I have an 83 528e that seems to be lowered but the owner didnt have any info about how it is lowered and I haven't taken a good look at the components.

However, it does have one set of Front H+R 50413 springs for an e34 as well as a set of Rear H+R 50428 springs for an e28. (Sitting in a box)

Is there a reason for someone to buy two springs meant for an e34 i stead of the whole set meant for an e28?

I would like to raise up the car slightly as it will be driving in an arctic climate with snow drifts and will need some beefier tires so I am trying to figure out how I can utilize these springs for a higher ride.
