Hi, Ive just got my hands on 17" Lenso stage1 alloys for my 1.2 12v Ibiza MK4 and I'm wanting to lower the car just using springs, was thinking about 40mm. I've heard it wont lower it much and lowering 40mm on the front the wheels will rub on the arches, is this true and can I have any advice about lowering the car please?
