Don't know if any of you ever get the Option 2 magazine there stateside, but there is a tuning shop profiled in one of the last couple issues called Yashio Factory. These guys have or can get just about anything you want for your S chassis car. They also are a dealer in HKS and NISMO. They even have their own line of products. They are track tested, and top knotch. There current team car is a bad a!! S-15. I might try to get some pics. But if you wanna check the website, unfortunatley in Japanese, here is the url.

By the way, I live about 2KM or 1.25M from there. Maybe the Mods and Admns would be intersted in a JDM sponsor. Let me know guys.
