How to Xida

Xida Race
Xida XL
Xida ACE

Before we dive into specifcs of each Xida variant, you will need to determine what your target ride height range is. This is the primary input required. Measure at pinch weld front and rear. Go do that now then come back and read the tech stuff below.

Supermiata Xida Race
The original and now gold standard, Supermiata Xida coilover system was designed from scratch to offer the highest possible performance in a competition environment. They are shorter than OEM length in order to provide the necessary bump travel range when used on a lowered Miata in a competitive setting. Because of the high-end technology, materials and exceptional valving sensitivity, they happen to ride extremely well on the street. Customers have been using them on street cars with great results, provided the low ride height works for their usage. Xida Race are optimized to function best in the 4” to 5.25” pinch weld height range.

-Xida Race users want the maximum amount of grip/performance/handling and are willing/able or prefer the lower ride heights.
-Xida Race’s adjustment range tops out around 5” on heavy cars (MSM, any car with full options + rollbar and both tops, etc).

Supermiata Xida XL
The new Supermiata Xida XL are the exact same technology/valving/materials as the original Xida. They are simply longer, within a few millimeters of OEM length in order to function properly at ride heights above 5”, up to OEM height.

Reasons you may wish to go with Xida XLs:
-You do not wish to lower your car significantly, whether for personal aesthetic preferences, logistical reasons like speedbump or driveway clearance, or simply ease of entry into and out of the car.
-You wish to install them on an Exocet or Catfish kitcar that uses Miata underpinnings.
-You are using drop spindles on your Miata, which require near OEM length shock bodies.
The extra length of the Xida XL shock body allows us to introduce several exciting new Xida variants:

Supermiata Xida Ace

By adding a remote canister to maintain the nitrogen volume, we have enough room inside the Xida XL shock body to implement the electronic semi-active Ace valve in an NA/NB application.
The same application notes apply:

-Ride height from 5” up to OEM.

-Standalone accelerometer and two button wired fob.

Xida ACE are electronic self-adjusting dampers using Tractive’s DDA piston. This system controls both rebound and compression. Same shock as the base Xida but with a magic wiring harness sprouting from the top. The ACE system is like today’s high-end OEM systems, in that it is continuously adjusting the valve in 100hz (10ms) over the full range in force increments as small as 2lbs. That's very fine tuning of damping force based on the accelerometer and user inputs from the small dash mounted control unit.
