New Product Release!! JBR 2016+ Mazda Miata ND/RF Oil Cooler Kits!!

Details:

Are you tuned? Are you a track Junkie? Are you both? Keeping the oil in your 2.0L MX-5 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. In addition to keeping the oil temps under control, adding the JBR oil cooler will reduce the rise in coolant temperatures often seen when on track or during extreme temperature conditions. The lack of an oil cooler from the factory makes the JBR oil cooler an essential addition for those that push their MX-5 to the limit.

The JBR 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.

Suspension Part Three: The Pertinents

Going back to our last post (if you haven’t read Part Two yet, you should), we broke down the components of what makes up a coilover system, we’ve been over deciding that coilovers are really the best option and have discussed some of the key features of a set of coilovers. Now we need to dive deeper into some of the features that are icing on the cake. These are the bells and whistles found on premium suspension systems that make them worth that bit extra.

As you will recall, compression and rebound dampening are two major points of adjustment. Some coilovers offer only compression and other more  premium coilovers offer both. Why is this important? A vehicle in a track environment, or even on some twisty backroads, will receive four types of bias. Forward, rearward, left, and right bias are the four categories. When compression and rebound adjustments can be made, and those adjustments can be made on all for corners, then one can properly address all types of bias and conditions. This allows the user to tweak their suspension to perfection for any given condition and setup. Whether it be on the your daily driven street car, your dedicated track car or the more common daily driven track car, having control over your suspension is where it’s at.

Speaking of conditions, a primary concern of many is the ability to get great track performance out of a set of coilovers that is able to be driven with comfort on the street. Range of dampening is a key factor in this parameter. A set of coilovers labeled as “street” will typically have rather soft shocks. A set of coilovers labeled as “track” will conversely be rather stiff. Having a wide range of adjustability, being able to adjust both compression and rebound are what make a good set of coilovers great for both the street and the track!

Another very important feature found on a quality set of coilovers is camber adjustment. Often times the OEM suspension setup doesn’t allow for much if any camber adjustment. Camber or Camber angle is the angle between the verticle axis of the wheels and the vertical axis of the vehicle and can commonly be seen from the front or rear of the vehicle. If the top of the wheel is further “out” in relation to the bottom of the wheel, this is refereed to as positive camber. If the top of the wheel is “in” relative to the bottom, this is called negative camber. You will rarely see positive camber on a street car or road course car. You may see positive camber on an oval track car and it would only be found on the inside wheels. Negative camber is the more common setup due to the fact that it increases grip when cornering by increasing the tires contact patch. Having the ability to add additional negative camber over that obtainable with the OEM setup is a important feature of every driver that races their car. It’s even a requirement for those that just want to achieve a low ride height combined with the aggressive look of wider tires and need to get them tucked inside of the wheel well.

To adjust camber, coilovers employ what’s called camber plates to make these adjustments. You’ll primarily see them in the front simply because the front of most vehicles with the more common McPherson strut suspension do not have camber adjustment capability. This is not often the case with double wishbone suspension and coilovers for those vehicles typically do not come with camber plates.

Hmmm… I wonder if we can’t develop a set of coilovers that will be comfortable on the street, have both compression and rebound adjustability, camber adjustability where needed and perform the job duties on the track? Yes, Yes we can!

Now that the research is done and we know what we want out out a set of coilovers it’s time to build a few sets. With prototypes completed, the fun part is about to begin. The best part of being an aftermarket manufacturer is that testing needs to be done. We’re all car guys, so naturally taking the car to the track is not exactly a chore. It’s no secret that JBR is located in the greater St. Louis area. Aside from some AutoX action, there is not much venue for legal abuse to the extent that we’d like.

JBR’s testing process involved multiple levels. Typical spirited driving is in order for the entire JBR fleet and that happens frequently. What is the fun of owning a performance vehicle without driving it like it was designed? A step above is taken in the routine AutoX outing. Often times, when some early testing is needed on a new part, AutoX is a great tool. It is legal to get some abuse on the parts on this closed course, and gets some real world data based on how the parts will be used.

Although this is the routine light duty testing, the real stamp of approval needs to be received at the peak of conditions the parts will be subjected to. This is why frequent trips to various Midwestern tracks, such as Gingerman Raceway, Road America, Mid-Ohio and Pittsburgh International must be made to get proper testing done. High speeds and high cornering forces are coupled with extensive duty cycling at these venues.

Now what’s the beauty of owning a performance vehicle? We race the same cars that we get groceries with. Clearly being able to drive the car to the track, get the abuse in, and drive it back home would get the stamp of approval. This is where the beauty of the JBR prototype coilovers came into play. Not only did they perform extremely well on track, but off track as well. Due to the large range of compression and rebound adjustment incorporated into the dampers, the vehicle is able to achieve a cushy ride feel on the streets at the turn of a knob.

Suspension Part Two: The Breakdown

Going back to our last post (if you haven’t read Part One yet, you should), we discussed some suspension basics. We know that two major components in a suspension that can be upgraded to optimize performance are springs and dampers. Springs can be thought of as a coarse control, with the dampers  being a fine control. When looking for the most performance and flexibility for different conditions, a full replacement is best. This is commonly known as a coilover system.

When looking at coilover options, an abundance of offerings will be found. Where does one begin to make choices? Spring-rate, dampening, compression, rebound, and independent adjustability of these are all items to consider when choosing a coilover system.

Spring-rate is a large factor in how a coilover will perform. Simply put, the spring-rate is defined as the amount the spring deflects over a certain load capacity. This rating can be made in either kg/mm or lbs/in. You will see kg/mm often shown as “K” and lbs/in often shown as “#” or “lb”. To understand and compare different systems to one another, use this chart:

700 lb/in = 12.5 kg/mm
650 lb/in = 11.6 kg/mm
600 lb/in = 10.7 kg/mm
550 lb/in = 9.8 kg/mm
500 lb/in = 8.9 kg/mm
450 lb/in = 8 kg/mm
400 lb/in = 7.1 kg/mm
350 lb/in = 6.2 kg/mm
300 lb/in = 5.3 kg/mm
250 lb/in = 4.5 kg/mm

So what does this mean? The stiffer the spring, the more load it will take to compress it. Essentially, body roll in cornering will become less when spring-rate is increased. Spring-rate is generally fixed rate on a set of coilovers. This coarse control by itself would result in a very “springy” ride. Rather than a tire staying planted on the tarmac, with a load applied, it would waiver between loaded and unloaded. An unloaded corner makes for loss of grip. This is where dampening comes in.

Compression dampening is the rate of reaction to a change in compression. This is the car pushing down onto the surface. The rate at which the piston compresses directly relates to the amount of compression dampening. This essentially aides the spring in absorbing fine changes in force exerted. This can be bumps in the road, slight turns, or say the car ends up on the rumble strips.

Rebound dampening does the opposite of compression, go figure. Rebound force comes into play when force is lessened on the road, say at the bottom of a dip in a pothole, in the bottom of a bump in the road, or on the exit of a turn.  More rebound will create more response on weight transfer out of a corner.

One can see how having a fixed spring-rate means that compression and rebound adjustability shifts the burden of your choice onto these variables. Most coilovers will be advertised based on how many clicks are on the dial. This refers to how many different settings there are for dampening. Although more options are better, this is not always the whole story. The range that these choices cover is really the thing to be looking at. Most users will be wanting to track their vehicle, but also have the flexibility to have a bearable ride on the street. A set of coilovers with tons of adjustments on one end of the spectrum does the user no good on the other end. This is why range is key.

Not only is range of concern, but compression and rebound do not always go hand it hand. To really dial a vehicle in for a specific setup and circumstance, these variables should be able to be controlled separate of one another. Though this feature is not something that is seen on the bulk of the coilovers on the market, it is available on quite a few and should be sought after if budget allows.

Ultimately, one must consider the use of the vehicle to make a decision. Often times, paying a little bit more money for a gain in versatility is a good choice. The better range of options offered, the more likely the coilovers will be able to accommodate for the various situations to be encountered.
