as a cleaning agent, preventing recirculated particulate emissions and other blow-by from building up. In a direct injection application, like the Focus ST, the fuel is injected directly into the cylinder. The fuel is not able to clean the valves in this manner. Over time, gunk will build on the valves and cause a drastic loss in performance. Adding an oil catch can prevents these from hitting the valves and building up.


Rear Motor Mount – The OEM rear motor mount is a weak point on this vehicle. The OEM component was designed with comfort in mind. It uses a soft bushing that eliminates transfer of NVH (Noise, Vibration, Harshness). This is a major compromise in performance. Allowing for slop in engine movement, this weakens the transfer of power to the ground. Results of this are more wheel hop and sloppy shifts.


Cobb Accessport w/Tune – The stock tune accommodates for a large range in climates, driver conditions, etc. It is also mapped with fuel economy as a forefront. The Cobb Accessport not only allows you to flash a custom map to your vehicle, it also allows you to monitor up to 6 parameters at a time. This means that not only will your ECU be mapped to your specific desires, but you will also be able to keep an eye on how things are working. This allows you to see small problems before they become big problems.

Front and Rear Sway Bars – The Focus ST has a lot of body roll from the factory. This is designed with driving comfort in mind. The addition of aftermarket sway bars help to counter this. This will allow for much better cornering and balance. The vehicle will perform better in the twisties, at AutoX, and on a large track in road racing.

4. Where can I obtain more info? 

The best resources for information on this platform are blogs and forums. While Facebook groups are quick and easy to get an answer on-the-fly, sometimes answers can be incorrect, inferred, or misinterpreted. It is best to obtain information from credible sources.

FocusST.org is the leading forum on this platform.

Stratified Automotive Controls has a host of information on ECU calibration and fueling related topics.

Edge Autosport has a lot of information on what brands are the best and which parts suit your needs.

JBR Featured Owner #1 – Adam Clover – 2013 Focus ST

Being the Ford Focus ST is a cross between domestic economy and European hot hatch performance, the market spans a wide demographic. This unique cross creates a very interesting community that is different than all others. We see owners from [as jealous as I am to say it at that age] high school students in their first car all the way up to middle-aged performance enthusiasts.

At James Barone Racing, we have observed that with the wide demographic, there is also a great acceptance and warm welcome to new owners. This community is a great place to be and the owners are really a whole different breed than most car enthusiast groups. We’d like to introduce the community to some of these members that stand out the most to us. We would like to introduce our first JBR Featured Owner, Adam Clover.

Living in Green Bay, WI; Adam is a member of Wisconsin ST Club. The Wisconsin community has a strong level of respect for all types of enthusiasts. Adam came from a family background of car enthusiasts. His grandpa restored old cars, and since Adam was 5 he loved to help. While he was helping, he learned a lot along the way. We all know that once cars get into one’s blood, it never fades.- the passion that drives us all to tinker, to love and appreciate the machines for the true beauty they possess.

Starting off with a 1990 Honda CRX, Adam had some work to do for his first project car. Rust plagued the rear of the vehicle, and as a true car guy Adam realized that needed to be addressed. To fix the problem, he bought a second donor vehicle and cut both vehicles in half. He then proceeded to use his fabrication skills to do some surgery and stitch the two back together.

A few vehicles later, Adam found himself with the Focus ST we all know and love. There are corners of the community focusing (no pun intended- ok maybe a little) on aesthetics; performance; autocross events; road course racing; and even the simple utilitarian nature of the ST picking up the kids and transporting snowboards, skis, bikes, and more. Adam happens to have a mixture of a few of these interests.

Adam started by addressing the aesthetic shortcomings of the ST. Starting with a set of Eibach Sportline lowering springs. Shortly after, he dug into the head unit to replace it with a Nexus 7 tablet. Being a maintenance mechanic by trade, Adam has some fabrication skills. He eventually graduated into a few custom cosmetic modifications including wing risers, a custom grill, and a custom crash bar; Adam made his ST one of a kind.

After addressing the cosmetics, Adam moved on to performance. Realizing the hunger for a large amount of power, Adam went for everything at once. Adam’s Focus ST features the following performance modifications:

  • Custom Cold Air Intake
  • Custom 3” Side-exit Exhaust
  • OCD Downpipe
  • ATP GTX2971 Turbo Kit
  • Stratified Xtra Fuel Kit
  • Cobb Accsessport V3 w/ Stratified E42 Tune
  • Cobb Rear Motor Mount
  • JBR 80/88 Duro Side Mount Package
  • Boomba Short Throw Shifter + Bushings
  • CX Front Mount Intercooler

Adam’s favorite modification to his ST has been the Stratified E42 port fueling tune. This is a great bang-for-your-buck modification on every level of ST, from stock form to big turbo. It cannot be stressed enough how a proper calibration is key to getting the most our of your driving experience.

We spoke with Alex at Stratified about the tuning process…

  “There are several important aspects to consider when building a car. It is important to know how the car will be used in order to determine the power level needed and the modifications needed to get to that power level reliably. With modern turbocharged vehicles it should always start with a tune. We use the COBB AccessPort for its capabilities and versatility and the excellent support. 

Adam’s car was a joy to tune. He spent the time and decided on the direction he wanted to take with the car. When he came to us we were able to address those needs with an ATP GTX2971 big turbo kit, Stratified  Aux Fuel System, and full custom tune. He had the supporting modifications needed and since he purchased quality and proven parts as part of this kit, he was able to reach his power goals of 400+whp reliably quickly. Adam was also very quick to respond with data and feedback during the E-tuning process and this allowed us to progress quickly towards his goals. The advantage of coming to us with a clear goal and getting the correct parts and tune is that we can address those needs without having to go through several setups, kits, and headaches that can leave a lot enthusiasts disappointed and cost a lot more in the end. If you have further questions regarding tuning and setting up your Ecoboost Focus don’t hesitate to get in touch.”

This past year has been a lot of preparation on the ST, and now that things are where Adam would like them to be for the most part he plans to enjoy it in the coming Spring and Summer. He would like to use the well-built machine to get some track time under his belt. We hope to see you at the track alongside our test vehicles this year, Adam!
