He made an assumption on the weight of his car and is presenting it as fact. He did not weigh it nor did he weigh the new parts on and the old part coming off his car.
Yes he has made a lot of changes to his car. Taking 200lbs off of a car is a lot harder than most believe.
I originally posted in this thread because thing positive he had to say about his new 100k car was about the tires. That's funny!
You're going off half-cocked, and you don't even know the full story. Actually, I didn't make any assumptions. I DID weigh the new parts as well as the old parts that came off, and posted about it probably two years ago. Hell, I've posted about the near 100 lbs rotating mass that I've removed so many times that I'm tired of typing it. And I'm sure people that have read it are tired of reading it!
I'll see what I can do as far getting my GT500 on some scales. Any tips on how to make that happen would be appreciated.
