aero help

Ok so ive been looking into a new set up on my 92 coupe. I want to keep the stock front bumper and just get a front lip. The side skirts and rear bumper is my problems. I really like the look of silbeers kit, ive looked around for the "nismo" kit and cant find anything. I want a simple oem look but i want lower side skirts and either a nismo rear bumper or valances. If anyone has any suggestions for similar parts than please tell or if you know where i can get nismo body parts than that would be great if you post links. Sorry sure youve heard it a million times but i got tired of looking.:lamende:
