dun DIY with aluminium sheets lar... i think will look like ah beng... n one thing u have to make it very balanced.. then onli it will spin nicely... wait it spin fast n slow.. then de thing goyang in n out... look very cheap like dat... hahaha
if the aluminium sheets are securely placed/joint on the bearings/spinning mechanism, then it wont goyang la.... but partly true also la...must think of heavier object la. Coz if lets say, you are flying on Kesas @ 100kmh... if the thing fly out then people might think its a newly polished UFO hahaha
actually... it does look good if your rims are proportionate larger than normal (ie if use 16in on Kancil) will look very nice... with spinners too whoaaa... something different la
