DO you mean Bilstein? Well I think any brand of lowering springs will fit. Apexi, Tein, king etc...

Brand doesnt really matter. It is all about what spring rate you are using. Higher the spring rate, the stiffer the ride will be. I think something around 8-9 kn/m and 5-6 at the back is comfortabel

No, that will be really hard i think. I thought the lower the number the softer they are. mine are about 5 and they are stiff. so go down to a 4 or 3 or even 2

Guys c'mon...

Get the eibach springs. Good shiz. Even Bilstein dealers at heasman will recommend the eibach springs (really well made and good performance, and are cold rolled) on their bilstein shocks.

As for spring ratio, that's a hard call. Depends what you want ? Want to compromise a bit for less roll and better feel/handling - go 6 front and 4 rear. Want more comfy but also handling - then go maybe 4 front and 2.5 rear and get some thicker swaybars front and rear to cancel roll.

Tires will be a consideration too for handling and comfort. If you got low profile tires...might wanna consider a softer spring rate as the tires won't absorb much but won't flex much either giving a good driving feel.

I'd call Eibach themselves and get a part number if they have one. I'm not a 100% sure they do though but they're warehouse is in sydney.

Here try this
http://www.eibach.com.au/eibach_partners.html

Just call them and they'll be able to tell you if they have fto springs or not. If not, there are a couple of other spring companies that are really good quality too but i forget the names atm. Google will show i'm sure.

Your 40 profile tires are fairly low already...so you might consider the more comfort oriented range from eibach, else they've got the sportier range as well... i still wouldn't hesitate running the sporty range on 40 profile tires though.

Kg/mm is basically how strong the spring is. Higher the number, stronger it is.

Goodluck! Swaybars is an awesome consideration/addition for the fto btw if your spring/shocks can't offer enough vertical load resistance to cancel roll (e.g. when you've gone for comfort oriented equipment).

My front springs are Eibach. They made them for me specifically. Give them an old spring which gives you the height you want, then tell them the spring rate you want. I think mine were 3.4kg/mm or something... I cant recall, its in another thread here somewhere. Eibach are the goods, cold rolled too.

oic...is that's mean eibach don't have any spec for fto ? or they can also do custom made ?

Yeah, was about $200 spring. They can make springs to suit anything. I never got round to talking to their marketing people to see if they actually wanted to run an FTO spring "off the shelf"

contact with a eibach dealer , they ask me use proton spec lower spring , it's similar to fto. the model is 6105-140. any ideal...

finally find out the spring rate , it's 35n/mm ( front ) & 28-53n/mm ( rear ). it's that suitable ? thanks
