A different rear end gear won't help the s2000 sell better. It doesn't sell well because most people don't want a small, 2 seater convertible. Also, the USDM RSX and Integra Type R don't have 4.77 final drives. The USDM RSX has a 4.389 final drive, and the USDM B18C has a 4.40 final drive. I don't know about your car, but isn't it pretty loud on the freeway at 80mph? Imagine being 500 or more rpm above where it's at now, and tell me it won't be noisy.
