More bodyroll and understeer on a E92 than a E90

Hi All,

I've been without my E92 for a few weeks now and had a E90 instead.

Both M-Sports and according to RealOem, both have same shocks e.t.c. However, my E92 has more bodyroll and understeer than the E90. The E90 feels more consistent with the E87 1 Series.

Is this normal with the E92?

Ah maybe that's why. The e90 had 18" wheels with rft and the e92 has 19" wheels with rubber band tyres

Also depends on age... we have a 2008 E91 in the family and it drives differently to my 2006 E90. BMW soften things up to make it more refined.

I thought the same but my 2005 1 series and the 2011 loan car e90 drive the same, yet my 2010 e92 feels different from both?!

Tire pressures can also make a large difference

I have been playing around with tyre pressures recently, in order to get a more comfortable ride with the Bridgestone rfts. I'll adjust them back to factory recommendations and see if it makes an improvement.

Thanks

When I owned my 07 320d E92 M sport, I also used the firms 320d E90 M Sport of the same year and found no difference in ride or handling.

Agree..

Also the E92 is longer, and it used to be heavier than the equivalent E90 (whether it is now i'm not sure)
