I made so much fuss about buying these springs and changed my mind a few times - cancelling one order and returning another set unopened (i was worried about increased insurance and scraping on speed bumps).
In the end I couldn't resist having them fitted (by Mx5 parts) and am delighted with the results. The car looks much better and the handling has improved dramatically. A few months prior to fitting the springs I had a 4 wheel alignment carried out at WIM. This improved the handling considerably and I decided that the alignment was probably responsible for the major gain when lowering and aligning an mx5. Now that I've fitted the springs I would say that both parts of the package play their part and the car has taken another leap in terms of handling and feel. Turn-in is so much better and the car feels more agile and has less body roll. I have read concerns about the car being under-damped with these springs and the standard Bilsteins (on my 2.0 Sport). I did notice some bounciness from the rear on a fast, bumpy A road on one occasion but the overall gain far outweighs any disadvantages. Speed bumps have been fine but I've been slowing down more than before, so no scraping. My insurance didn't charge any extra when I told them about the springs, either.
I've yet to drive the car on a track but can't see how the car could be anything other than an improvement over stock. Coilovers were overkill for my needs as I don't drive that fast generally and only do occasional trackdays.
