Nub on front calipers
 

Alright, there is a nub on the front calipers that is making my aftermarket wheels not fit. I am guessing that it was put there for a reason and so I'm not too keen on just grinding it off half/all the way to make my wheels fit. Is there any reason it is there though?

Do it the 88Integra way and grind it off and see if a hole appears. Stock calipers are easily enough found on ebay.
