Entire suspension is different, geometry and everything. Engine obviously is 10 steps above and it looks a hell of a lot better.

However if your eally look at all the extra supports, including the sway bars, undercarriage and strut tower big thick aluminum braces, the rigidity and handling is something you cant create with simply an aftermarket set of coil overs unless you are also changing out the knuckles, camber plates, toe links, adding several support beams under neath and adding a new strut brace in the engine bay.

Since you mention that big fat aluminium strut brace twice in your post, I'll just say that it costs a mere $250 and can be retrofitted in any E9X model, just as 90% of the chassis parts.

And if you track the M3 somewhat seriously, you'll change out the stock camber plates, toe links, brakes etc just the same as you upgrade them on an 335i

You're really blinded by the big ///M - Marketing.
