| The back of the car has plenty of aero features, a dual plane wing, small carbon diffuser, fender flares, carbon deck lid and fiberglass bumper. A Mugen hardtop cleans up the aerodynamics. The bumper is vented and flare cut to reduce drag inducing trapped air. |
From the engine, power is directed to the wheels via a J’s Racing lightweight clutch and flywheel. J’s racing built the transmission using a close ratio syncromesh J’s Racing gearset. The transmission is hung on stiffer Mugen tranny mounts. The rear differential is a 1.5 way J’s Racing limited slip equipped with a 4.00:1 J’s Racing ring and pinion gear.

The J’s Racing carbon wing is a two plane type. These sorts of wings produce more downforce with less drag than your typical one piece wing.

The diffuser although small has the correct angle and vertical strakes for vortex generation. These make the diffuser more efficient.

The front end features a splitter and small canards. Although the canards provide a slight amount of downforce, their primary job is to create side vortexes that help reduce the amount of air curling under the sides of the the car. Since the F20C engine has way less power than your typical Unlimited RWD car, the aero elements on the S2000 are smaller so as not to produce so much drag to overwhelm the engine’s power.

The front and rear fender flares are cut away in back so as not to trap air and cause drag.

What really sets the car off are the radical body mods by J’s Racing. The bodywork is largely carbon with widebody fenders and flares, front and rear bumpers, spoilers, side skirts, rear wing, hood, doors, diffuser and decklid all the trick black stuff. A Mugen hardtop replaces the convertible top with the whole package being set of with Craftsquare mirrors. Custom body fabrication is handled by N1 Concepts and Design Craft Fabrication.

The front wide fender is cut away to avoid air entrapment. The side skirts have barge boards to help prevent air from curling under the car. They also take advantage of stagnation from the side generated vortexes to obtain some downforce.
|
 |
| The hood is generously vented. This prevents air from backing up inside the engine compartment reducing drag. It also improves cooling and increases the splitter’s effectiveness. |
The car is driven by our NASA racing buddy Andrie Hartanto with the crew consisting of owner Tommy Tang, Crew Chief Johnny Ngo with mechanics Andrew Eng and Jimmy Chillcott.
 |
| Sweet Craftsquare mirrors are my fave. Mirrors can contribute to as much as 15% of a car’s total drag so it is important to pay attention to their shape. |
Doing more with less is what this S2000 is all about and we are looking forward to seeing it on the track for the rest of the 2010 time attack season.
