I have been using slot and drilled rotors on my 92 LS-L for a year now with no problems so far and a lot better braking. I bought mine from NAPA with a lifetime warrenty the part numbers are PR86350L and PR86350R. They were a little spendy though. As far as the braided stainless steel brake lines go they are suppose to have less expansion and no blockage in the lines which equals quicker brake response. You can buy them off
www.motorsportwarehouse.com. I installed a set on my car and I noticed a difference. I don't know what brake pads you are planning on going with ,but I recommend Akebono Pro-ACT ceramics they have a nice bite to them, last a long time(depending on how you drive I guess) and very low dusting. The part number for the front set is ACT333. I don't have part number for the rear set. Hope this helped some.
