Where Do I Find The Street Races?

OK, so you want to know where the street races are? All I know is that while I was playing yesterday, I stumbled across a chevron that lead to a Pay N' Spray's front door!!! I entered it and a screen came up where I could choose three races; then it became stored in my PDA! My advice: check all of the Pay N' Sprays; one of them should give you the option to street race:)

you can find one near a Pay N' Spray's called willis

Don't all the Pay N' Sprays have street races anyway?

Theory: Why not try beating all the street races and see what you get; obviously it should be something cool.

Thanks to those of you who have answered so far. So it seems the Pay 'n' Spray's are linked to the street races. I'm busy playing on my 360 at the mo (Lost & Damned of course!) so can anyone tell me if you need to be on foot or in a car to start these street races. I have wondered if you go in a car or it will do is spray the damn thing and not start a street race. We really need a detailed map to show us where everythign is on the map don't we? this is the first GTA game in a long time where apart from the actual missions you have to find everything yourself. It has actually made me want to explore Liberty City more than in GTA IV where everything is handed to you on a plate.

Hey thanks Simon Moon for the map, I'll check it out when I get the chance. I went to the pay 'n' spray in Willis as someone mentioned earlier in a post but there wasn't a race to be found! Do you have to be in a certain car for it to work? I tried a Sabre GT and I even bought a Revolution X but all what happened is I paid $200 for a respray! Is the race supposed to be next to the pay 'n' spray or what? What am I doing wrong if anything? I've even searched the area of Willis but all I could find was a scratch card shop, nothing else!

Look at the map I linked and then at the pay and spray there at willis. Now look to the southwest from there, you see a $ sign just above a camera. That's where you have to go. The races start only if you are on foot and step into the small chevrons. The pay and sprays have nothing to do with races, there just is one race start next to a pay and spray, that's all.

Thanks so much Simon Moon I have at last found the race! Am going to close this question now and choose your answer with the map so other people can find it. I must say that map is incredible, must have taken you a long time to do, well done to you!
