Koni Sport shock and bumpstop set (ND/Fiat chassis)

KONI ND Suspension with included hardware
Koni Sport shock and bumpstop set (ND/Fiat chassis)

One of the classic Miata shocks for the latest platform. Now includes a set of improved rear bumpstops for better ride and handling.

Availability: In stock



The Koni Sport has been around the Miata world for decades, and now it's available for the ND! 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.

Now includes a set of new rear bumpstops - a $45 value.

The Sport has adjustable rebound damping, allowing it to work well with stock springs as well as stiffer units. They are adjusted via the top, no there's no crawling around on the ground.

Due to the large shaft size used by Koni, you will have to drill a larger hole in your bumpstop support washer. New upper washer and crush tubes are included to make installation easier.

Available as a package with Flyin' Miata springs.

Great for street and everyday drivability
Haven’t autocrossed yet but on the softest setting they are very comfortable for the street. Some modifications are regrettable when your car is used for daily commuting. No regrets with this.
Although pretty easy to install I think the instructions could have been more detailed. There are two similar looking washers one which you replace and one you drill out and reuse. I think I got it wrong. Also I overdid the loosening of the A arms and put my alignment way out of whack. Maybe a little more detail on those two steps would have been nice. All worked out and easy to finish in a few hours.
