New Aero For Maximum Downforce - Project S2000

The front splitter is a direct fit for an OE S2000; some trimming, however, was required to fit with our custom intercooler/rad support.

We’ve been waiting in great suspense for this array of JDM awesomeness to arrive. The day when two giant J’s Racing boxes finally arrived at the door, I knew it would be a good one. Naturally, I couldn’t resist and tore into the packaging and unraveled every piece all 26 of them! From the photo (top), you can see it’s a bit of a jigsaw puzzle, but it all comes together into one awe-inspiring aero package.

What makes this kit so impressive is the attention to detail in the areas that can’t be seen. The front fenders feature a three-piece inner fender that fully surrounds the wheel opening and channels all high-pressure air smoothly out the multiple exits and into the free stream air. The rear bumper features a built-in diffuser, with aerofoils within the diffuser itself, while the front splitter features diffused exits into the wheel housings. Things that can be seen include a substantially wider stance, +60mm in the front and +75mm in the rear, compared to stock. The front nose has been lengthened substantially to improve front downforce, and optional brake ducting features two inlets per side. This allows for excellent flexibility to feed fresh air to cool the intake and front brakes. The side skirts are designed to sit flush with the OEM jacking points, making it possible to still get the car on a lift for service; this also makes for a perfect mating surface for the complete flat bottom we’ll be installing soon.

J’s Racing went all out on the GT kit, developing complete inner fenders and intricate ducting to help achieve maximum downforce.

The aero pieces are made primarily of glass fiber reinforced plastic, more commonly known as GFRP. We opted for the carbon-fiber version, which includes the front splitter, rear diffuser elements, side venting and optional brake ducts in CFRP, while the remainder of the kit is constructed of GFRP. Fitment is top-notch and very impressive for such an elaborate package. J’s Racing has spent countless hours designing and producing the tooling/molds to get this to fit just right.

Our custom intercooler/rad support required some modification of the front splitter to fit correctly; however, it worked out to plan and offers smooth flow to the intercooler/radiator combination. As shown in a previous Project S2000 tech story where we fitted the Spoon rear overfenders, you’ll definitely have to cut the rear quarter panels to take advantage of the extra rear room afforded by the rear overfenders. We took this one step further and cut an additional 1.5 inches up (total of 3.5 inches) to make the OEM outer quarter panel sit flush with the top of the inner wheelwell. We then fully welded the panels back together. The side skirts and rear overfenders are designed to rivet on to the body work and all come predrilled for the ideal mounting locations, as recommended by J’s. The attachment holes for the overfender and side skirt are hidden with the door closed, minimizing drag and giving a clean outward appearance.
