This question could just have as easily been posted in the Integra forum.

The reason a lot of "kids" run aftermarket wheels in the back and steelies in the front is due to the fact that cheap, large aftermarket wheels weigh a TON. Thus, they use relatively lightweight and smaller diameter steelies up front for the whole drag race thing. That way they can run the 1/4 in, say, 16 flat instead of taking 18 or 19 seconds to do so.

Note that all of the above information was taken from a fellow Integra forum member who copies that exact "setup" for the large amount of street racing his Integra sees.
