what spring do you have from eibach? Well I have eibach springs before I put on the 17"S the ride is very similar.Handling is sooo much better!! I placed the tire and rim besides my 15" whent they were still on the car.. Seemed to be about an inch taller at most. it's just more rim with my 235/40's, I strongly recommend springs.. They give th ecar a very aggressive look even with stock wheels.
