you could do as little as 2", just getting 2" coil spacers but you will have to do a good amount of trimming. 3.5-4.5" you should be fine. if you have the I6 tho, i wouldnt recommend 33's without regearing. it will be a dog! i drove around for a couple weeks with the I6 and stock 3.55 gears waiting for my 4.56s it sucked.
