Carbon interior

[RedTele58]

Yup. What Sti-986 says. And absolutely not to pick on you at all, but there is waaaay too much going on in that interior.

You're using at least five (that I can see) different interior themes.
Carbon Fiber
Alcantara
Yellow trim
Silver (aluminum look) trim
Whatever you're doing with the diamond pattern on the seats

It all screams 17 year old kid with his moms credit card at the accessory row at AutoZone. If you're a 17 year old kid, I'll give you a pass. But otherwise it's way too much.

Since you asked, here's my thoughts...
Get rid of anything yellow in the interior.
The diamond stitch in the seat? Nah. It's just another distraction that doesn't fit in.
If you're gung-ho on the Alcantara, the diamond pattern is especially distracting. One or the other. Not both.
Too much carbon fiber that is too much a contrast with the rest of the "upgrades".

Trying to put a good looking interior together is tough. It's too easy to go way overboard. The ones I see that look best to my jaded eye are usually no more than a primary theme (like leather) and something that compliments it in lesser amounts, like maybe a bit of alcantara, or carbon fiber, or a touch of color - like yellow thread on black leather.
If you're going to try contrast with material, again two - the leather, alcantara, diamond patterns, floor mats are all too much mismatch.
Your eyes should flow through the interior, not jump from thing to thing.

I'm sure I'm too much of a Porsche traditionalist, but it looks like your trying too hard to mix custom mods that I'd see on an Asian market tuner car into the more traditional interior of a Porsche. I think with what you're trying to do, less is more.

But like we say around here - it's your car - you do you.
