at 10:54 PM

UPDATE:
Lap Record for: Silas B. Andrianto - [MERAH] AKA Flameboy
350Z track -
wheels + tyres: Front - 225/45/17 Dunlop Formula R, Back - 235/45/17 RE55s, BBS 17x8 +30
performance mods: APS catback, Megan race pipe, 37kg weight reduction
brake: RBF600, Project Mu HC+
other: DIY oil cooler

i also put 1mm toe out at the front and 4mm overall toe in at the back... just testing...

at the beginning of the day, the car feel really shit and it understeer everywhere... then i figure running 38 front and back (cold) wouldnt work coz i think the RE55 at the back has more grip than the dunlop at the front...

so i keep reducing the front pressure until 30psi warm, and i was happy with that... its starting to grip like i want it on the 4th session...

the 5th session i was out trying to drift i think... lol... but it was more like a bush bashing... and i heard something pop! then i decided to stop... cant do it... better luck next time...

then on the last session... the individual session, i'm getting really worried, i was following johnny (he was driving scott's EVO) and i can hear this same wobble sound like last time... pulsing annoying hitting wobbling sound... last time was only at the back... and now is at the back and front... i ignore it... when i came back to the pit after 3 laps, that sound turned out to be the loose rear left wheels and front right wheels!!! both of them only have 1 nuts left holding it, the other 4 nearly fall off... Shocked

so i was very lucky... i torque the wheels nut on 80Nm... probably its not enough... i will do 85 or 90 next time...

but yeah, now with spring, cooler weather and no improvement in the time.... Razz

feel stupid... but ah well, better luck next time...
