BMW 1M, M3, M4 suspension, weight transfer

Not putting it into Physic bugs as I haven`t driven these cars on track and it probably is not bug but for those who owns those cars is the suspension really that bad ? 1M mostly and M3 to some extend too ...M4 is fine I guess ...

I assume default setups are within reasonable range of real factory setups ... and given than 1M has suspension from M3 (? .. I think) which (sadly only on road) felt quite good

Suspension is super soft, cant handle weight transfer, waveing and upsetting car ... I mean it drives like Skoda Superb when you put it to super soft Comfort Mode and go over 180kmh (that is not pleasant experience)

It is way more stable in Superb when you put its adaptive suspension to sport mode than in 1M and M3 in AC .. not mentioning vRS I would expect to be closer to M series of BMW ... there is basically zero weight transfer influencing steering in negative way at same speeds in those cars

I get that part of it could be AC FFB pronoucing weigt transfer perhaps too much (but I don`t have that issue in other cars I`ve tried).

Or is it just bad default setup .. ?

I tried to find any info about it on web but everybody seems to praise the handeling, ballance an very low body roll

 

adjust tire pressure. in m3 u should lower on semislicks by around 7 clicks

 

^^This!
It helps a lot!

 

I`ll give it a try .. I don`t have issue with grip, I guess tyre being part of suspension will make some change ... just ammount of body roll is absurd on 1M .. and how it affects FFB ...

 

If I can add another question, don't know about the 1M and M4 as haven't been in one irl but the E92 my friend has is complete with various suspension settings (not sure if that is one of the extras though - his has the competition pack so not sure about the stock E92).

So which suspension mode is baked in to the AC E92?

My mate said when he drove it in AC that the AC one felt too slow but didn't comment on the handling particularly. That was on v7 tyres tho iirc.

 

I recently drove the 1M on the StreetFight server and I was asking myself the same thing, mainly questioning the super soft suspension and huge pitch variation. Funny thing though, the way Chris Harris describe the thing in that video is pretty much how it feels to me in AC.



Snappy oversteer, inconsistent grip, entertaining but not really fast, etc... He doesn't talk about weight shift though, that'd be interesting to hear from 1M owners. Well, I'm pretty sure Aris did try one of those at one of their track days events?

 

sure .. grip, oversteer, etc are nice ... road cars are highlight of AC .. I`m not questioning physics engine .. just feels like typo in shock values or something

 

Same thing here

 

Don't know if it was in one of Stefano's streams or somewhere on the forum, but usually it's always the 'sportiest' mode in cars that you can adjust, so stiff suspension, fast gearbox setting, sharp throttle and steering response.



The suspension might be a bit soft with too much pitch/roll, but maybe this is just increased because there aren't so many cars around that are really soft. (try the stock Z4 or Audi Quattro, those are boats compared to the 1M)


Also looking at he Chris Harris video, it looks pretty much like I experience it in AC with ST tyres.
It's not such a refined car as other M cars, the rear suspension was based on the M3, but with a shorter wheelbase.
Harris says it's more agile, but also more of a handful and snappy. That's pretty much how it drives in AC. Your always on the knife's edge to balance the torque, sometimes it puts the power down, sometimes it just goes sideways.
Have a look at his drifting too. The M2 is a pretty smooth motion throughout the drift while the 1M has more correction within the slides.
In another video, I think either M4 or C63 (the new one) he talks about his drifting technique and that he tries to do as little corrections on the steering as possible and control it more with the throttle.

 

from what I was able to find 1M has competitions package from M3 .. not just rear ... all parts are interchangable ...

I dived into bimmers forums and I found some mentions about stock shocks being soft and car boaty .. so I guess all good and we live in world where Skoda makes better "sporty tuned" cars than BMW

I guess it is FFB making this issue worse generating oscilation as car starts to sway from side to side resulting to self induced spin ...

No problem .. plenty of cars to choose from tomorrow

 

I like the BMWs, the cars are heavy, front engine, so, considering this. Also, BMW likes to use Mcpherson on front suspension, sporsts cars often use double wishbone or multilink.

They are really good cars to drift because it is easy to counter steering and regain grip gradually.

 

You really need to get your DFGT dialed in better. Or get quicker hands.

 

I have no issue with driving it, catching it not the point.

Just hard to believe m series feels like limousine in comfort adaptive suspension mode (yes did that on track too ) so I'm checking if somebody has that car as I only had chance to drive m3 shortly on road in normal speeds and haven't notice anything like that. If it is correct it must be scary and dangerous just to drive those bimmers on road at higher speeds.
If it was cars I've driven I would put it in physics bug section, now I just wanted to have chit chat about it.

In regards of dialing my wheel ... I did second clean install on different drive, I'm using ffb clip app and ffb is enjoyable again ... Not sure where was problem.
Strangely enough using same settings I was using since ever. Everything at zero and gain around 75 now set by app, not manually...
I'm trying enhanced understeer for now, feels closer to real car but I would love to cut that effect to half .. than it would be perfect.. I guess not possible in any config file? But that is minor thing ..
Also autosettings works great in

Thanks to everyone who helped in that pC2 thread.. my wife is not happy though

 

Often modern sportier cars tend to be borderline "undriveable" (read: messy and not effective) without assists... it's like they just dont bother making cars actually good and just let the assists figure it out.

BMW diffs are terrible as well... M Sport mechanical diff is fine but the usual E-Diff stuff is just... no. Huge understeer off, then drift mode on.

Oh and most street car's suspension is bad on track, because street car. Only the most extreme examples are acceptable, and even then easily improved (Manthey Racing coilovers on the Cayman GT4 for example, which make the balance actually good).

 

OK William .. I know you spent your time on track in road cars (if I`m not mistaken you for somebody else) so I`ll take your word .. and I`ll assume AC factory setting don`t necessary include all systems 1M/M3 has to keep it steady under normal speeds .. nevermind I`m not gonna spoil my freshly regained love to AC by two cars and I`m gonna stick with Skoda making better (not more fun) sporty cars than BMW

 

Well, not me personally but other people who are pretty good behind the wheel and could drive some of these on track.

At the end of the day a street car is just really messy on track, its just that the modern stuff seems to rely too much on electronics.

 

Slightly off-topic but after I sold my real life fun machine and drove bunch of "normal" road cars, it was quite a shock. I was asking myself how anybody can drive these cars when initial steering input goes into suspension first and the car does not rotate at all? It felt just so wrong and terrible! Still I thought my little fun machine was quite soft when I really wanted to have some fun with it.

Tyres gives you so much grip that even the "sporty" suspensions might feel like a boat when pushing hard.

 

Could be .. as I said .. only driven M3 for short period on road and spend few hours as passanger so me comparing it to cars I`ve driven on track is bit unfair ... I guess after hearing how good it handles body roll and how stable it is I was cought by suprise by its inablility to handle body roll and how unstable it is ... Its fun to drive, no question there ...

I also just noticed that semislicks are default on M3 series in AC instead road tyres .. I`ll give it another go today with street tyres ... see if those can handle real life speeds
