i'm sure klue is right. hell the majority of the suspension is different. i know the front struts are different for stock stuff but i think in some aftermarket applications they can be made to work. esracing would know a little more on this.
I have 5gen adjustables in my gt4 and the only thing i noticed was a slight difference in the sway bar mounting height maybe 5mm. I'll have a good look at the ones in my parts car when i strip it down and post a pic or two.
