well i bought R1 concepts drilled & slotted premium e-coating rotors,with hawk performance brake pads, because my stock crappy rotors were wobbly. i know ther are many other combo's u can do, like f-body caliper upgrade with new rotors & pads. u just have 2 search the internet. good luck with your brake project.What type of brake and rotor combo (all four wheels) do you recommend from summit/jegs etc? I want to get rid of the wobbly crap stockers on my 2004 LS.
