don't be shy with with the baggage!
I have carried:
1 X OEM nissan seat melbourne - sydney
1 X velo race seat (thanks dane) melbourne - sydney
1 X 19 X 13inch GT500 TE37 wheel from tokyo to Kyushu on the 7am commuter flight. that one got some looks as it came out on the carrousel.... especially since I was the sole white man on the plane full of japanese busness men
Plus literally hundreds of kilos of parts (inc OS twin plate, gauges, EBCs, cam gears, cams, etc etc) from tokyo - sydney.
hey, they may give you some funny looks but i've never been shut down yet. though once the wanker at melbourne tried to tell me I couldn't take my umbrella with me.
swaybars wont be too bad as at least the standard ones are nice and light (can't say the same for the whiteline ones though )
