well i am a new member here and i just purchased a 2007 scion tc and i am debating on whether i want to install strictly aftermarket parts, TRD, or a little of both. from experience, i am used to installing nothing but aftermarket parts, but i have been out of the scene for a while and i am looking for some suggestions. i just am not sure if spending money on TRD parts is really worth it because it doesn't seem like they are going to give me the preformance i am looking for. what do you guys think?
