I have had the 2015 f45 225i xdrive Luxury for 7 months now and even the wife comments on the soft and bouncy ride.
Replacing the run flats with proper tyres (Hankook Kinergy all season - front 36.rear34psi) improved the handling and harshness of the ride but the oem suspensions just seems very soft. It has no option settings on the car and it has a genuine 21k miles over 6 years so shocks should not be worn.
I have had the suspension given a general check over after a wheel alignment and all OK, no leaks, nothing broken, all looks tight, no obvious fault.
On my old Subaru Forester a thicker anti-roll bar, subframe lock bolts and KYB shocks worked wonders for the ride. Before I look to replace the shocks, which really shouldn't be necessary at 21k miles, is there anything else that I can look at first ?
I was wondering if the Active Tourer M-Sport has stiffer/uprated anti roll bars and if so ?? are they interchangeable with the Luxury as this would be an obvious solution.
Any thoughts appreciated.
Cheers
Brian.
