Въпросът ми става ли предна пружина от Импреза 96г. за Легаси от същтата година и ако да това оказва ли влияние върху поведението на автомобила

Да стават, но само предните.

За твойто Лего стават също и пружини от някои Импрези 02-07 GD, в случая и предни и задни

2.Will STi struts and springs work on my car?
Yes, but only '04 STi struts will be a direct fit because in '05 the hubs were changed from 5x100 (which is what your car is) to 5x114.5. '05-07 STi springs will work too, but also require the '04-07 top-hats. Additionally, any '02-07 WRX set-up will work since the WRX never changed away from the 5x100 hub

3.What about WRX struts and springs?
As stated above, yes they will fit. Any '02-07 WRX strut, spring and top-hat combo will work on our cars. These will only lower half an inch at most with the stock WRX springs.

4.I've heard wagon and sedan rear struts are different, won't you get 'ass sag' with sedan struts in a wagon?
Generally it's chassis related. In most cases, second gen. Impreza (bugeye-hawkeye) suspension works just fine in our second gen. Legacy wagons and sedans. The exceptions being the 05-07 STi struts which don't work due to the different hub. GC/GF (first gen. Impreza) stuff also works in Gen 2 Legacy's, but GC/GF Impreza rear shocks and springs are shorter, and so you get the 'ass sag', regardless if it's from a wagon or a sedan

8.What are you running on your car? (Legacy ‘95-‘98 BD/BG)
I currently have '04 STi struts with '05 STi springs, a 22mm adjustable Whiteline rear sway bar, Tribeca 25mm front sway bar, Kartboy solid front and rear endlinks, Ingalls camber bolts on all four corners and a slightly aggressive alignment (-2.3 degrees front camber with zero toe and -1.4 degrees rear camber also with zero toe).


ok here i will log all my findings about what fits what on what and who along with when and where.(just for confusion)

ok so for those with no swap the tophat to make work.
this is for installing Impreza suspension on Legacy's only. if we add any more models this could be confusing.
model---fit front? fit rear?
05+ STi is a no go for all models..
