I was told to invest some steering rack limiters because I was worried about rubbing when I get 17x9 03 cobra style rims along with the 245x55x17 tires. I'm having my steering rack and pinion assembly replaced but I was curious of how many of these little bushing like things have to be installed? I dunno how exactly they work but I went ahead and purchased a 6 pack anyways so I have them when I go to do it.
