Most people are doing these things for asthetic modifications. You really need to be driving at 100mph+ to start to experience the aerodynamic benefits and/or be a pro driver, so whether you do the front or the back spoiler, for most purposes is really personal preference, rather than for track times.it's all good. i'm here for discussion. care to share your thoughts on why you feel it's not necessary to run a front spoiler on yours? thanks!
I'd say what DocCayman has done with the rear spoiler has really lifted the appearance of his GTS, as I think the Techart rear spoiler is really nice.
Personally, I think the GTS front bumper and splitters looks busy enough as is so maybe its not necessary to do the front spoiler and maybe adding the techart front spoiler woiuld make it look a little more chunky.
I think the Techart front spoiler looks better on the S, although I'd like to see the GTS version in person as photos don't always do justice and can excentuate certain features (e.g., new M3/M4).
GT4 front bumper/spoiler IMO looks very clean and would go well with the rear Techart spoiler.
