Order of improvements??

Hi everyone,
I know this topic has been discussed to the point of exhaustion, but I was still curious. So I know the general order to improve the car without touching the engine is tires, then rims, and then I'll go for the suspension. But if I was doing one suspension modification at a time which should I start with. If you can a list in order . Please, and thank you ahead of time.

Better handling, it takes too much to up the engine, plus I was reading and it was said that the last thing to touch is the engine. So handling, and a better feel all together, thanks

I would start by getting rid of the RFTs and installing Koni FSD shocks. That should get you better ride quality, better handling and make the car much less likely to become unsettled on rough surfaces.

I would not go larger than 18" on the rims and IMO you do not want to make the suspension any stiffer as in my experience lack of sufficient compliance was a problem on the E9x, particularly with the sport suspension which was standard on the coupe.

Shocks/springs, matched - many options - camber plates are good
Limited Slip Differential - Wavetrac or Quaife
M3 Rear subframe bushings
M3 Suspension arms
M3 Sway bars - unless you've selected sufficiently high spring rates
M3 Tower brace strictly optional.

Mucho DIY doc available.

You're welcome in advance.

Many replace the front with a M3 bar, but don't do the rear w/o LSD or....deleterious effect to your handling over bumps especially in curves & turns.

You of course won't cure suspension ills with sways alone, and there are more important mods to make.
