what nice said. so long as you get 17x7" rims you should be fine with a 60mm drop. i suspect you might have to take out your rear arch liners though. do you really wanna go that low? thats gonna make for a bit of a bone-shaker imho

If you have a 7.5Jx17 rim your offset will change, most probably decrease as the rim is wider. The offset of 38 applies to the std rims.
You have to do a bit of maths and work out the new offset given you have a wider rim.
