Hey guys, I've found some 997 4S front brakes(calipers+pads only) for a pretty good deal. I'm playing with the idea of retrofitting them on my STi, but not sure about the factory rotors' size(or the min/max they can fit). I tried to search but no luck?

Can anyone point me to the right direction or tell me the specs?
Anyways, here are some pics with a part number if that can determine the model year or lead to anything...

Thanks in advance!

 

these are brembo for porsche.... ask them....that's why it says made in italy...

 

They are 330mm rotors.

It may be more then just upgrading the calipers to make them work. You brake systme may not be able to handle the requirements of the pistons on these brakes. I would do some more checking before you spend too much time and money trying to do an upgrade that won't work as well as your OEM system.
