    Spec-D - GallerySpec-D - About

    Spec-D headlights and Spec-D tail lights are a great start, but the company's assortment of exterior accessories makes it easy to continue your quest for individuality. A billet grille, spoiler and hood scoop will give your car a unique look, but if you’re a truckin’ man check out the bull bars and side steps. Take more along on your next trip by adding a roof rack, or improve your visibility when hauling a trailer with towing mirrors.

    Spec-D knows you don’t want to just appear like a go-faster, so they offer the performance pieces that can back up the look. Let your engine breathe with a high-flow air filter, cold air intake, headers, and performance exhaust system. They’ll unleash your engine’s hidden horses and provide the roar when you step on the loud pedal. And when you pop the hood, you can wow the crowd with engine dress-up bolts, covers, and braided steel and silicone hoses.

    • Spec-D® - Black Fiber Optic Tail Lights

    Because performance means more than going fast in a straight line, you can count on Spec-D for the springs and sway bars that will have your ride hugging the corners with a minimum of body roll. For the stance that gets the stares, check out the extensive selection of lowering springs, and to take the flex out of your chassis, Spec-D has strut bars, C-pillar bars, and traction bars that will get the power to the ground and put the precise in your steering.

    Your cabin is your cockpit, headquarters on the road. Don’t settle for what the factory delivered! With Spec-D you can personalize your space or make your ride track ready. Spec-D offers racing seats and belts that will help you stay in control no matter the G-forces, custom steering wheels and steering wheel quick releases, custom gauges to monitor all vital systems, and even carbon fiber pedal sets to complete the transformation.

    Cheaply made
    I like the looks of the headlights but the rubber on the outside of the headlight came off immediately as soon as I took it out of the box.. They could be made to fit a little better..overall I don't think I'll buy threw carid again..
