performance parts

I own a 1996 z34. It is very sharpe looking with it chrome rims and tinted windows. I have built a custum intake for it, I have intalled a venom performance module, i have custom exhaust and a tornado air. What are some ideas for future modifications that i could do? Let me know what some good parts are?

FIRST OFF GET RID OF THE TORNADO, ITS A PIECE OF SHIT. SECOND BORLA MAKES A CATBACK EXHAUST SYSTEM THAT YOU CAN BOLT ON YOURSELF WITH NO MODS TO THE CAR. THIRD THERE IS A NITROUS KIT AVAILIBLE NOW MADE BY NITROUS EXPRESS, THIS REALLY HELPS IN THE TOP END OF YOIU CARS SPEED. MSD ALSO MAKES A HIGH FLOW FUEL PUMP FOR ALL MODELS OF MONTE CARLOS. HOPE THAT HELPS
