which JIC coilovers are ideal for drifting? and which is for street/semi drift? thanx

Sorry to hijack your post. I've been also wondering about the JIC coilovers. Do they have any damper adjustment? How well do they handle and how well do they ride? The diagrams on autoimaging.com don't say anything about that. It's basically, "here's a perch, here's the spring, here's the shock, and here's the pillow mount. Yay, coilovers." =/

So basically....
Damper adjustment? Yes? No? What settings? Would it require removing the coilovers each time to adjust them?
Spring rates?
What's the quality? Will they rust like Teins?

its cool...but i didnt know teins rust? like form weather or quailty? i saw 2 replies, after readin urs i was hopin for someones answer, but it was a double post..lol...its cool

Well, from weather the Teins I've heard had problems.  Don't take my word for it, the keyword is "heard".  I haven't seen for myself nor have I seen enough testimonials to confirm this.  The Teins have excellent quality at a decent price ($1200-$1300 without upper pillow mounts), however I've heard "some" negative comments about the ride quality with the HA's.  However, that's expected for any coilover system with that stiff of a spring rate.  If you want excellent handling, you gotta sacrifice SOMETHING right?  Anyway, sorry to hijack your post again.  As far as I know, JIC's have progressive spring rates while the Teins have linear.  I'm honestly not quite certain on how progressive spring rates work, but I do assume depending on how the weight is shifted, the spring rates change on each spring (ASSUMING).  Linear spring rates have a constant and solid rate it stays at no matter what.

*shrug* I'm still learning about coilovers and springs myself. So if anyone's willing to enlighten any of us, by all means, do so. ^_^

It doesn't look like a progressive spring... but the info I get from some of the JIC ads says it uses a progressive spring.  Here's the breakdown AFAIK:

SF-1:
Non adjustable ride height (from the lower mount)
7kg/5kg springrates
FLT-2:
Adjustable ride height
8kg/6kg springrates... i think
FLT-A2:
Adjustable ride height
Adjustable dampening
8kg/6kg springrates

The SF-1's seem better for daily driving, since they have lower springrates.  JIC offers other springs though, IIRC, and you should be able to have custom made springs since they seem to have standard 60mm springs.

JIC's website lists springrates from 3-14kg/mm as 70, but I'm not sure what currency, let alone if that's for a pair or not.
(they even have 16-28kg/mm springs for 80)

They also sell sleeves to convert standard type shocks/ struts to coilovers.... those retail at 160.  Pretty interesting.

posting yet again... it seems those figures are US dollars... I just browsed into the LSD section and it lists the 240sx, not a Silvia, which (with the listing of a 2.4L engine) leads me to believe I've stumbled onto JIC's US site.
