i like the bbs RC's on my mk4. Like Ar6rider said, SAVE. DONT buy reps, they will ride like shit, bend, handle poorly, and warp. My brother got the same wheels with brand new toyo proxes 4 tires for 800 bucks. Look around for used 5x100 wheels on VWVORTEX.com, go to the euroshops around your area, and be patient. BBS, Borbet, Miro, Rotiform, Rota, and audi wheels.
If you really wanna stay under 500$, look for some audi wheels, or volkswagen monte carlos or detroits. Those are the wheels that came on certain GTI/Jettas. You cant go wrong with a stock wheel.
Much lower now though haha
