I'll try to explain what I want to do ....

my 97. A6 has 288mm vented rotors which are sluggish and I would like to upgrade for some "better size" keeping the costs as low as possible

I've found out (thaks to AudiWorld) that simply replacing brackets with ones from TT would alow me to use 312mm rotors used on A8 etc. keeping my calipers and using same pads (type not old pads ;))

my question ... are there any other maching brackets?

if someone have some better solution, please advice me

thanks
