D40 or D22?
D40 you can add strut and diff spacers. But remember the higher you lift the less down travel you have.
If you want to go higher there are products out there and in the states that will give you 3" lifts, up too 5" lifts. Just have to do your home work.
Height Adjustable struts are good as you can set the height you want and can go up to about 3.5" lift. You may need to change your upper control arms if you want to go over 2". Don't have to but might hit top strut hanger.
Anyway there's a start for you.
