Damn...the IS 500 F SPORT Performance was only 0:00.1 slower than the 2018 LC 500!!!

Phenomenal numbers. Imagine if the IS 500 F SPORT Performance had "F" Brembo brakes, tires (Michelin Pilot Sport 4S) and suspension (F Sachs Dampers)...

 

Very cool!!! I guess it's a sort of a draw between the LC's 10 speed and the IS's weight.

 

I just find it interesting that it's quicker around the track than both the GS F and RC F. Those cars have better brakes, so you'd think they could brake a bit later into the turns. Maybe part of it is driver skill.

 

The GS F and RC F were also tested in different years so there's no doubt that different conditions had an effect. Lists like these are fun and provide bragging rights, but I don't put too much stake in them. Those who understand a little statistics will know the data isn't scientific. They're using an n (lap number) of 1-4 (I believe), different drivers, and different days among other things, and yet they're measuring to a tenth of a second.

The important thing is that our car made the event. Lol.

 

Isn't the rear diff in the GSF & RCF different than the IS500?

 

If equipped, yes. I would imagine the ones being tested had the TVD (torque vectoring diff). The base models have the same diff (torsen limited slip diff).

 

Yes agreed there is a whole list of skills and differences as mentioned..

Probably want to look more at the weight differences and only 467 hp for those model years tested..
And the driver behind the wheel.

Also as I mentioned many times the RC F Track Edition benefits from the Torsen LSD on a track when compared to the TVD..

I think this highlights that the IS500 really is a grand tourer. the Golf R and Civic Type R were both faster.

 

They used different pads from stock, but I don't know if having bigger brakes would have mattered for the test. I seriously doubt that the clamping force is that much different between the IS500 brakes and the full on F-brakes. The main purpose of a BBK is to prevent overheating, and the write up did not say that the brakes were overheating.

Too bad that Lexus saddled the car with subpar tires though.

 

I would accept this statement if you put all lexus V8s which have slower track time than this car in the same bucket without making any exercises to prove otherwise.

 

why make excuses. As tested it is faster than most F cars out there and this is how life works. Numbers matter. To male excuses you can find many for anything in life. I am 100% sure if this car get Michelin tires it will shed 2 more seconds like LC500 did but again lets not use that excuse😊

 

does all those improvements matter? Its already faster that F cars at discount price. Just put tires it will be even more faster.

 

I'm using the numbers in the chart.

 

great! I was just trying to avoid unfair treatment of this car by some. If this is a GT then those F cars are are too. If those F cars are sports car then this car is same way sports car that can put better lap numbers.
