One of the classic Miata shocks. Now $130 less expensive! Includes a set of MCU bumpstops.

Availability: In stock



The Koni Sport has been around the Miata world for a couple of decades. They are exceptionally long lived with a lifetime warranty for the original purchaser. One of the fastest off-the-shelf shocks you can run in stock class autocross. We're bringing it back into our catalog to go with our suspension kits.

Includes a set of our improved MCU bumpstops - that's a $60 value! Only from Flyin' Miata.

The Sport has adjustable rebound damping, allowing it to work well with stock springs and stiffer units. Not recommended for use with stock MSM springs, as that can lead to uneven ride height front to rear.

Available as a package with Flyin' Miata springs.

Note: The Koni shocks have a 12mm shaft whereas the stock shaft is 10mm. You'll need to drill out the two washers on the upper mount to accommodate this. It's not a difficult task.

Great results on otherwise stock suspension
I have an NB with 150k miles, original shocks I believe. Well until I put these bad boys in. Install took me about 6 hours. Drilling the washers out was simple enough and I used a jack to slowly lower the stock coils so a spring compressor was unnecessary. Once everything was in and I got an alignment, I cranked them to full stiffness and took them for a spin. On the freeway bumps were more pronounced but nothing I couldn't live with. Then I took it through the canyons. To say my car was transformed is no overstatement. Where I used to have to baby it through the corners to not upset the chassis, I was carrying 10-15 mph more than before. The grip was very confidence inspiring, the front end had more bite than I could explore on a public road and the back was very controllable.

These shocks made more of a difference than I had hoped for. My favorite mod so far and easy to do yourself. Be aware that at least in my case they seemed to raise my ride height just a bit.
