I'm guessing you really liked how it looks now, and the way it looks played a big part in your decision to buy it?
If so, then you really should just have it how you want and not be bothered by what others think.
I honestly respect anyones opinion on their choices of car mods etc .. and it's a 911 at the end of the day, they're all great!
BUT :lol: since you're asking
If i was to make a Carrera more like a GT3, the last thing i'd do is put the badges/aero etc on, i'd be more interested in making it feel more like a GT3 by upgrading suspension, cutting weight where i could, better brakes etc. I don't understand why people just want to make people think their car is a GT3, but not actually improve the handling and feel of the car, to me, that's why you have a GT3, for the fun they are to drive, the looks are mostly just a bonus from the purposeful upgrades they have (big brakes, aero for more downforce etc).
I'd love to put carbon buckets in mine, remove the rear seats, improve the suspension, put a lightened flywheel in it and just keep the little 911 badge on the rear. I'd like to make it more of a kinda 964 RS inspired 997, stripped back Carrera, raw and just enhance how it is already.
How ever you get your enjoyment out of the car, go with that, at the end of the day
