Thank you very much for appreciating my car...
Most of the answers you seek have been discussed in this thread.
4age is an outstanding engine but in my opinion its little under powered
for this kinda car if infact you are going with MarkII.
Expect to custom make everything as nothing is a direct bolt on this car.(H)
Those rotors with holes are called cross drilled rotors and in my opinion
its a nice upgrade but you'll hardly notice a difference with that alone.
