Tecna coilover 90-05 Miata MX5


Product Description

Designed and engineered by our team to be the best riding Miata coilover available

The Lowdown: The Tecna coilover was engineered from scratch by our team to be the best riding coilover in this price range and still allow lowered ride heights. We think of these as daily driver/dual duty shocks, not race shocks. If you are focused on the ultimate handling in a competition type environment, we recommend stepping up to Xidas with much higher spring rates. Tecna damping range is roughly equivalent to the first 35% of Xida damping range. Perfect for a daily driver, canyons and HPDE or auto-x. Tecna do not require service and are intended to last the life of your vehicle. 

Why one piece body?  Tecna are fixed length, one piece body shock. Body, shaft lengths, mounts, and internal configuration are specifically engineered and maximized for this application. Unlike most aftermarket 2 piece, length adjustable coilovers that use an existing universal short cartridge with an adapter cup extension to make it fit. The upside of 2 piece coilovers is that they are cheap to produce. The downside is that they aren’t optimized for any particular platform and as a result don’t perform as well as 1 pieced (fixed length) shocks. Pro race teams and OEM’s do not use 2 piece shocks, ever. So whether you are looking for ride quality or performance, 1 piece shocks are the current state of the art .

Touring or Sport Springs? For a street focused build, stick with the Touring 6/4 rates. These will improve handling and provide amazing ride quality over any road surface. If you don’t mind the firmer ride that Sport Springs provide, you can improve response and stability with 200tw tires in HPDE or autocross driving.

Optional Swift Spring add-on
Choose this option and we will include a set of motorsports-grade Swift springs (metallic copper) for some added bling. The Swift springs gain about 5mm more min and max preload adjustment range and save about half a pound per spring. Only available in Sport spring rates. Swift springs are not pre-installed.

Tecna Handling Kit – Add a Racing Beat 15/16″  front sway bar with brace blocks and end links with a bundled discount. Fits 90-05 Miata. Optimized for 9/6kg Sport Springs. Stick with stock sway bars for standard 6/4kg Touring springs for best ride quality.

  • Racing Beat 15/16″ front sway bar
  • Two pairs Supermiata adjustable end links
  • Set of Supermiata sway bar brace blocks

Set up:  Typical available adjustment ranges are front pinch weld heights between 120-150mm (4.75″ and 6″) with the driver. Adjust rear pinch weld height 3mm (1/8″) higher than front height without driver as a starting point. We recommend 133mm (5.25″) front pinch weld height for street driven cars. Tecna Touring will give the best combination of handling and ride with stock sway bars. For Sport springs, 1″ max front bar, OEM rear. More sway bar than that will only reduce ride quality without any increase in grip or handling. We do not recommend the use of any aftermarket rear sway bar with Tecnas, not even our 14mm rear bar.

Front fender liners: The standard front setup provides enough bump travel for a 205/50/15 tire on a +36 offset 15×8 to just barely kiss the fender liner at full bump. Wider tires or lower offset wheels may require removal of plastic inner fender liners in front. If running 245/40/15 tires or touching the front fender liners on big bumps, add our shock mount spacers or travel limiters to create enough space for your oversize tires.

10 year limited warranty against materials, defects, workmanship. Free replacement shock for leaks for first 5 years. Prorated after that.

    Excellent coilovers! Replaced an “entry level” set that the previous owner had installed. I went with Touring spring set due to being a daily driver. I’m not sure what else you would want from a set of coilovers. Excellent handling, excellent comfort when driving. I’m very pleased with them!

  2. Flushdontwork (verified owner)

    Great product. Straight forward installation. The Tecna’s bring out the best in my Miata. I can confidently take corners without insane body roll and highway cruising is a dream. I used the Street Alignment specs after installation of the coilovers.

    First, call out to 949 team for outstanding service and guidance throughout spring selection and setup guidance process. Installed Technas with sport springs on 2004 Mazdaspeed Miata. Night and day upgrade from stock MSM Bilsteins with only 16k miles on them. Ride quality even with sport springs is not stiff / jarring at all and much more active, yet controlled over uneven surfaces. Unless you have a really light build, can’t imagine why sport springs wouldn’t be the right choice.

    Amazing quality at this price point for a custom designed coilovers for our Miatas!
