Do you like the M2 arms? I have them on my M140i but I find the car bumpsteering. I want to go back to original arms with Millway and Millway camber plates. I have an LSD (OS Giken is fantastic) :)

Yes man, it changed the car. Previously I was not enjoying driving the car even close to the limit, because I felt it eats outer edge of the tires. I don’t recall having any bumpsteering. Do you have only LCA, or whole set? I actually have lower LCA from M2 and black powerflex insert in stock upper arm that has adjustable caster. So caster is back to stock, but camber went to 2,2 deg. I bought it from some guy already preinstalled, here locally. Mine issue is slightly more NVH on harsh bumps. Basically whole cockpit rattles on very, very harsh bumps. Which was not case with stock soft bushing.

@@Svrcko944 yes you at the outer tyres indeed. I have both arms. I find it bumpsteering. The geometry changes too much of how BMW engineered the standard set up. M3 arms were a nice upgrade on the E9* platform. Will go back to my old BMW arms with Millway. If you go for an LSD 100% get a plated diff, M performance or Drexler or OS GIKEN.

⁠​⁠@@coenwagwill sure get the diff sometimes soon, thanks for recommendation. 👍 I think for me its caster adjustment and thats why I don’t have bumpsteer.

[@josefinkjellsson7051]

Still open diff? No LSD of any sort?

[@Svrcko944]

Still a stock diff, no LSD 🥲

[@josefinkjellsson7051]

Even more impressive, they are a handful without. Do you limit the Nm by gear trough xHP?

[@Svrcko944]

@@josefinkjellsson7051 Thanks! 😄 It's not as bad as you would think, at least not with the Cup 2's. Even though LSD is very welcome (I cannot wait to get one). I rely on throttle linearity in DSC off mode in oppose to the Sport+ where all the throttle is in the first 20% of pedal depression.

[@josefinkjellsson7051]

@@Svrcko944 so having good grippy tyres compensates that much for lack of lsd, interested 😊 I knew it didn’t but not to that extent 👍🏻 Sport plus is pure shit, sport and DSC off is the way to go yeah

@@josefinkjellsson7051 While we at it, there is a difference with grippy tires. Of course they let loose later (and they do let loose still), but also in corners where you would usually oversteer (e.g. exit of a hard right corner) and rear left would let lose first. With grippy tire actually rear right let loose first, which does keep you straight, but you have "one tire fire" for a brief moment.
