hey i have a 2000 audi a6 2.7T and i was thinking of gettin 19" hartmann RS4 332 replicas but i dont know how to determine if they will fit my a6..... any advice would be great

Just make sure they're 5x112 and the offset isn't something silly and you should be fine.

Stick with a 35MM offset!

OOOO

Dido - make sure they're 5x112 35-40mm off set. Stock offset is 43mm for the 17' BBS wheels.
The wheels I have are 19x9 5x112 40mm offset - Perfect fit but will possibly add wheel spacers down the road.
