I have 20" rims (8.5x20 ET35) and I need help choosing lowering and what size of spacers I need.I donīt have airmatic.
Is about 35mm lowerin OK.
How about 10mm spacers front,and 30mm spacers rear?

I allready buyed 30mm lowering kit.Please help!what kind of spacers I need for those rims?

30mm is pretty big. Do you have pictures f the car, with any measurements as to how the wheel sits. Remember, the bigger the spacers, the more stress you place on wheel bearings.
