its been 1 year since i have been to winton in the micra, and this is my 3rd time in winton with micra...

Session 1
this was the practice session... quite a bit of traffic and had to overtake few cars.... micra is bad at overtaking 
 so i am thanking everyone that letting me pass by slowing down on the straight... i got 1 free lap at the last lap and i was lucky to break my previous PB by more than 2 seconds... pretty surprised when shaun told me...
1:56.4900
1:52.3280
1:52.3950
1:52.3840
1:51.9380

Session 2 *TIMER NOT WORKING*
sayaka was in the car as passenger... it was a good lap and according to race chrono i was doing around 1:52s.... i only have few laps as i had to pull out due to my bonnet latch opening halfway after few ripple strip hopping...
8:15.2700 - LOL

Session 3 *Fix the timer position*
few traffics along the track... no clean lap... but overall still good fun... however the car starting to feel abit slippery... so i decided to check my tyre pressure afterwards and it was 40 psi... o_O hahahaha so i knock it back down to 38psi....
2:05.8740
1:53.9600
1:54.3100
1:52.6860
1:53.7210
2:00.9690

Session 4
this session i had 4 quite clean lap as i only have to overtake 1 car each lap and everyone was so nice to let me pass right away...
2:00.3360
1:54.7620
1:52.8440
1:52.6550
1:52.4980
1:52.1480

Session 5
with Jules as passenger in the car... this was one of the most busiest lap but extremely fun lap as i slide more than 10 times and did massive slide on turn 4 and lucky enough to held it all the way like a RWD lol... it was so much fun that me and jules spent most time giggling and yelling hahahaha... it was a shorter session also my slower one as i spent most time sideways than straight... so i decided to check the pressure and all the outer tyres (left) jump to 42psi and the inside tyres (right) was 40-41... moral value: sliding = tyre temp + pressure goes up
1:54.4430
1:54.1820
1:54.0490
1:59.9340
1:57.9490

Session 6
decide to do it alone this time... i put the pressure all the way down to 32psi... and it works like a treat.... i was thinking higher pressure works well for street tyres... i guess i was wrong... will stick with 32psi hot next time around. it was the combined session of A B C... it was the best session of the day for me... and i was taking turns with adam's AW11 to lead and follow... that one happened to allow me to do my fastest lap of the day while racing adam... 
Smile thank you mate... it was my best neck to neck experience of the day... so much fun!!!!
1:54.8890
1:52.7500
1:51.3590
1:53.7050 
1:50.0600
1:53.2720

by the end of the session, my brake was cooked... the brake pad is nearly gone, the brake fluid overflow and the brake feel spongy along the way home... will need replacing soon...

this is one of the best trackday i've ever been and i have missed all my adrenalin fixes for a year it felt so good to be back!!!

feedback from the new mods installed:
header - alot of top end pulling power and ahiru didn't ran out of breath anymore... keep pulling till the limiter...
catback - raspy and knocking the arms... hahaha bad! but works so i cbf changing it again...
the negative camber really makes the car turn at higher speed... i felt it so planted to the ground even when i feather or flick it around... the car become extremely easy to drive fast around the corner... just point and shoot 
Smile
the coilover - i am a noob in coilover settings, so i just set to the hardest... in the future i will raise it abit more because at the moment it bounce around at the corner exit, and that costing me time... i reckon once that fixed i can be in 1:50 more consistently...
the adrenalin 185/60/14 - lol this is just the right amount for the micra at this stage... my first trackday with the worn old tyres was enough for the soft stock suspension, but then the semis i borrowed from darrin for my 2nd trackday was bogging the car alot on the exit (too much grip?)

so i am 90% happy with the car atm... just need to fix the bouncing at the exit, better brake pads and brake fluid and abit more power hahaha
