I have a 2014 328I with base suspension, I purchased used M sports suspension(struts, shocks, Springs, top hats, sway bars)… I attempted to put the Front strut Spring Combos in today and noticed the top mounts we're different. 4 smaller bolts(M sport) versus the base suspension with three larger top bolts.
Has anybody gone from the base suspension to M sports suspension and just replaced the base suspension top hats on to the M sport Spring and strut combo? Were there any problems?

Thanks
