porsche and ferrari do it but it's designed using a wind tunnel so the intake actually works.
what's wrong with spoilers on FWD cars? i have a stock one on my VW and it does help the lines of the car. of course i don't think it'll produce any downforce at a speed the car will attain.
hate 92 hondas with a 96 VTEC engine, but a stock ecm and harness. it's slower than stock.
especially when they pull the a/c compressor, power steering, and put a little electric fan in the intake ducting. or the cold air intake under the engine, perfectly positioned to suck up the puddle of water on the road. i really want to hear one of those hydrolock one day.
