Westlake Sport RSII RE-VISION - A New Perspective on Street and Track Performance
I've been using Westlake tyres since 2018 across all my cars. Recently, I tested the new Sport RSII 235/40R18 on my Toyota 86 at Sepang Circuit during Automoment Track Day in April and Subaru Track Day in May.
Before hitting the track, I adjusted tyre pressure to 24psi (165kpa), anticipating the high afternoon heat would increase pressure during the session. On my first hot lap in April(night track), I clocked 2:48.###. In May, with upgraded brakes, I improved to 2:45.###. However, I noticed the rear tyres twitching a few times. Back in the pits, my gauge showed higher pressure than expected, likely due to an inaccurate station gauge. I reset it to 180kpa and went back out—no more twitching, and I hit a personal best of 2:41.###.
Now later in the day with cooler weather and lesser traffic, I adjusted pressures again—26psi front, 24psi rear—and went for another session. First lap was 2:41.### despite some traffic. On what I knew might be my final run, I pushed hard. Timer showed green sectors; at one point, I was -1.82 seconds faster. I navigated T9–T14 as cleanly as possible, braked hard into T15, and crossed the line at 2:40.000—my new PB!
The new Westlake Sport RSII: major improvement! The reinforced sidewalls suit track use well, and the compound holds up better under heat. I believe there’s still 2–3 seconds left in these tyres. While not the absolute best in performance, they're among the most affordable options for what they deliver.
Thanks for reading!
