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?

 

Have a look on your weight plate, top number is gross vehicle weight, next is gross train weight (for towing so not all will have a weight listed). Next is front axle max, and last the rear axle max.
I would hazzard a guess that the higher rated are for diesel's, but your plate should give you a goid idea.

My plate says 980kg. I would probably hazard a guess that I need the 985kg springs then?

 

I would of thought so yes.
