I currently swap my F for a ctsv for quite some time now . The transmission on the F is the best feature of the car and what i miss the most of it. Reliability on the F is better than the american , even thought it is more complicated it never failed and worked always flawlessly. Ride too harsh though for everyday , but performed awesome @ the track (2008)

Ok....but what does you liking the CTSV more than the ISF have to do with the engine technology?

Something about one blowing up in the hands of the testerd also. Of course all the GM boys say that they didn't give it the proper break in period.

Breaking valve springs and dropping valves should never happen, but it has happened innumerable times over the years to just about every manufacturer because the accountants thought they could save money with cheaper springs.

Not all cars suck. All catastrophic failures suck especially when they start to be consistently problematic.

Yes, no doubt Aisin built a whole lot of water pumps for Lexus V-8s that failed prematurely. No one here lost an engine to it, and everyone who had a pump fail either got full warranty replacement or got assistance with the cost from Lexus.

But if you really want an Internet pissing match with no discernible outcome, you should go to the RC F forum and engage with ISF001. He will vehemently deny any issues with the RC F...
I already got into one on The Rav4 site about the mileage I get and everyone got far better oddly then they deleted the posting People running to the aid of the Rav4 claiming absurd fuel muleage numbers that just do not exist.

The C7 cooling system is inadequate. He was able to make the engine overheat in less than 6 laps at TWS. He said the C7 Z06 does not have a bigger cooling system than the standard model, so he decided not to waste any time with one, hence the Hellcat and the Viper.

This is him at TWS:

2004 Z06 at Texas World Speedway - YouTube

I feel sorry for his cars, but I know he is able to push them very hard.
Lance , The Supra that is smoking in the video ( tranny failure ) was me had to pull off the track right after Andy went by was not shifting and the trans fluid on the rear wheels made for a fun ride at over 100 ahhh the good old days .
