Included adjustment knob dials ride from SOFT to FIRM by just turning in the direction of arrows on the knob. That allows you to dial it soft for daily ride and firm for autocross and canyon and track fun, or any point in between for your ideal compromise of ride and handling.
KONI has a long-standing reputation in racing circles as a manufacturer of high performance, top quality shocks and struts. KONI uses superior materials in the manufacture of their components to ensure significantly improved handling and excellent durability. Designed specifically for the 2016 Mazda MX-5 application, these externally adjustable shocks will improve the handling performance of your car!
INSTALL NOTE: Shock Rod is 12mm, stock bump-stop washer is 10mm, so you need to drill out the factory bump-stop washers slightly for install.
Picture shows that clip ring has multiple positions, allowing lowering even with stock springs:
Price is PER shock, if you need two, order two!
BRIAN'S APPLICATION NOTES: KONI has long been a strong choice for street customers seeking an adjustable shock and track/autocross customers competing in 'street' classes. We run what we sell, we have these in our 2019 ND2 Miata for SCCA CS Class Autocross. Watch autocross below where we took first place in class and Top Pax out of 122 competitors for the event.
Thanks to Brian's recommendation. I have these KONI front/rear Shocks with GWR Bump Stops, GWR front Endlinks/SuperPro rear Endlinks, front GWR tower brace, and Progress Tech Springs. My first AutoCross, I dominated all N/A and Turbo Miatas (I am on ND2, no tune). I couldn't be happier with GWR's expertise in GWR.
The installation is same as installing springs with slight modification using a Dremel tool. I grinded off the Bumpstop top hat off about 2mm in order to have them fitted. The lowest perch was way too low for me, and so I reinstalled the whole thing again and set at the middle perch. The wheel gap was eliminated and height was good enough to clear most driveway going diagonally.
The ride is slightly rougher but nothing unbearable for daily driving. I wish the adjustment has clicks that you can actually feel, rather than analog.
Overall, I think it's a good buy. if you want to upgrade your suspension component one at a time.
