I think any amount of poke / wheels sticking out of the guards is considered illegal, that being sad it's pretty much a gamble game of getting a good cop or bad if your going to keep it that way. I've been running XXR 527's for 6months now and they poke like shit but you'd be surprised no cop attention yet *touch wood* despite having them drive behind me etc just amount of luck I guess but hey thats my 2cents.
