You have some choices, depending on how high you want the car to sit .

If you want it to sit 25mm higher, use 2wd springs ref: 30-026, this is the standard ride height springs for a 2wd.

If you want to raise the height by 50mm, use the standard ride height springs for a Sapphire 4x4 - ref: 30-029

All of the above is assuming that the springs supplied and currently fitted are in fact the 30-025 (-25mm 2wd items).

This is why you really need to fit matched springs and dampers, as AVO have pointed out, different dampers have different body lengths .
