Flyin' Miata spring set (ND/Fiat chassis)

Flyin' Miata springs are well-known as the best springs available, no matter what Miata you have. Our springs for the ND are no different!

As always, we started from scratch. We set up our cars with custom coilovers and started testing ride heights and spring rates. Then we started winding prototype springs so we could test the real thing. Testing takes place on the track and on real roads. It's a long process with the constant testing and feedback, but it pays off. It's why FM springs are the standard.

Soft top springs:
Front 300 lb/in, 13" ride height
Rear 175 lb/in, 13.5" ride height

RF springs:
Front 300 lb/in, 13" ride height
Rear 205 lb/in, 13.5" ride height

The end result is a good balance between spring rate and ride height, giving you enough room for everyday clearance and still being able to absorb bumps before hitting the bumpstops. We've known for years that running a soft spring rate with a lowered ride height is a recipe for disaster as the car slams into the bumpstops, so we always run enough spring rate to prevent that. It might seem counterintuitive that a stiff spring will be more comfortable than a soft one, but it's true.

We recommend using a set of our MCU bumpstops in the rear with these springs for best results. Front bumpstops should be left stock.

We have tested them with the stock 2016-17 soft top Club Bilsteins and found it acceptable for both performance and ride - surprisingly good for ride. Those shocks are overdamped to begin with, so we're simply giving them the springs they desire! 2018+ soft tops and all RFs came with a different Bilstein that is NOT a good match to our springs. They work even better with the Koni Sport, which is why we package them together in our Stage 1 and Stage 2 packages.

Not recommended for the stock Sport, GT or Classica black shocks or 2018+ soft top/2017+ RF Bilsteins. Put another way, if you don't have a 2016-17 soft top with Bilsteins, you'll need new shocks in order to handle these springs. Made in the US to our exclusive specifications.
