I will be lifting my 2004 WRX with FXT struts & 3/8" saggy but spacers. I will be fabing up some rear trailing arm mount spacers. I see 1" 1.5" and 2" sets sold on line. If i keep the stock mount, how much drop would center the wheel? I have seen mixed reviews of the 99 OB mount, where some say it does the job while others wanted more geometry correcton. I want to go with 215/65r16s Grabbers. I hear they are still a tight fit. Will they rub in the rear if I load up the car? We head to the mountains with 2 big dogs, 2 kids, the wife, and a cargo box on the roof filled with our stuff. I really like the look of the 215/65s but 215/60s are just under an inch smaller in diameter and may work better for us. Thanks!
