Hi, I changed my wheels and tyres last year (I put Avon now) and as the front tyres are a little smaller than the old ones (225 instead of 235) and the back are a little higher (295 instead of 305), the car seems to be higher on the back. I would like to lowered the back a little but I do not know if it is possible just to do this by turning the ajustables shocks or if I have to change the springs...Thank you for your help.
