This works on non-M cars like 3.0si but doing it on the M would be pointless, the stock brakes on the M are better, they just don't look as nice. The 135i pistons on these Brembos do Crack under extreme heat but unless you track your car you'd be fine. |
It's def aesthetics why ppl like you and me spent what we spent on StopTech...performance wise the brakes on the car are just fine but damn...a BBK package just looks so much better.
My daily...a BMW 128i...i just finished the install of the 4 piston F30 calipers on 340mm X 30mm F30 rotors...the 128i brakes are just fine...but damn does it look so much better with those blue F30 brakes...best part is it's direct bolt on so if a 135i front set up is direct bolt on as well as the F30 setup I run...so on the 3.0si Z4...if the 135i setup works/is direct bolt on then....the F30 setup should/could work too...more options for 3.0i/Si owners...
