However, if you don't have good enough racing skills, your BMW may spin out like crazy especially during rainy days...
(American muscle cars are even worse!!!)

However, actually building race cars could be very different than building road cars as those race cars run under a lot of perfect conditions such as the tires are warm, the brakes are hot, excellent drivers, the engines are warm, engines stay at very high rpm, the roads are very smooth, traction controls are off, etc.
I don't think we could run our cars under those perfect conditions all the time!!!
Toyota/Lexus cars may not be among the best race cars but they definitely are the best road cars...

This also matches my experiences on my previous cars 1995 Accord LX and 1998 Altima GXE long time ago...
Honda >>> firmer dampers but softer springs >>> firmer/noisier ride and more body roll but more stable on highways and faster turn-in
Nissan >>> softer dampers but stiffer springs >>> softer/quieter ride and less body roll but less stable on highways and slower turn-in

(The first time after 52K kms)I also drove my GSF this morning. As I expected the idle was a little high... (about 900rpm)
So I followed the SOP from Lexus factory manual. Guess what... Now the idle is 750rpm which is right on the specification!!!

I did the below process... (similar to SOP but not exactly)
1. Started the engine this morning.
2. Drove for 20 minutes including 10 minutes on highway
3. Stopped the car(but engine was running), turn off any accessory, put in the park and let the engine idle for about 3 minutes
4. The idle was still around 900rpm. So I drove for another 10 minutes.
5. Stopped the car(but engine was running), turn off any accessory, put in the park and let the engine idle for about 20 seconds
6. The idle was back to 750rpm. Yeah!!!
The below is the SOP from Lexus FSM...
