They are great for improving handling. Give the car a level stance and don't strain the shocks to much more. One thing, I have they 2.0 tdi engine So it may just be because of the extra weight but the car does not like it when there are sharp dips followed by instant upward inclines at speed. It feels like the car almost bottoms out. I would imagine with the tiny petrol engine you wouldn't experience that.
I know mine is a cupra but it should give you a good idea

Is it my eyes or does it sit lower at the back???
On a pragmatic note, did you inform SEAT about the change, and were there any warranty implications? Some have suggested on here that lowering using non-SEAT approved aftermarket parts might void the entire drivetrain (although I can't see any manufacturer being short sighted enough to really believe that lowering would have any effect on the rest of the drivetrain).
