New to the forum, bought my first car and 05 SRT-6 with 50k April 4, 2014 after coming back from USAF Tech School.

I'm changing my brakes over, rotors to drilled and slotted and pads to full ceramics. Rear wheels are all done, however, I am having trouble removing the front wheel... The hub cap has been removed and the bolts are taken out. There is a center cap inside the wheel that I believe it is stuck on, but it will not come off (I'm assuming there is a nut under there like the rear)
If anyone knows how to remove that cap to facilitate changing the rotors and pads can you let me know? Thanks!
