I have to say, I hate chrome wheels, and I hate spinning dubs.
The point of alloy wheels is they're light, and very strong. Dubs make wheels very very heavy, plus they're just one more thing to go wrong. They are very gangster, that's true,- But I don't think I'll see Dre and Snoop to the D-O-Double G dipping through Compton, Longbeach, or Inglewood in a Saxo or Corsa on 20-inch chrome dubs. They just don't suit hot hatches, big yank cars or jeeps fair enough...
I think those Lensos would suit your car, OZ SuperTs or OZ Titans.
As for your car Scooby's *****, seen some Astras, same shape as yours with SuperT type wheels, but in dark gun metal colour. They looked so good because the astra was in yellow, so maybe go for the normal silver style ones...do a mock up in photoshop to see which it suits best though
