Which Suspension Mods

[aswy6]

Hi everyone!

What:
As title says im looking to do some mods to my F80 M3 with the purpose to improve handling, overall feeling and responsiveness, basically want to make the car more fun and more connected.

Why:
Reduce amount of body roll and that floaty feeling, Cut down on lap times (yes im aware of driver mod), increase the overall feel of being connected with the car and make it handle better without sacrificing too much comfort as its still being a daily driver. Im okay to sacrifice some comfort though.

Here is what im thinking:

Option 1)
A local shop recommended for me to start with thicker sway bars (make front stiffer and leave rear as it is or 10% stiffer) so i was thinking about getting either H&R, aFe or Hotchkis. In addition to them also was planning to swap out differential bushings with some stiffer Powerflex (black)

Option 2)
MCS One way Non Remote coilovers. Does anyone daily drives their cars on these?

Option 3)
One of my friends with R33 GTR suggested for me to get these guys in link below as it made a huge difference on his car. Has anyone had any experience with this company and does it look like a worthy upgrade to you?

Which of the options above should i do first to get the most noticeable change? I was thinking to start out with 1, then move to 2 and finally to 3.

Thanks everyone!

Did you ever get the chassis braces from UltraRacing? Looking for feedback if they made any improvement.

Start with a set of quality adjustable coilovers. I would not mess with stabiliser bars. The springrates on a coilover kit will reduce body roll a lot. I run Öhlins and solid adjustable caster bushings.

Also check out the MP HAS main thread if you're on a tighter budget versus getting a coiliver kit. Much less body roll and ride comfort is not sacrificed.

Option 2 without hesitation.

Try 200TW tires first
