if you dont lower the car then you will need to get at least 18's on the 6 due to the fact that it will not look right with that much gap and a kit on it. no matter what you do the front end will be LOW, i know, i had my GC's all the way up and its still low, i would say probaly about 5in at the most off the ground. just be very very carfull about going anywhere you might hit anything, you can rub just dont ram in to it.
