After testing on 9 different tracks, each track multiple times, I think I've made a tuning that I finally like. This is for the Lexus ISF Race Modified 07 with all tunings installed. In other words, I bought the IS F '07 from the dealership, did race modification, and then installed whatever (everything) that was still possible from the tuning shop, including soft racing tires. I won numerous races without breaking a sweat. My tuning made this car handle like my real life IS on the track. Unfortunately my real IS isn't modified (wife won't let me touch it). =(


Settings:

Downforce 25/30

Transmission top speed 236 mph

LSD 7/15/10


Suspension

Ride Height -16/-16

Spring 9.5/9.5

Dampers Ext 5/6

Dampers Comp 5/6

Anti-Roll 3/4

Camber 2.3/2.1

Toe Angle -0.10/0.04


Brakes 6/5


Please let me know what you guys think. I'm open to suggestions, as long as you actually try the tuning on your IS F RM first. =)

Tuner Comments:

What if Toyota had kept the Altezza and the naming scheme with it? What if they weren't interested in making appliances and rather in making driver's cars?


Well, this would be the result. Instead of the pure alphabet soup named IS F being the top of the line model, there would likely be two V8 versions... The AS500 which would be roughly the equivalent of the base IS F and the RS500 which we see here. Instead of 417hp as in the lowly AS500, there is a staggering 634hp; instead of masses of creature comforts and computers, there's a very spartan interior housing two front seats, a lightweight rear bench seat, and not much else. The result is a car much harder-edged than the IS-F and one that steps very firmly on the toes of the LFA.
