OH NO! More stickers !

The day started out wet, grey and gloomy, but when we got to the track after lunch, the track was bone-dry, it was as cool as we can expect for a tropical afternoon, and it was all good to go for the track!

In a bid to avoid stressing the car too much I planned only 5 laps each time I went out in addition to one warm up lap and one cooldown lap. I found the car suffered from a lot of corner entry understeer, maybe I was just entering corners way too fast. But the brakes held up and felt good for the duration of each run.

I also paced a Suzuki Swift Sport down the straight and found that the Yaris doesn't give up very much in terms of straightline speed. As my 5 laps were up, I didn't stay with him long enough to see if its cornering was better than mine, but I would feel that would be the case.

I got a little bit faster max speed than Marc (I recorded a 154kph down the back straight). However I suffered from pretty bad understeer which resulted in quite a lot of front tire scrub. Didn't really cross my mind to reduce tire pressures till toward the end of the session, when I really didn't want to go out anymore. This time I started out at 240kpa front and 230kpa rear, I think the car handled better last time at 210kpa front and 200kpa rear, much more grip.

Also had a run with a Proton Gen 2 Coupe which was surprisingly quick. I could overtake him (and he graciously gave way) but I found it hard to shake him and pushed too hard trying to lose him. He may have just wanted to follow me instead of being followed by me! Haha..

According to one of the more experienced trackies I was with, I clocked a similar lap time to Marc, he is very smooth and consistent while I was all over the place. He also gave some useful tips when he took a ride in my car. In addition I was making mistakes all over the place. So technically I had the marginally faster car (manual vs. auto), but he was the better driver.

I clocked near 20 laps. I went into the track with 3/4 of a tank, and filled up on the way home (I did 12.5km/litre which is not bad considering I was on high revs all the time I was on track). That, and quite a lot of Michelin rubber I'd left on the track, plus a bit of coolant lost. I didn't feel that my car was flexing too much, although I felt that the car hops a little through high-G corners when the suspension starts bottoming out.

Next time, I shall run lower pressures. The tire started losing grip by the 3rd lap onward. And I'll have to learn to manage the tires rather than just caning them to bits.

nice writeup, I badly wanna go on a track now

As for caning the tires... isn't that the Singaporean specialty?
