Hello, I tried to ask this on Club Polo but no one answered so i'll try on here! As my car is getting somewhere now, just gone into my dads work, i need to sort this out. Ive got a set of 15" Mini wheels, the R81 7 hole, (Imola) They are ET45. and 5.5J if that is relevant? I want to lower the car not sure how much but i will need some lower profile tires. i don't know what i need, they are 175/*what profile is needed*/15 obviously! So i need a rough idea of what size i will need. if anyone could help at all, i would be be very grateful. As i don't have a clue! Also i need to know if i will need wheel spacers? Thanks, Sam
