I put Eibach springs on my
cupra but unfortunately I'm not too happy with them. I know most people seem to love them but I like neither the new ride height nor the ride.
I took before and after measurements and the rear end dropped almost 40 mm but the front only about 10 mm. With the stock springs the rear was about 20 mm higher than front, so now the front is sligtly higher than the rear... Also the ride is IMHO rather choppy at the rear.
I guess there are some production variances with springs and perhaps this is just a set that is a little off?
I liked KW springs on my previous car (golf V) so I might try them out later.
