i got some alloys last night, went to look at them their a bit rough but i liked them so thought it was worth refurbishing them. When i looked inside one of the wheels they are et45, however when i got home i looked again and it said et38...... it turns out 2 are 45 and 2 are 38. the wheels are 17x7 which way around can these be fitted? will the 38's even clear the arches? if so would they be best on the front or rear???? so in future i will look at the offset on every wheel!
