i bought the 1 piece spolier, front splitters for the mtech bumper, and rear difuser for the mtech bumper
i got mine at an average of around 50 - 100 $ cheaper then normal as i got them on sale (i looked last night and they are back to full price again
) but i got them from
www.bavauto.com , look at the aerodynamics section and you will see the acs stuff...
i think carshine is the local distributer?
have a look in the new thread i posted
