From the reasearch I did, the concensus in the Miata world is not to chop springs. The spring perch design isn't as chop-friendly as the Metro's design (I am VERY pleased with the results on the Metro, with 50% more drop).

Thus a fairly conservative drop of ~1 inch on the Miata. I did it in 2 stages to ensure I didn't go too far on the first cut. The springs are still under compression (though not a lot) at the point of full suspension travel.

I haven't driven it much yet, but a quick spin didn't feel dramatically different.
