Guys, I just came back from Mainland China and spent 2 great track days there.
This time, I hired a professional driver to give me some lesson and let him drove my car by himself so i can record his driving and hopefully learn from there (he did 1:54.8). I also had Kansai sway bar , KW v2 and Jamie's bar installed. I know I shouldn't do it all in once, but here in Hong Kong, we don't get to go to track often.
The sway bars was set at the softest setting, the KW at 9 click open at KW stock height, and tire pressure was 23.5 psi cold. I found out the ideal tire (A050R) pressure is a lot lower on the 4c compare with other cars, probably it is due to the light weight. I didn't change the setting during the event beside the tire pressure as the jack simply wont slot under the car...
As I previously posted here, I had a big snap over steer at T3 last time i was there, and this time I was still afraid of turning the car into high speed corner (you can tell by the video)
But luckily I was able to shave 2.6 sec from my previous best record thanks to the driving instruction and Jaime's rear arm.
The car would over steer very easily last time i was on track, especially at mid to corner exit. This time, I could put on the power earlier and I don't remember over steer once at corner exit. The KW was too floaty (not sure about the right word) at the suggested setting and since the sway bar was at its softest setting (109% harder than stock) I am not sure if I can tell the difference.
I also tried trail breaking, and it worked really well for me, the car would steer as I release the brake. The front brake pad DS 2500 chipped and was almost gone by the end of the event, but there is still a lot left at the rear. My friend pointed a laser gun at the front brake disc 2 mins after I went back to the pit, and the reading was 485c, so I think I can use a more high temperature break pad in the future.
One weird thing is that my car would steer to the right hard when I lift off gas from full throttle during the time I was on the track. Now it would steer to the left when I put on full throttle as the turbo kick in on my way back home. Does that mean I have a bent wheel?
Anyway, I had great fun and was really happy about the result.
