u/LSR1001

Looking at getting new pads and rotors for my Evo but I'm a bit lost on the DBA t3 4000 and HD 4000. Is it just looks that are different? do the 42224 . 42224s have any difference as the pictures online show they are both slotted rotors? i know the 42225 / 42225s have different appearances. same with pads, I heard the intima SS are good on these cars but also so are the DBA Street Performance.
