4x4parts.com is all nissan stuff. they have kits available for the r50's. the company that runs it is called automotive customizers, so when browsing through here whenever somebody says ac thats what they are talking about unless its air conditioning lol. most people with r50's get new suspension components and wheel spacers for the front and som slight trimming of the front underside and can fit and flex metric versions of 33' tires. another forum you could look at is npora. just google it.
