asikson, at first, I am not your friend.
Furthermore you told us:
In my opinion chianging part turns TT -> TTS because i changed everyting... Only in Brief you can see TT / 147KW
Obviously you didn't change everything! Now you tell you us that you still got the stock brakes mounted. So everyone who knows a bit about the TT can tell, it's not a TTS. It still doesn't turn your car into a TTS.
Also you are telling us that you have a company in Hamburg, but you complain about German prices.
My advice, don't bullshit around. If you can't afford to buy a real TTS, don't tell people on street it's a TTS. But I guess you don't have the courage to do so and keep lying.
I quit this discussion.
