I'm returning back to this thread to give a bit of feedback regarding the stopping power after the mods..
550 discs, FD stainless steel brake lines, FD high performance pads. I have paid approx 650 euros inc fitting to make all this happen. I feel the total result is good but expensive. Have not pushed her yet (will do it this weekend), but i think someone should make effords to make a complete brake kit, just like the FD's, but this is far expensive.
Personally, i'm waiting to sell the Saab, which has AP's 6 piston brakes, and put them on the Massa.Or wait for Loz to sell his APs.
In the meantime, if anyone sells his FD carbon pads, i'd be happy to try them as well.
