Rear Bumper Fitting
i bought the car with tow bar and the rear bumper holder has been modified and welded to the tow bar. so i purchase 2 rear bumper holder from indo wrecker ($10 for pair).
but the bumper bracket that i have is shorter than the bumper holder, so the cutting begins (thank you dan for the help!)
cut about 1cm off the holder
after the cutting...
rear bumper back on
Number plate surround
as it is quite old, the matt black number plate surround turned grey, so i decided to paint it matt black to freshen it up...
EXE-Crew (Shaun Chiew) Winton Trackday 21st November 2010
2 days nonstop preparation after i landed from 7 hours flight, and only 2 hours sleep in total, plus 2 hours drive up to benalla, winton raceway... all that was well worth the long awaited 'winton fix' that i have been craving since May 2010... especially this time i will be back on RWD cars since nov 2008, which ended my 350z track journey.
my eyes got teary and happiness was indescribable on my first slide / oversteer / counter steer... and the 2nd... and so on... got i love the feeling of being fluid on the corner... i miss it. yes i admit i have been doing some trackday back in indonesia but Sentul circuit is more of high speed, braking and consistency like Sandown circuit if i have to find a comparable one in melbourne. but Winton is the whole other league... its technicality is hard to match... pity the tarmac degradation and lack of smooth ripple strip still hasn't been improved since the last 2 years i have been inactive...
anyway first, here are the best lap video:
and here are the video of the mistakes (highlights):

my personal best on the day was 1:51.2400... so i am still 1 second off my target / estimation of 1:50s... heck even my 1.3lt micra is still faster than this E30 at the moment... it is not the car for that i am sure... i just need to feed the throttle slower and smoother... better driving will be my next move... the rest of the participants Personal Best: http://www.natsoft.com.au/cgi-bin/results.cgi?21/11/2010.WIN.S1
being no LSD and stiff rear, the inner rear tyres always smokes up every corner... and that is due to either me trail braking or planting the throttle too early and too much...
i am starting to get the hang of it by session 3 and 4, however the street tyres start giving up towards the end of the day... will save up and invest on better rubber on the future.
the car at the moment is very front heavy. it is already was from factory and me stripping it made it worse , but i need the weight saving to get better power to weight ratio... the weight of the car stock was 1280kg and making around 125kw at the flywheel from factory when new... lets say now just around 120kw left, thats 9.375kw/100kg... i managed to strip around 57kg (17kg tar, 20kg seats, 15kg spare tyres, 5kg door trim and others) thats around 1223kg atm... 9.812kw/100kg not bad
now removing the rear swaybar helped the rear outer trailing arm to drop and adding grip on the corner... since the big brake at the front made the car dip even more under hard braking, lifting the rear and kick the tail out on the corner entry...
the wing helps abit, but the most significance place was the left sweeper... it really help settle the rear altho i think i could do with more angle of the wing... redrill the mount for next time!
the tyre pressure with these 225/45/17 are best with 30psi for me... i could be very wrong but i think it gives me plenty more grip at the rear and higher mid corner speed...
these are the photos, thank you for Christophe Delcourt (Dens), Vyets, and Daniel Chin-Wee (c2888):
