Fortune Auto Coilovers: 500 series
Cost: $1000 shipped
My current ride height:

I can still go much lower in the back and about 1 1/2" lower in the front if I pull collars
Ride:
The ride is pretty comfortable. I'm using the recommended 7k/6k spring rates and the first time I drove around with these, I put them on full soft and it bounced around a bit, that was fun for a while but I wanted a more solid ride. I turned the stiffness up by 3 clicks all around and that was a good balance of stiffness, it absorbs the bumps nicely and doesn't slosh around like it did on full soft.
The ride was slightly harsh for the first few months, but now the coilovers seem to have settled in and the ride is quite good for being coilovers.
Quality:
Of course with most $1000 and lower coilovers you will never get a high performance shock absorber, but Fortune Auto put in a great effort and I think these are one of the best deals around.
Unlike most coilover companies, Fortune Auto put the shocks on a shock dyno to make sure that all 4 shocks work the same and perform the way they should, and that the soft/hard clicks on the shock actually do something, unlike Megan/Godspeed/etc..
Here's a neat graph provided by Fortune Auto:
It's not as smooth as a high end shock but hey, the clicks actually do something
Compared to some Ksport shocks:
Look at the variation between the max setting on one shock and the max setting on the other, they should be the same, but they are way different, that is bad.
Feature I like:
As an added bonus on the FortuneAuto coilovers, they come with a nice black anti-corrosion coating, I thought they might scrape off when I adjusted my ride height but they never did and I'm really quite impressed by the quality of the coating.
Overall impression:
My S13 is my daily driver and I drive it everywhere, my previous setup was some KGB shocks + lowering springs and I did not want a ride any harsher than that so I made sure to pick my coilovers carefully, and I think I made a great choice.
I'm quite impressed by the ride quality of these coilovers, I would say that these are on a similar level of comfort as my previous lowering spring setup and I'm real happy with it.
Also, the coilovers don't squeak or make any other weird noises so on the freeway so that is also a plus.
I would definitely recommend these coilovers to my friends or anyone that wants a ride that won't break your back.
