Yep.....not too many out there.^ Love these shots. I also love how there are only a handful of sports cars that actually sit lower than the NSX. So far I've counted Ford GT, early gen Viper, Lotus Elise, Diablo and Murcielago - all of which stand right under 45 inches tall.
Actually it's a custom diffuser, but less as aggressive as difflow.Great pics,the NSX looks awesome,love the difflow,mine looks almost similar like yours
