i have some pics of my car with hx alloys here http://www.aveoforum.com/forum/f85/h...94/index2.html
rabbit is right though. hub needs to be bored just a bit and i had to space out the fronts too to clear the caliper. i used a 15 mm spacer with some extended studs. part number for the stud is 641 - 1581 in case you wanna go the same route i did. i found them at NAPA though.
