here is my mini - old photo but it looks exactly the same now
improvised block tyres (re cut into worn tamiya tyres)
rear shocks are standard friction things, but the front uses DELTA oil shocks, taken off an old yokomo dogfighter- no idea what the shocks are originally from - maybe a 12th scale.
Heres one of the steering knuckles... I couldnt afford alloy ones so beefed up the normal ones since these take a real pounding as Im sure you know - those long ball studs put a real twisting force on the ends.
