Looking to replace my subaru supplied prodrive springs (Eibachs) with whiteline flatout springs.

The car is an 02 bugeye wrx wagon. My question is:

The part number for the front springs are the same as the saloon but the part number for the rears are different but are the same as the whiteline control springs on the saloon.

Can anyone shed any light as to the reason for this and if the flatout rears for the saloon would be ok to use on the wagon.

The only reason I can think is that the wagon is heavier at the rear than the saloon.

 

If you fit saloon springs to a wagon you'll end up with unsighly rear end sag due to the heavier weight at the rear of a wagon.

Some springs (like the PD blues) use a single spring, in which case you'll notice that a saloon will sit slightly tail high by about 10mm.

Flatouts are the same spring rate as controls, just lower, so I can see that WL would save money by using the control rears from a saloon on a wagon and the lower flatout fronts to get the front to match the 'already sagged' rear!
