Understeer after Eibach Pro install

Hi Guys

I installed Eibach Pro springs with Bilastein B4 (for M-Sport) dampers, with M-Sport spec bump stops. This is on an E91 325d SE, I have kept the SE anti roll bars due to having to drop the rear subframe to fit the upgraded rollbar on the back.

The handling is now much more planted, if not slightly on the crashy side (but I have gone from SE spec so am used to soft suspension).

One thing I don't like is on hard turn in, for example pulling into a side road quickly or going fast round a very tight roundabout it under steers.

My old E46 touring, had the milder sports suspension and never ever under steered.

This car does have a staggard set up, 225 18" front 255 18" rear. Is this a characteristic of the set up or are E90's set up to under steer rather than over steer for safety??

I don't like it, feels like driving a front wheel drive car.

Any ideas why this might be happening if it is not normal behavior???

Wondering if I should have jut fitted M-Sport springs, I have a set sat at home.

Thanks in advance for your helpfull advice

Andrew
