Since you have a '98, you should check to see if you currently have vented or solid rotors on the front brakes. I believe 4/1998 is when they made the switch from solid to vented, the vented brakes are the same ones that were equipped on the 323/328 models. __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
