This essentially confirms what we all have already read before... in a straight line, the RCF is not much faster than the ISF, and a modded ISF is faster than a "modded" RCF. Granted, if and when a set of headers comes out for the RCF, chances are it will edge out a FBO ISF, but still, the two are close enough in a straight line to be a driver's race.
The Lexus engineers never claimed they were building a straight line monster though. I'd be really curious to see some lap time comparisons between the two vehicles. The RCF, despite the weight disadvantage, should be the faster car around a road course.
If you're like most people, and you aren't going to seriously track your car, the incentive to sell the ISF to get an RCF probably isn't quite there yet for most people. You're losing a little utility and not gaining much performance all for some new tech and a new body. It's still an amazing car, but maybe not amazing enough to get a lot of ISF owners to go make the change.
Still waiting on a new ISF based on the 3IS body style. If and when they figure that one out, I think that's the winner.

And....2018. I still think they'll do it. 2018.

Brakes don't stop the car. Tires stop the car. The brakes are just there to collect the heat from the tires working. Don't misunderstand, I'd love to have carbon brakes on my F, but there won't be any easily measured performance difference between iron brakes and carbon brakes on street cars except at the scales.
