here is my suspension mod list
koni yellows all around
zsp springs from e92 mt(i believe mt e92 have the shortest springs)
dinan camber
m3 front control arms
sp lowering perches
cusco strut bar
megan racing toe
no LSD
245's upfront/255 rears to minimize stagger(pirelli rosso)
i have thought about installing front sway bar, but i have heard it can induce more understeer. UPgrading rear sway bar makes the car fish-tail happy unless LSD is already installed. is there no other way to get more grip upfront to kill this body roll & understeer?

Ran into your suspension thread searching for something else. Was curious to ask if you ever solved your problem?
You got absolutely awful advice at first then some others chimed in with much better advice. Still no one ever brought up proper suspension tuning advice such as logging tire temps, adjusting your roll couple distrbution, calculating suspension frequencies, etc, etc. so I was wondering how it all turned out. |
upon inspection I found that passenger side lower shock mount was missing 1 bolt and other was loose which made the shock move around, hence giving that body roll type feeling.
I have since installed new lower shock mounts and ride is super good. car feels very stable, absorbs all road bumps without unsettling the car.
I even attended a 3 day performance driving school, and car felt great. I could have benefited with higher spring rates and a LSD but a super smooth dd is my priority and LSD is lil too much money(for me) to justify.
