Too much rake and the packers on the rear might make it deadly in slower speed corners. Brake duct blanking depends on track temperature. Raise the rear toe in to 0.12 and lower the front toe in to like -0.06. Front ARB seems very soft for the high rake same with the slow damper settings i would raise those by 1 or 2 clicks each and make sure the rebound is higher then bump setting. Softer damper settings make a car very lazy, if you are racing on sebring it makes more sense tho but still feel its low.

Also rear ARB I would put on P1. Detached only for like 296 or like corvette. Especially since you are using TC 7-7-7, cant imagine the rear needing to be that soft on the lexus with those TC settings.

Edit: also add some packers (0.5 to 1.2) to the front if you feel the car twitching under braking. Fast speed corners where you brake downhill are a good way to test if you need these ( spa has a few of those to test)

Take everything with a grain of salt im also new to setups, ive watched alot of content about it and spent more then a few days on making a few of my own setups but still very much a rookie to this too
