Looks like you don't know what you want exactly, Cusco is a great company, but you may not find support locally, specially when it is time for rebuild, and most JDM parts are overpriced in US.

Living on the other part of earth, I faced this issue, I had Zeal Function coilovers, they was a great set, but I had an accident and suspected they may be damaged from the impact and wanted to get stiffer springs, couldn't find any local dealer (which apply for all brands here

) and shipping them + service costs + shipping back was nearly as much as new set of coilovers, I sold them for cheap, and bought a new set from MCA with custom springs and valving.

Fortune will be local to you, so you can save a lot in shipping, also, their coilovers are upgradeable, so if you got 500 or 510 series, you can upgrade them to 2-way or 3-way. They have a lot of great reviews and many members using them here.

At the end, the most important in coilovers are the shocks and valving.

Also, you need to be wary of spring rates with true type coilovers.

This is a great point. I have called Fortune and talked with them over the phone. They recommend to go with the 510 and upgrade to swift springs with 13 and 9 springs in front and back.

They also gave me a great price, I wish it did not take 4-5 weeks to ship lol. I am getting the founds and will go and order them.

A 9kg/mm spring in the back on a true coilover is probably too much. I would look at more in the 7kg/mm range.

I think a 7k true is about equal to 11-12k OEM type right? So that would probably match 13k front better

4-5 weeks is not a long time to wait on parts. Wait until they tell you 4-5 months.

Think you made the right choice with the Fortune coil-overs.

I agree with others, rear is stiff, I would say 5kg or 6kg if you don't have a wing. I have 21kg/7kg and it gives a good balance with some play between understeer and oversteer (depends on how much rake I have).
