How to Pick a Miata Coilover

If you don’t like the Miata coilovers mentioned thus far, check out these features to choose something. Each of these customizes a package or setup to work for your vehicle and preferences.

Vehicle Match

The shocks and springs need to fit your vehicle. For a Miata this means not only that it suits Miata’s in general but also that it fits an NA, NB or NC model. Not every set of coilovers is suitable for every style of Miata. Do not purchase a set for NB vehicles. unless it specifies it is suitable.

Overall Weight

You need shocks that will support the weight of your vehicle. Once again, various models of Miata weigh differently. Suspension and coilover systems should support assorted weights. The bulk of the vehicle should fit in the middle. If your vehicle is heavier than what the suspension can support your risk overworking it. If it weighs less, then you paid more for something you don’t need.

Coil Spring Angle

If the spring angle is off it could affect how the wheel moves. Improper angle means the spring could bow or it could bind. Use a protractor to clarify the angle of the current suspension system in the vehicle. Measure the angle as compared to the rear axle in a rear spring or the control arm of the front spring.

Motion Ratio

Motion ratio is related to the speed at which a spring compresses when the wheel moves. Measure the pivot point of the control arm at the point that it connects to the frame to the center line of the spring. Also measure the center line of the pivot point to the same of the lower ball joint. These numbers will give you the motion ratio when you input them into an online calculator.

Spring Length

You need enough space for the suspension to actually do its job. This means at least 2 ½” of compression space, which could go up to as much as 4” or more. Measure the distance between shock mounts to determine the length. For those who don’t currently have coilovers you may need to mock up the size to get this number.

Upper Mount Style

Pillow ball mounts use spherical bearings for joints to offer precise handling but higher vibration. Rubber mounts provide moderate deflection, stiff setup but a good design for the streets. Stock or OEM mounts proffer a smooth ride but moderate to low performance.

Spring Rate

This number concerns how smooth your ride will be. Lower numbers give a soft ride but also reduce control. Higher numbers give a stiffer ride but more command while driving. The chosen number is your preference but can be adjusted as needed by approximately 2k/kg in either direction. Any more and you must re-valve the system first.

Budget Available

Coilovers are in every price range. The key is to know how much you’re willing to spend. If you have an unlimited budget, you can find coilovers upwards of $1,000 or even $2,000. Otherwise, several are under $200 as well. You get what you pay for, however, so make sure to get a better quality set. That’s crucial to get the best performance out of your vehicle.

Purpose

If you plan to drive the vehicle everyday, get a different style of coilovers than if you plan to only drive on the track. A vehicle that needs to be used for track purposes and street driving at the same time will have different requirements from a vehicle only intended for one or the other.

A low and stiff ride, like that for daily driving, is a budget style. The advanced control and handling means spending a bit more for higher quality.

FAQs

Before we close up, take a look at some of the frequently asked questions about Miata coilovers to choose the suitable product or to properly use them. Make sure to know what you’re looking for and what you’re getting.

What is the Best Suspension for NB?

The 1998 to 2005 Miata, or the Miata NB Chassis, is mediocre as far as these Miata Chassis go. The NA was made 10 years before it and the NB 10 years afterward. The best suspension depends on what you want out of the vehicle.

  • For an inexpensive or basic setup the TEIN Street Basis or Advance Z are decent options. They provide good value and basics for your money.
  • For a street warrior the Godspeed MonoSS Or even the Megan Racing EZ II are fine choices. They provide better shock oil, which keeps the unit from getting overheated.
  • For street or track drivers the BC Racing Version is a good option for the NB. This allows for better shock to make the vehicle more comfortable on the track.

What’s the Best Suspension Set-Up for Miata?

This is a tough question because everyone has an opinion. Overall, some of the suspension systems with the best reviews include:

  • FATCAT Bilstein
  • TEIN Mono-Flex
  • JIC Monotube
  • AFCO
  • Ohlins DFV

It depends on what you’re looking for and how much you’re willing to spend. The above options are listed in order of lowest price to highest.

Are Used Miata Coilovers Worth It?

You can buy used coilovers, but it’s important to know what you’re looking at. First, research the brand for quality and durability. Also, make sure that it’s a legal kit and can be reasonably serviced. Next, look for:

  • Cracks
  • Broken studs
  • Deformation
  • Too much play
  • Loose seal assembly
  • Leaks
  • Tool damage
  • Bump stop included
  • Rust/pitting

Any of these signify that the coilovers are no good. If you’re not inclined to put in the work, go with brand new. Buying used requires a lot of effort.

How to Install Coilovers Miata?

The installation process for the coilovers may seem extensive, but the process is not complex. If you prefer, contact a professional who will do it for a nominal fee.

  1. Remove 2 nuts holding OEM top mount to the shock tower. This allows the shock to be removed.
  2. Pull down on the rear hub and remove it from the wheel well.
  3. Use spring compressors to remove the top nut that holds the OEM top mount to the strut.
  4. Put the pieces back in the correct order.
  5. Install OEM top mount on racing coilover.
  6. Tighten the nut as much as possible.
  7. Slide new coilover into position. Line it up with top mount studs in the shock tower.
  8. Reinstall the nuts holding the entire mount onto the vehicle. This is accomplished inside the trunk.
  9. Reinstall the metal cover over shocks and clip the carpeting back down.
  10. Lift up hub to cover the bottom section of the shock and slide the bolt through the lower shock bushing to attach the pieces.
  11. Fasten the bolt as tightly as possible and attach the sway bar end link to the sway bar.
  12. Reinstall the wheel.
  13. Repeat on other wheels.

How to Adjust Miata Coilovers?

The process to adjust your Miata coilovers is simple, but it can be time consuming. Follow the steps below and then put the wheels on, drive the vehicle and see if it’s suitable. If it’s not then repeat the process until you get the correct height.

  1. Loosen the locking collar.
  2. Bring it down until tight and use a tape measure to grab on.
  3. Calculate the current distance.
  4. Loosen the shock out of the lower mount using a spanner but don’t loosen the spring perch.
  5. This adjusts the height.

How Long Do Coilovers Last Miata?

Coilovers should last at least 50,000 and up to 75,000 miles. This depends on how tough you drive the vehicle and what type of terrain you’re driving on as well.

Verdict

Overall, the Yonaka Motorsports Coilovers are the best option. These offer flexibility, durability and control. You get 28 levels for dampening and a monotube for shock absorption. If you’re not keen on this one, however, the others mentioned in this article are decent as well. Or choose your own by checking out the features listed above.
