No Spoiler, done right.

Some spoilers look alright though.

 

hey thats my car ...wootwoot

 

So far im liking the sexy rear end s of the rx7s with no spoilers, dont get me wrong some of those spoilers look awesome, but sometimes nothing at all is better

 

Wangan is one of the big skyway (upper level highways) in Japan; infamous for high speed night runs. Pretty much any big ductail type spoiler
is considered wangan style (ie. high speed/low drag/good down force).
Anyway, I vote for spoilerless.

 

If it's a mostly stock body car, the stock spoiler works best for me. If it's a psychotic track car like Carl Byck's, then a big ol' APR GT wing works very well (looks and function-wise).
