Wow, I go to sleep for a couple of hours and already you've got 2 sets out.
This shot is just awesome. I love the colours of the cars, that sense of just a couple of friends hanging out in some hundreds of thousands pounds worth of supercars, and the sense of speed. Excellent composition!
I like this shot also. However, it's just a little too over-sharpened in my opinion. I have to struggle to find any "depth" to it because my eyes are just immediately drawn to the over-sharpened nature of the photo. Not saying the photo is bad, as a composition, and ignoring the grain and parts that are over-sharpened, it's a nice photo. But it just has that one draw back.
Your LFA in Tokyo is a nice shot too. Back I feel to enhance it, you should've left the stock wheels on it, because the chrome would've reflected in it, and make it look a lot more "realistic". However, it's a matter of taste, but I still really like it. 👍
