I just picked up a 99 NB to replace my 90 NA miata and i wanted to see if anyone knew if my aftermarket NA suspension parts will fit on my NB and vis-versa.

Flyin Miata stage 2 suspension with ground control coilovers & AGX adjustable dampers

Flyin Miata front and rear sway bars

Also have a PWR radiator i wanted to move over.

Thanks in advance guys

 

You have not called FM's tech support line why? Post answers after you do.

 

I crashed my '99, bought a '94 and swapped over my BC Coilovers, RB Swaybars, and RB Endlinks. I know a lot of companies show different parts for 90-93, 94-97, and 99+ but mine swapped over without any issue at all.

 

Shocks and sways transfer between NA/NB. The parts are different but they all fit eveywhere.

The radiator is totally different.

 

If you do this, I think it's important to also move the NA tophats as well

 

Talked to Keith at Flyin Miata (awesome guy with great customer service)

This is going to get confusing:

NB coilovers will go to a NA miata with no issues.

NA coilovers will not easily convert to a NB. The ride height on NB with NA suspension will be around 1" lower than the NA with the same suspension.

The sway bars from the NA should work with end-links but the angle of the sway bars differs between the two models thus changing the leverage of the bars and thus effecting the over all function.

Radiator mounting points are different between the two so i will just make my own mounts.


Hope this helps someone down the line.
