I was in the dilemma as you before... My car was on b8+eibach, car handling was excellent but the undercarriage will hit every bump that i went thru and stiffness of the eibach spring is very uncomfortable for the passengers.
So decided to change the eibach spring to ori spring, well you have to give up something to gain something.. My car currently is more driveble especially in our pole hole infested country but at times when you need the handling it is not there...
Well it is a good question by 2wenty6.... How do we identity it is Mtec spring? FMHO the height of the Mtec spring is only slight lower than the ori spring... Any opinion from you guys?
