I would second OZ for Fortune Auto, and if it was me, I would go for single adjustment coilovers, which I already did, it is more simpler to adjust and wouldn't need a lot of time to reach your prefered setting.

When you get into coil-overs with multiple dampening adjustments. You can really dial them in for a track, and they will be great. The problem with that is you can really lose your way with them too. Making them totally useless. It takes time and patience to find the right settings. Plus what works at one track, may not work well at another track.

Thank you guys! I think think I will change my selection to something that may be “simpler” but I will work for me and I will get the best out of it!

Is anyone have have info about these?

Someone recommended them to me today but I can’t find any good full review on them.
The guy that told me about them running a different Cusco set and saying he love them.

Do yourself a favor and focus on getting something a little less exotic. Just find a quality single (maybe double) adjustable set of dampers and start there. As someone else suggested, maybe try Fortune Auto. Good dampers have a finite life but normally can be rebuilt. Getting a set that ISN'T exotic means finding a place to rebuild them won't be nearly as difficult.

I'm happy with my Fortunes. OP you would also likely be happy with bc, feal or any of the other entry level brands that OptionZero mentioned.

Gomer is right. If you plan on doing this for a while, the coil-over will need to be rebuilt or you may want them valved for stiffer springs. It is a lot easier to do that when you aren't shipping your coilovers half way across the world and translating emails.

Quicksilvers

I had a set of Fortune 500’s before and I believe they are a excellent quality coilover for what they are a specially when trying to keep on a budget. Just make sure the coilovers you are using are valved for their intended purpose. If you use your coilovers for what they were built for look toward to rebuilding them.

For anyone with a $2,500 to $3,000 range budget, I would suggest the KW v3 coilovers if you are ok with a divorced spring setup.

All feedback i've seen is that the KW V3's are not stiff enough for track use, AND there is limited height adjustment. Seems like purely a street coilover for someone that doesn't want to be low

also, no pillowball mounts, rubber only. poop

you can do better for the price (and frankly i think you got the price wrong)

for 2.5-3k you are getting into Aragosta/AST territory, which is miles better

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.

OptionZero

Yup, spooler is right. Your spring rates are appropriate for a divorced spring (OEM type) setup; when you change to true type the geometry change and you need to adjust the spring rate accordingly

Call Fortune immediately before they lock in your order

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.
