Does anyone know if a set of MSM bilsteins will work on a NA with racing beat lowering springs?

 

An MSM Bilstein will work on any car (NA or NB) provided that it is fitted with NB-style springs and NB-style tophats.

You cannot use NA-style springs or tophats on an NB-style damper, or vise-versa.

As an assembled unit, any homogeneous shock-spring-tophat package (NA or NB) will fit into any car (NA or NB).

 

*without collars or a flat style mount


Luckily the spring perches on the Bilsteins are removable/interchangeable. I'm pretty sure I have a set of NA (d'oh...NB) (angled) perches sitting around the garage for Bilsteins.

 

Huh? The NA perches are flat. It's the NB ones that are cut at an angle.

 

Sorry, between reading his post, writing mine, and trying to figure out if what I had would help I got lost...

You are definitely right...NBs are angled.

The ones I have are also definitely angled...and won't work in this case. I was hoping I also had some flat ones, but I don't. These can be pretty easily made, but it's easier to just go to collars and 2.5" ID springs.

 

I think i just posted the same question.
Does msm mean miata speed 99-05?

 

Technically, MSM is MazdaSpeed Miata, which refers to a specific set of cars built in '04 and '05 which had sparkly paintjobs, small turbos, and a few other options. They were all equipped with Bilstein shocks, however this shock was not exclusive to the MSM, it was available as part of the "suspension package" or "sports package" on all NBs with manual transmissions.

The Billies which came stock on these cars differ in one very significant way from the ones you can buy brand new for $93 for any Miata- they are painted silver.
