What are you looking to get? I cant read Japanese, but I didnt see anything good that they had. Just some misc. parts.

 

There is an artical in honda tuning about a S2000 that has Sun Auto voltage booster and Sun Auto grounding kit who got 7 HP and all his lights are brighter (head lights, tail lights, ect). Sorry the US site is http://www.sunautomobile.com/ let me know what you think.

 

bump...

 

there's been a ton of posts that dispute the claim that grounding wires add any HP -

 

Also, there 7 hp info probably isnt reliable. I'm sure if you dynoed your car right now 5 times, there would be close to a 7 hp between your best and worst numbers.

 

Not if you do it right.
