Thought I'd share my experiences with Eibach lowering springs in the hope it helps some of you out there considering this modification. Let me start by saying in my opinion the M135i is lacking that little bit of X factor as standard. I initially had the car on the 19" 557m wheels & felt it just lacked that sporty look I was looking for. Initially I decided to change the wheels & add some M performance bits but I still felt the car didn't look right. So eventually went for the Eibach lowering springs.
First of all… in my opinion had I done this modification first, then I wouldn't have bothered with the wheels & the M performance parts. It is the lowering springs what really take the look of this car & the driving experience to the next level.
There are two kits that are in general use on the M135 as below:-
The official M135i Eibach catalogue kit, part no E10-20-047-03-22. This kit contains front springs F11-20-030-03-VA & rear springs F11-57-005-01-RA. This kit gives the official drops of 30mm front & 15mm rear. In reality this kit dropped the front closer to 4cm & the rear by the stated 1.5cm & having spoken to a few other users this seems consistent. I fitted this kit with 10mm spacers all round. Looks wise this kit gives the car a much more aggressive nose down stance with the front arch gap looking slightly tighter than the rear. In terms of the driving experience this kit was superb, the car feels incredibly planted, soaks up bumps well & doesn't get unsettled across bumpy road surfaces. The turn in feels sharper with very little body roll. No issues with speed humps etc. However, with the M performance splitter I caught the underside of the splitter on a few occasions. With a standard car you won't have any issues but with a non standard front splitter there will be occasions you will need to be careful. Due to this I decided to switch kits.
I'm now using Eibach kit E10-57-005-02-22 which is officially listed for the same platform Mini JCW. This kit contains front spring F11-20-034-01-FA & the same rear spring F11-57-005-01-RA. I've found this kit has dropped the front by 2.5cm & still sitting on the same rear springs the 1.5cm rear. Still fitted with the same 10mm spacers. Looks wise this kit is very much more an oem stance, just slightly lower. The arch gaps are consistent front & rear & the car looks a little more level as opposed to the more nose down look the official kit gives. Handling wise, with the extra spring height I can already feel they are slightly softer & there's a hint of body roll back. These however just give that extra ground clearance at the front which will hopefully mean I won't cause any damage to my M performance front splitter.
I've attached a couple of pics, the two side profiles compare the two kits, the one in front of the garages is how it is now sitting on the Mini kit. There's also a side profile of the Mini spring kit alongside a standard car to give an idea of how it compares to standard.
Hope some find this helpful 👍
