Thanks Leszek.

I just put new rotors on my car. The front ones were warped and a big brake kit wasn't going to work out quick enough. I wish I'd known then that the TT carriers worked and were only $100. Oh well.

The S4 rears are fine for me for now. When I need new rotors, I may look into your A8 carrier trick. Pretty cool.

Weight:

Unfortunately, unsprung weight is increased by 2lbs per side in the rear and by an unspecified amount in the front. I haven't weighted the front kit yet.

Braking improvement:

Distances are definitively shorter according to my G-Tech. I got 11ft of improvement over stock with the A8 kit front and rear and with 235/45R17 G-Force KDW tires. How much of it was due to tires and how much due to brakes I cannot say.
I have to wait until Spring to test the brakes on the track. When I only had the front upgrade there was no improvement in fade resistance. I'm hoping that the vented rear rotors will make a big difference.
