I have a 2000 TA with a little over 20,000 on it and the pads already need to be repaced and I think that the rotors are done for as well. I would like to get a decent set of cross drilled/slotted rotors and I am wondering which combination would be the best for the money. I have heard that powerslot rotors and Hawk pads is decent but, are there any other suggestions out there.

I would also like to know if going with a steel brake lines increaces the braking power at all and if they are worth getting. Any advice would be helpful.
