Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
Try putting some kind of bodykit on your car and see how many problems you have after that
Don't stick ultra lows in the back of it, then try to make it over a speed bump with someone in the back (even worse with a full tank of fuel)
It doesn't work, you will scrape everything, tell everyone to get out so you can make it over the speedbump, them tell them to get back in. Would look funny too.
Go superlows all round, and mabye get some lower profile tires.
