would suspension from 3rd gen fit onto the 2nd gens?
yes and no
For the front, you will need the forks from DC/EG. The back is a bit more complicated. You cannot use the stock or aftermarket DC/EG shocks, the length is different…unless you switch over to the JDM style rear lca (box type), in which case you can use the ITR shocks for the back.
