I am planning on doing a grill block to my crx.
Mine has the later ( vtec ) front end.

Aswell as installing a lower front lip, i am thinking of blocking one or two of the grills.
I think ill go for the larger bottom one first.
However , as it is the vtec model, i don't want it to be noticeable ie : to detract from the sporty looks .

A lot of people put coroplast ( or similar blocking material ) infront of the grill , right? To me this seems like the easier and most likely more efficient way to do it obvious.... However it may spoil the looks ( in my eyes )

So i was wondering if it would be worthwhile to block it from behind? So from the outside it looks like it has a functional grill .... but in reality it no longer does.

Im trying to work out whether the mouth of the opening will act more like a parachute ( higher pressure zone ).
Like imagine the lid of an aerosol being pushed ( open end ) forwards through the air..... Its going to be acting like a parachute, as the air inside cannot flow out the back.

Opinions ?
