F82 M4: which lowering springs with 295/30/20 PS4S?

thecarsavant · 02-12-2023, 09:13 AM

I love my 666M wheels but hate 2 things: the harsh ride quality on MPSS (rears are run-flats from previous owner) and front fender gap. I want to swap my MPSS to MP4S all around (265/30/20 F and 295/30/20 R) while avoiding rubbing. The car is daily driven and I have no plans to track it. EMD springs seems to be the least aggressive in terms of ride quality. Any insight would be appreciated!

I'm in the same boat as you. I've heard good things about macht schnell springs as well

From some research done they provide the perfect drop with something comparable to oem ride quality. I've narrowed down my options to M performance has kit, kw has kit or macht schnell springs.

The bad ride quality is mostly in the dampers. I suggest you get rid of the EDC suspension and buy a set of proper coilovers. For comfort i recommend KW V3 or DDC's.

I get some Eibach Pro Springs fitted on Wednesday with 12mm Bimecc spacers all round. I will report back on any changes to ride quality.
