You can buy the number 4 ones right now brand new from Japan, off the shelf if you were in Japan or know someone in Japan.
They are called "Earnest Product" made by B-Crews.
If you know someone in Japan, they can order you a set by ringing the store.
They are the ones on my car. Very happy with them indeed. Absolutely great feel to the car now with these. Extremely firm/controlled damping, but still the ability to absorb bumps very nicely. They absorb bumps smoother and more controller than micra adjustable konis on stiff setting, yet the car is lower and doesn't roll as much. Brilliant I reckon.
Standard spring rates are 5kg at the front and 4kg at the rear, they have larger ones in stock on the shelf most of the time, but 5kg/4kg is what I run, and its perfect for the street. The car definately is not harsh/rough.bumpy etc, i.e. I don't hit bumps and cringe..
The upper ball joints in them are a bit stiff, so sometimes the steering has a bit of a memory to it. I.e. if you've taken a very tight turn, it kind of sets the bushes to make the steering pull to the left very slightly. But the next right hand tight turn makes that go away. I asked him about it, its just the way they all are, because of the new much lower geometry and strength of the ball joints required. The factory struts don't have upper ball joints, but the coilovers do so the geometry works. I hardly notice it though, and its only sometimes.
The shocks are the largest diameter of any of the coilovers, they are huge in real life. I think that's why they have so much control even at such low heights. They are about 16 point adjustable I think. I.e. about 16 defined click settings to make them firmer or softer. I only use them on the softest setting, so you could make them very firm if you planned on heading to the track or anything which is a great feature.
They are also totally adjustable in the car, even the shock settings etc. Unlike the micra rear adjustable konis which you need to remove from the car to adjust.
After sales service with B-Crews is second to none also. He will really look after you and answer any questions you may have at a later date.
