Drop from Eibachs
 

I bought some Eibachs from a friend (he had them on his Classic for about 4 months).
I checked the numbers on the springs and they match those on the site of Eibach, about 25 drop..etc...

But on his car, the lowering was so severe that the rear tyres were rubbing when cornering hard !
Between his rear wheels and the fender was no more then 5 mm space !
He also had that bouncing and bobbing feel when driving the car..
So I was wondering if there are different type's of EIbachs, considering that the most of the cars with Eibachs are on an acceptable drop with decent comfort...

What number do you have written on your springs?
