Default S4 vs A8 brake upgrade

Is the general consenus, that since upgrading the rear rotors on a MY00 Quatro is not a "plug&play" option to the S4's vented. Since you still have to buy new calipers that you should just bite the bullet and go all the way to the A8's.

Same for the fronts as well?

Default Re: S4 vs A8 brake upgrade

Unless I'm wrong, standard A8 rotors are 269mm by 20mm, vented. S8 rear rotors are 22mm. S4 rears are 245mm by 20mm, vented. S6 rear rotors are also 22mm thick.

It'd be obvious to use the largest rotor for heat dissipation, and since calipers will need to be swapped, you might as well get the best option.

Has anyone ever gotten the S8 or S6 rear calipers & rotors? Any reason why it wouldn't work?

Default not sure if anyone ever tried to fit the A8/S8 rears, but people have fitted the S4 rear onto the A4

Default Was it a direct fit, or were new S4 rear calipers needed

needed to work/fit with the wider vneted rotor vs stock solid?

you need S4 calipers, rotors and carriers for the rear brake swap to A4
