Eibach Pro Kit for Mk4 Focus ST Line X - What’s the extra drop?

Hello All,

I’m new to the forum, just joined up as have a number of questions I need to find an answer for that google simply doesn’t seem to be able to help with!

I’ve just purchased a new daily, a 2021 MK Focus ST Line X and want to make a number of minor, but necessary adjustments for my visual taste.

So, my plan is to do the following;

1. Drop onto new springs (I don’t want coils)
2. Replace mirror covers with black ones
3. Replace the fog light covers with ST covers or wrap/paint them to be the same
4. Replace the lower grill with the ST one to match the upper honeycomb grill
5. Add spacers - probably only 10mm front and rear but happy to hear people’s opinions

My first question is! How much EXTRA DROP do you get with the Eibach ProKit over the factory sports suspension? Says on their web site it doesn’t cater for this so you have to minus that figure from their projected drop. I guess I don’t want to spend £300 ish on new springs if they only give me 10mm extra. It says 20-25 front and 30mm rear…so my guess is it’s 10mm drop as the ST line from factory but can’t find anything online to confirm. Anyone have any ideas what it is?

If I can get 10-15mm front and 20mm rear additional from ST Line factory springs with the Eibach springs then I will take the plunge.

Thanks!
