Tasteful exterior mods are never frowned upon here. Canards that don't even effect performance until triple digits or so, are probably pretty useless on an MR2. The only time they would even make sense is after all or most GOFASTBITS have been added and the car may then actually make use of such an item.
Wings I never really have too much of an issue with given they're not on a FWD car, and are at least functional. Though again, speed is what counts, if your car can barely get up to a functional MPH to take advantage of said item, why waste time doing it. Lots of ricers are surprised to learn that CF hoods, and canards, and functional body kits were invented to serve a purpose and not to look cool.
