e90 325i msport rear horizontal shake(lift)

[kevincek]

Hi. I have gone concerned as to why my car almost feels like its losing rear traction/slipping when going over imperfections over the highway while cornering ( or even slightly turning the wheel)

Is this normal? As in, is this how msport suspension is suppose to be like? Im no race car driver so ive limited experience on matters such as kicking out the rear and executing a drift.
Happens whether or not throttle is applied, and was wondering if anyone else felt the same thing.

It concerns me safety wise, but also me having to slow down to at least (100kmh or so) every corner with bumps. And being beaten by a last gen vios.
Jokes aside,
If say iits not something I should be experiencing, will the problem be in the suspension/absorber itself or bad tyres?
Im using Michelin ps2 runflats at back. 18inch. Usual msport spec with msport suspension.

Ps. The dsc didnt light up.

Whats the tyre pressure for your rear tyres bro?

 

[kevincek]

34 front and 40 back. However my front tyres are non run flats. Only back.

Kevin, 40 sounds kinda high for the rear. I'm on the same setup as yours (M-Sports shocks, 18" wheels) and the tyre pressures are 33 front 35 rear. Perhaps try lowering the pressure and whether it helps?

the tyre pressure at the back to high bro....
