If you're lowering your car's height by an inch or more with a suspension kit, there is a possibility that your tires could rub against the fenders or other parts of the car's body.
This can happen if the new suspension setup changes the car's ride height and alignment enough to put the tires in contact with parts of the car that they weren't touching before. It can also happen if you're running tires that are too wide or have too much sidewall bulge for the new ride height.
To get a more accurate answer, you could try consulting the manufacturer of the suspension kit or a professional mechanic who has experience with your car's make and model. They may be able to give you specific recommendations for tire and wheel size and offset that will work with the new suspension setup without causing rubbing or other clearance issues.
