Developed and track tested on our S2000. We used 12K carbon fiber providing extreme rigidity and durability. These do not flex whatsoever compared to a 3K carbon competitors offer. These side splitters even out the look of your S2000 by dropping the sides down to the same level as most front splitters and rear diffusers. Note: Dry Carbon items come pre-prepped for paint. There is NO clear coat on them so it is recommended that they need to be cleared or painted. We use pre-impregnated carbon material (Pre-preg) that has the resin system already coating the fibers. It is then autoclave cured in house for maximum compaction of the fibers and minimal surface imperfections. So there is as much as a 70% difference in weight and 45% difference of strength between the our carbon and the competitor's.
