**Opinions needed**
Hi guys, you all are the most informative and mature crowd I see online.
So I figured I should ask for all your professional opinions on what to do with my rear bumper for my C4S.
Here are some pictures of my car from the last photo shoot.


This is what I have in mind:
1. Rinspeed INDY rear bumper
2. Vorsteiner carbon fiber rear diffuser
3. Revozport GT3 style rear bumper
4. Keep it stock
Your opinion are much appreciated.
Thanks in advance!

I can't see the photos. But I'm all about modding cars. Done with class it gives a uniqueness to the car. Given that, Rinspeed all the way. They only do Porsches and Range Rovers and know what they are doing. Just make sure you keep the stock parts when you plan on selling it.
I have the GT3 style rear bumper on my C2S and love it. Subtle but much more aggressive than stock. Even without a wing. I think your car looks sweet as it is but either of these bumpers will make it that much more unique.

Thank you all for your honest opinions!
I got 7 responses with 5 or 6 different answers . It's getting more confused now
Your car looks great! but the Vorsteiner type 2 bumper is a little too much for my taste.
Rinspeed looks great but I'm not sure how they gonna look with my factory aerokit.
Thank you! I like how it looks now but the stock rear bumper looks a little plain sometimes
I never sell any of my stock parts. Thanks for the heads-up.
I agree, just that I'm not sure how they look with the factory aerokit.
I like the GT3 style rear bumper a lot.
Well said! I'm leaning towards this idea right now.

I think your car looks great and if it were mine I'd leave it alone.
However if you really want to make a change, from your list that you are considering I'd go with the Vorsteiner carbon fiber rear diffuser.

Thank you! I will keep that in mind.
I am on the fence now, I think I will go with either stock or just the diffuser.
I remember you, your car looks amazing in person, very unique! I love the color.

How about a European rear bumper? Will look just like stock, minus the rear bumperettes, which will clean up the rear end nicely for a subtle change.
I know this is a turbo rear, but the effect will be the same. Get in touch if you need some help sourcing one.

i dont think the vortiener pieces do the car anu justice so i'd scratch that idea.
personally, id either keep it stock, or add the gt3 rs rear bumper since you have a wide body or the gt3 side exhaust bumper
