If I'm using a +42 mm offset and add a +20 mm over fender on the car, what new offset should I use? I'm also looking at 17s only. What width would be best for a more flushed look? Lowered on Buddy Clubs N+s about an inch. I also have a Buddy Club BBK.

It depends on the width of the wheels. Its width + offset for fitment. +42 means nothing without a width to correlate the fitment room. But lets say for example your running a 9" wheel. You would push the offset out 20mm, so +22.

You actually answered my question. I was thinking x8.5 or x9. Thank you!
