What length coilover springs for NB shocks on NA
 

Decided that rather than cobbling together a way to fit NB mounts on NA shocks or blow $285 on FCM's solution I'd just sell the NA shocks and get NB shocks.

I'm still going to get FCM's MCU bushings for the mounts, but those are only $60.

Going to get an ebay coilover setup and use the sleeves with some quality springs.

So what length springs do I need front and rear? Thinking 350 front, 250 rear if that matters.

What shocks? Where the ebay sleeves sit will depend on what shock they are, which in turn decides what length springs. And, what ride height target?

NB Illuminas.

Was planning on following the suggestions in MX-5 Miata Forum - The Quintessential Ebay Coilover Thread for ensuring the that the collars seat on the bottom of the shock.

Targeting 12.5f, 12.75rear.
