Can anyone confirm me what's the spring rate do JIC flta2 come with. Some said 10f/9r and I saw a post by vivid racing saying 9f/ 8r. I just got mine today, and on the box, it said 8f/ 9r?? Any one know?

 

8 kgs = 447.6 lb springs
9 kgs = 503.6 lb springs

there ya go!

 

Thanks ogvw, but what I really want to know is what's the standard spring rates of the JIC FLta2 coilover front and rear off the shelf? 8kg front and 9kg rear seem odd because most of the JDM coilover came with stiffer rate in front compare to the rear out of the factory.

 

10K Front 9K Rear - That's what the box from my set said.

 

JDM Spec is:
Front 9
Rear 10

There're TWO sets: one Front9 Rear10, the other Front7 Rear7

 

Seems like everybody got different spring rate.... My saids 8kg front and 9kg rear on the box.

 

They are 10f/9r. We sell them and we just installed a set on Wojo's car this past weekend.

The rates are imprinted on top of the springs, where they are flat and sitting against the top perch.

 

You are the man. now I can verified my rates are 8kg F and 9kg R. Just the way I want it. I hope with a stiffer rear rate will helps the car rotate better. Thanks again. Strange that JIC have all these different rate out of the box though.

 

They do not have it "out of the box". But they do have several versions of shocks built and they match the springs to them after you specify few details on how you want them customized

They are just out of inventory for the Evo ones as the new 2004s are coming in March. cough..cough with a slightly higher price but no technical changes we are told as of yet.

 

Mine came with 9k/8k.

 

How long ago did you purchase them?
