Based on my experience tracking my M5 for the last decade it was a no brained. I went with Eibach Stage 2 on my Everglades. With a eclectic selection of other suspension parts while were in there I couldn’t be happier. Far better than stock.
My Everglades has shipped so I'm starting my build plans. Once I get it I want be lurking like I have for nearly 2 years waiting to be an owner. I'll post and my build so I'm in as a guinea pig too.
