i can`t finish the trolley without the cement harding any tips?

the first trolley (1min 16sec)? because there is a second one after the first. i finally got the first after many many tries, and i still haven't done the second one.
to make it in 1min16, i almost never slowed down. you must go very fast and be careful about the turns. there isn't really any trick (well, i didn't discover any). the two places where i braked were: 1.in the huge slope at the beginning that brings your speed up to 140mph and 2.in the mega turn near the end (the one with the last green "seed of strength")
speaking of the little green seeds called "seeds of strength", do not worry about them, you can get them later. to grab the seeds, you can go very slowly. the only requirement is to finish the race. once you've finished a race, no mather how many time you took (1min or 10mins), the seeds you grabbed in the race will be yours. and you don't have to get them all in the same race.
and finally, the second trolley i was talking must be finished in 1min 11sec (or something around that). but it's impossible with the actual trolley. you have to find a way to make it lighter; way that i still haven't figured out yet.
that's all i know so that's all i can tell.

you gotta make the light alloy!!!! then that *bleep* makes a lighter trolley. look up on a walkthough how to do it i dont remember.

You Get the two mudball surprises. One is on the top of the steam flow furthest to the left on the top horizontal pipe. Its on a hanging platform.

The second one is further left, at the chain.

You wash them, burn them then combine them to make a light alloy. Then talk to the guy closest to the combining machine.

1^st:find the 2 mudball surprises(i forgot where they were)and wash them in washing machine.

2^nd: Put both of them in the burning machine.

3^rd: Put both in the combining machine

A bit pointless repeating what someone else said, don't you think?
