Currently my only performance mod is iPE F1 exhaust. I am changing the X pipe to another iPE X pipe which claimed to have more torque. I drive my M3 95% on stop and go heavy city traffic. Anyway I am heading to the track soon. I have my 18" TE37 SL with Hoosier R6 ready. I am still on stock suspension. I know usually people who run slicks they lower their rides. Will this be a problem?
