When you say all the springs are equal, the rear pod springs should be set differently to offset the weight of the motor.
The best method is to place the car on a flat surface with the front of the chassis overhanging (preferably a table edge) and push up the front of the car from the centre of the chassis. Which ever front wheel lifts first adjust the rear m3 nuts to stiffen/soften the tension on the pod springs until both front wheels lift off the table simultaneously.
The car will handle differently due to the different cornering forces applied to the front tyres due to the unbalanced chassis loading. The rear pod springs are the ONLY adjustment on a mardave V12 apart from caster settings with washers...but thats another story

hope this helps
