Sti 5 used inverted struts doesnt it? would these be a direct replacement for STi 4 suspension?

Also is there a lot of difference between the 2 setups? and if so enough to warrant fitting sti 5 Type R suspension to an STi 4?

Thanks.

 

They will fit, better if you use both the springs and dampers though.

Probably be a bit harder and an improvement over STI 4 Type R depending on their condition.
