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).

The wait is likely due to requesting such a specific set up. Mostly luck; i bought a set for my IS300 during a black friday sale when they had a bunch of un-sold stock leftover from whatever their last production run was. saved a few hundred bucks

best part - they actually screwed up their inventory system, my order was listed as in stock but not in stock. They built me a new set with the latest version of parts and honored the discount price. lol

If you wanna be baller you should get their Air Piston lift system too.

Fortune's customer service is fantastic however I wonder about their calculations when it comes true type setup on our cars. Do your homework and or get help!

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

Spooler from reading OZ link I do think I need to go with 7kg/mm or even 6kg/mm

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

OZ thanks for the link, I am still reading it over and over as there is so much information in there but from what I was able to understand till now it looks like i need to go with front 14kg/mm or 13kg/mm and rear 7kg/mm or 6kg/mm.

I don't have any aftermarket aero only the Nismo wing and lip that came with the car and the back of the car is gutted. Adding aero
and gut the front (100% stock today) are things that I will do one day, but when I will do them I will also need to change the spring rates.

What do you guys think about these numbers?
