Hi,

My 200 20V is shaking under braking and unfortunately I think is because the ufo rotors are warped. So I need to explore options:

Easiest one would be to replace the ufo rotors, but so far I have not been able to find them, it looks like they are no longer available. If anybody knows where to find them please share the source link.

If I'm not able to find ufo rotors, I would prefer not to do any modifications, and find a bold opt option. With that in mind, and after reading multiple posts, it looks like one option would be to install the stoptech st40 for a B6 A4, as nuugen found out and posted here: https://www.motorgeek.com/viewtopic.php?f=17&t=49691 However, is quite expensive, and I've read that the rotor hats sometimes develop cracks.

I'm wondering if another option would be to use a similar kit to the old BIRA system 2 UFO system, using Boxter S calipers, Boxter S brake brakets for B6 A4 from apikol https://apikol.com/product/boxster-s-br ... -c5-2-7tt/ and then I'm not sure what rotors. Would the brackets work similarly to the stoptech brackets? Apparently no audi rotor fits, and the option would be to use Mercedes V12 rotors, but not sure what model/part numbers (if anyone know please let me know). I assume I would have to open the holes from 12mm to 14mm, but Mercedes center bore is 66.6 mm as opposed to 57.1mm for the Audi 200. Would that be the only modification required? Would that work? Mercedes rotors are likely to be way cheaper than stoptech rotor rings, so if this works it would be probably a cheaper option in the long run.

Finally, is there any other bold on brake kit that I may not be aware of?

thanks in advance for your help

A bunch of different options bolt on if your turn the hubs down. Just depends on your wheel size.

Thanks varia. Are the 6 piston Brembo calipers same as Porsche 17z or 18z?

Yoda, wheels are 18" and 17 Audi pie plates.
