hey all. my brakes just started grinding..... so now it is time to do some brake shopping. im trying to keep it cost efficient but as always, love performance as well so i found this brake company called r1concepts that offer slotted crossdrilled chamfered brakes cheaper than most other companies. does anyone know how quality they are? ive done some research and paroused a bimmer and g35 forum and both seem to give them great reviews. does anyone have any knowledge and can speak for them? positive or negative? also not sure what pads to go with... thinking of going with the hawk hps 5.0 but if theres a comparable less expensive pad, im open to suggestions. thank you for any and all input!
