Our first check of the IS500 exposed a flaw. After 6 stops from 70 mph and 3 from 100, the brake pedal felt like we might stepped into mashed potatoes.
VIR is even more challenging on brakes, major us to surprise: At what level will the brakes fade? Heading into Oak Tree? On the back straight, the place the IS hits 135.8 mph? And then Lexus informed us of a modify: “We’ve mounted prototype entrance pads that will be marketed as an accessory.”
Brakes are crucial when there is a 472-hp 5.-liter V-8 that can contact up 142.2 mph on the front straight. Involved about the brakes, we eased into them and our anxieties at some point subsided. Though the brake-pedal truly feel won’t inspire a lot confidence, the brakes and pads survived three days of lapping with no incident.
A bigger dilemma turns out to be cornering grip. In Change 1, the Bridgestone Potenza S001L tires only deal with .87 g. Driving off the corner exit calls for tolerance too. Hit the gasoline much too early and the Bridgestones depart powering a smoke screen. A much more intense tire decision would assistance at VIR.
On a quickly lap we did manage to overheat the 8-speed automatic, causing it to burp fluid out of its vent. When that took place, the transmission refused to upshift, sending the V-8 bouncing off its 7300-rpm rev limiter. This thermal drama transpired in spite of an auxiliary vendor-put in transmission cooler. We get that the IS500 is just not developed to be a monitor car or truck, but its 3:04.9 lap trails the RCF Track Edition by only 2.3 seconds. We can believe of a couple of small tweaks that would surely near that gap.
