Great look OP! I got Ferrari yellow calipers on my Jerez E90 and the color is stunning. You will find these brakes to be absolutely a night and day difference. As one of the posters stated STOPTECH is good and I had them on my RS4 before, but i felt the construction of the brembos, the pads, stopping power, usability around town to be a much better overall option.
I have had mine on the car for over 2 years now and several track events and pads are still in good shape.
Just make sure u bed them in properly and flush the brake fluid after events, as well as every 3-5k miles. Just my personal opinion on upkeep!
Be ready for your face to feel like its being ripped off under hard braking! Get some monoballs and toe links and u will have a smile on your face all day!
Cheers and happy New Year! Enjoy!
