The NSX was refined again based on high-downforced, lower-weighted and improvement of maintenance. For example, front wing was modified, and fins on both sides of the bumper were added. In addition, rear wing was large-sized with sub-wings to the end. Also its shape from rear fender to rear side was aerodynamics-designed. Another reason why Mobil 1 NSX had high-speed and its stability was its power plant. The engine mount was lowered 15mm by changing its layout. Then 3.5 V6 DOHC powerplant still obtains its power although the race regulation was more strict. The brakes were reinforced by large-sizing its rotor and changing caliper to Brembo-made from AP-made.
