I am the "Brake Whore" of the VW world and i will tell you the following...
If you want to do Track Duty on rotors... you must have a 2 piece rotor.
- Everything else is a gimic, IMHO.
Drilling makes them worse (cracking prone, look at any Corvette)
Slotting is good but eats up pads faster
2-Piece cost about $500 but worth every penny to save your arse.
Cryo Rotors sounds nice but ehh, i wouldn't bother, it's cheaper to just buy a couple sets of OEM's.
You will not gain any braking power or longevity with any of the above solutions unless you get a 2 piece rotor. I have seen
those available here, but nowhere else yet.
Additionally if you want brake longevity consider the stillen brake cooling kit, $275 which will extend pad and rotor life.
FINALLY... Don't drive XP8 on the street they'll squeal like stuck pigs. Just swap out your pads for the track day. This also keeps you mindful of your pad level on both sets of pads.
Then again this is just my opinion... i could be wrong.
