Are there any 4 piston calipers (not necessarily brembos) that fit on the automatic TL that don't require new rotors or any other additional hardware?

 

No.

 

what about with replacing rotors? Are their any that fit with the stock mounting brackets

 

Nope, not that either; going from memory, you need the following from a 2004-2006 6MT car or any 2007-2008 Type-S:

• Brembo calipers
• Disk Rotors
• Front knuckles
• Splash guards
• Caliper mounting bolts
• Flange bolts

 

Yes there is my BBK where plug and play bolt on with no adapters the only thing I changed was the rotors to type s rotors

 

Hyundai Genesis brembos fit with Nissan Rogue 3rd row seating rotors.

Acura TL Brembos fit with shaving of the caliper ears.

 

what bbk did you use?

 

That's the TL Brembo. He most likely had the caliper ears shaved, as I mentioned in my previous comment.

 

what exactly are the caliper ears? And how much metal do you need to shave in order to get them to fit? Do you just need to shave it to get it to work out do you need to changed more stuff. I always thought that putting the tl brembos required changing a lot of stuff

 

Caliper ears are the 2 bolt holes that attach to the knuckle/spindle. They look like little ears hence caliper-ears.

How much to shave off I have no idea exactly. I could take a guess but I don't want to say as I don't know for certain.
