NB suspension on an NA.
 

What parts are needed to use the shocks and GC coilover sleeves from an NB on an NA? Is it just the NB top hats?

A friend bought a set of Koni w/ GC sleeves and springs that were supposed to be for an NA, but the part numbers on the Konis show that they are for the NB.

there are the NB top hats and all the components that go with that, bushings, washers etc. IIRC it'll cost you under $20 per corner if you get the parts from MazdaComp.

If you want to my opinion better bushings for the top hats, go to autozone and get a set of energy suspension sway bar bushings. The box comes with 8 I think. Then drill the hole larger so the shock rod goes through and cut each bushing in half. It works good, we've done it in 3 Miatas with no problems

you can't REALLY use NA shocks with the NB but only because the shock shafts aren't long enough to reach all the way through the NB mounts.

PS nice that my little graphic is making the rounds ;)

Here's why the lengths are important:

Notice how the NA shock shaft ends well below the top of the NB bushings...

but he was asking the other way around, NB on NA.

thought i grabbed that gif off FatCat's site. It's been a few years.

oh duh. yeah if he's got NB shocks and NB mounts then it's a slam dunk. the only issue is that you lose about an inch of spring height if the springs they sent are for the NA.

I think I made that pic back when shaikh was just starting out.
