My Missus is ordering me a set of Eibach Pro-Kit springs for my Focus for Christmas.

However Eibach have two types listed for my car. They have identical drops and are both for hatchbacks but have two different front axle loads.

This has a front axle load of 985kg...

This set has a front axle load of 1100kgs...

How do I tell which one I need for my car?
