[s-cars] Custom rotor hat for use with RS2 Brackets (993tt caliper/GT-3 322x32 rotor) & stock wheels

[Peter Schulz]

Steve:

Saves weight, but at what cost?
Unless you track your vehicle, regularly inspect/replace the 
rotor/hat , and/or live in a pristine environment (minimal salt, 
rust, potholes , are the benefits of switching from the durable cast 
iron boat anchor of a rotor to a multipiece rotor with an aluminum 
hat worth the potential issues?

some food for thought here:

Just want folks to understand that there are Pros AND cons for going 
with multi piece rotors and aluminum hats over cast iron
