It's hard to gice a specific set of criteria as to what is "rice."

I always refer to ricers as people who drive like idiots on the street. Nothing really to do with modifications. Also cars with nothing (and I mean nothing....not even different wheel covers) but a fart can I consider stupid...but rice is a ridiculously overused term. Other than that, it's not really about what's good and bad, but what you like. For example, I have alcantara shift and ebrake boots in my car with color matched stitching. I love them, but my fellow car nuts don't always see the point. It's a personalization thing.

Those kits look pretty good, by the way. I especially like the top picture.
