Suspension Questions

[Dodge_Gowans]

Hi all,

Currently loving my car but deliberating how to give it a better look and improved handling. Practical and readily available solutions are preferred so I was thinking about installing H&R springs and sways and then getting the alignment setup with custom parameters.

I have a 2015 UK spec 640d GC and was wondering if anyone could help answer the following ;

1. Can we get anything lower than H&R springs allowing you to retain VDC?

2. Has anyone dialled in M5/M6 Geometry (or 550i/650i etc) into their non-M car?

3. Does anyone know if H&R sway bars from a F10 would fit my car?

Cheers in advance if anyone can help.
If not, looks like I might be the "Guinea Pig".
