Qqun sait si ça se monte sur foz 2003/2004 et sur 2006 ?? Peut être juste les coupelles ar à revoir ainsi que les éventuelles cales sous le berceau...

jean-david a écrit :justement c ce que j'ai, le gas a qui j'ai acheter le foz a tout recup de la sti des freins en passant par les demi train, moteur, boite, faisceaux moteur et habitacle... etc...
peut tu me donner plus d'infos sur les pieces dont tu parle qui differes entre forester et sti ?

Toutes les pièces que j`ai citer, sont différentes .... l`ensemble moteur/boite étant plus bas que la normal sur le forester, ces éléments ont une forme/longueur/fixation différente, afin que l`ensemble soit aligné et fonctionne correctement

l'adaptation au niveau du radia est pas des plus simples ca c'est clair, le faisceaux habitacle ca doit etre un gros morceaux aussi.... mais le reste a pas l'air tres compliqué a adapter...

je ferait des photos si ca peut aider certain dans leurs modifs

autre point important, si je veux pouvoir tracter un plateau avec la gt dessus, ce ne sera pas genant d'avoir des combinees filetees ? il ne risque pas de s'affaisser de l'arr ? y a t'il des modeles d'amortisseurs specifique ? (du genre les Tein superwagon)

jean-david a écrit :Parceque les superstreet que j'ai sur ma GT ferait d'être remplacer car usage full piste maintenant...
Donc comme ça j'investis dans de bon amortos pour la GT (et je recup les superstreet pour mettre sur le forester)

If you are looking at swapping Impreza struts on to your SG Forester (03-08) PLEASE read this carefully.
***If you are interested in installing coilovers then the ONLY thing you need to know is that any 02-07 WRX coilovers will bolt right up to your Forester, no spacers of any kind needed***

THESE ARE THE ONLY POSSIBLE SETUP CONFIGURATIONS SO THIS IS YOUR PARTS LIST
Possible Setup Configurations:
02-03 WRX fitment struts
02-03 springs
02-07 front strut mounts
02-03 rear strut mounts
saggy butt spacers
.................................................. ............
02-03 WRX fitment struts
04-07 springs
02-07 front strut mounts
04-07 rear strut mounts
TiC Scooby921 spacer
saggy butt spacers
.................................................. ............
04-07 WRX or 04 STI fitment struts
04-07 springs
02-07 front strut mounts
04-07 rear strut mounts
saggy butt spacers
.................................................. ............
05-07 STI fitment struts
04-07 springs
02-07 front strut mount
04-07 rear strut mount
structural modification to lower mounting holes (drilling holes to fit 5x114.3 hub)
saggy butt spacers
.................................................. ............



Top Hats
This is where the most confusion is had for the strut swap.

Fronts: 02-07 WRX/STI and 03-08 Forester (they are all the same fitment)

Rears:02-03 WRX rear top hats are different from 04-07 WRX/STI and 03-08 Forester rear strut mounts.

***If you are swapping any 02-03 WRX rear strut into your SG Forester and are using 04-07 springs and mounts you will need the Scooby921 strut spacer, for your rear struts only, made by TiC.***If you do not buy the spacers then it will result in damage to the strut and eventually catastrophic failure. They simply sit on the strut shaft and keep the mount flat when installed.

These spacers are necessary only when using 04-07 rear strut mounts on 02-03 struts. If you are using 02-03 strut mounts you can simply use 02-03 WRX rear springs.



Springs
Fronts: You can use any 02-07 WRX or STI front springs as they are all the same throughout these years.

Rears: 02-03 WRX rear springs are different from 04-07 WRX/STI rear springs.



Struts
Any 02-07 WRX and 04 STI strut will fit into a SG Forester with no modification.
If you are looking to install 05-07 STI struts then structural modification to the lower mounting bolt holes on the strut will have to be done due to the hub difference. (5x100 to 5x114.3)


Strut mount spacers:
These are completely different from the Scooby921 spacer listed above.
These are used to lift the body of your vehicle off of the strut top by a specific amount. When using WRX or STI struts a 3/8" spacer in the rear is the most commonly used with no spacer in the front. This is due to the struts being designed for sedans as opposed to our heavier Forester SUVs.

Here's the math (1kg/mm)*(25.4mm/1in)*(2.2lb/1kg) => 1 kg/mm = 55.88 lb/in

For quick reference:

5k = 279 lb/in
6k = 335 lb/in
7k = 391 lb/in
8k = 447 lb/in
9k = 503 lb/in
10k = 559 lb/in
11k = 615 lb/in
12k = 671 lb/in
13k = 726 lb/in
14k = 782 lb/in (yes, some people actually use springs this stiff)

What's lb/in? What's kg/mm? What's the difference?

Lb/in and kg/mm are different ways of measuring how stiff a spring is. lb/in is how many pounds are necessary to make the spring compress one inch. A 100 lb/in spring with 200 pounds of weight on it will compress 2 inches (assuming there are two inches of travel). kg/mm is the same thing, but metric, like they use in Canuckistan. More info here:
http://forums.nasioc.com/forums/show....php?t=1083184
Rule of thumb'ish: Divide lb/in by 55 to get kg/mm. Multiply kg/mm by 55 to get lb/in.
