Looking for suggestions
My beloved 335i was totaled, and new family circumstances (baby) required a bigger car. In my case, that was a 2013 535i Msport.
My main complaint is the "wallow-y" handling of the F10 (especially annoying since I'm coming from a sport suspension 3er with Koni FSD). Inevitable, I guess! Starting with a stock 535i Msport (with 704 / variable shocks), I'm looking for opinions on the right order to deal with this, since time and money are no longer unlimited and mods have to be strung out over time... I'm thinking of the following: 1) Springs (H&R or ACS) 2) Sway bars (H&R or M5/650) 3) Wider wheels/ Non-RFT tires (also needed when I increase power) I assume replacing the shocks is more difficult than it's worth, since I have the variable OEM shocks. Also, my highest priority is reducing the "wallow" when I drive over bumps (especially laterally on highways, i.e. lane changes). I will probably end up doing all 3 at some point, but what will have the most effect in getting the car to feel more planted, especially over bumps? Thanks!

Replacing the shocks with Koni, or another brand, is not as difficult as you might think. There are EDC error cancellors available from KW, for one thing. Also, I agree with the wallowy ride of the MSport F10 - I have the same model and year as you. Coming from my Msport E60 550 which handled much more like a sports car than the F10 stock for stock suspension, I do find you really feel the additional weight of the F10. That said, since labor to replace the springs is pretty much identical to replacing the shocks and springs with coilovers, that will be my choice. I already got bigger wheels and tires wth non-RFT tires. The ride is better comfort wise without the RFTs, the grip is also better. However, it seems to have accentuated the roll in turns and the settling when I accelerate hard. So an overall stiffer suspension is definitely in order.
I came to the F10 from my E60 the same way as you as well, my beloved 550 was totaled by a drunk driver in February. |

Thanks! I didn't think to look for options to disable EDC -- From searching, it looks like I can code it out, and do any suspension I want. Now the only dilemma is *when* to do that...

If you have variable shocks, than you don't have the 704 M sport suspension.

I have 704, and thought that meant I had variable shocks -- I assumed the mode switch on the dash adjusted the suspension also (not just the shiftpoints). I just looked at the car and don't see any connections to the shocks -- pleasant surprise! This is going to be fun...! OTOH, if this is how an MSport suspension is these days, it says a lot about BMW losing its touch as a driver's car...

I've recently added just the front M5 sway bar to my car and I'm surprised how much this simple mod has improved the problem you are describing and my car doesn't have the 704 suspension. I would suggest going with the sways first and likely you can install these yourself if you can have ramps and most typical handtools. You will need external torx sockets to remove the front bushings and a T30 bit to remove the end links. Also the sways are about $500, with installation done yourself. Springs will run $300-600 with another $300-600 to install plus another $100-200 for alignment. If you're wanting to save money, go sways first.
