Those are very nice words, Adeel...although they're quite untrue. I'm just a student of the art of automobilia, rather than a practitioner. I've been simply learning along the way, and Allah has been kind to have given me the means to indulge in this passion. The next time you're in DHA and you run across any ff these vehicles, honk, pull me over to the side, and demand a ride
It's the very least I can do for a fellow enthusiast.
About the rims, I don't think 20 inch rims on what is essentially, a small car, will look appropriate. They might work on barges like the Impalas, but for the Camaro, the stance needs to be more low-slung and tight and aggressive, rather than "ghetto" in my opinion. Thus, while your offer for help and sourcing is VERY much appreciated, I think I'll politely decline, nonetheless. But rest assured...I WILL be taking you up on the offer for similar endeavours, in future. 
Once again, thanks for the kind words, brother.
