Ok, I added some soft tires (kinda):

I guess I should have explained what I was doing. I look around here and I see all these weird bridge designs that either approximate real ones or are completely random. So, I decided to go to wiki, look up truss bridge designs and implement them here. Then I realized I could test how well they handle stresses, so that's what I did. Is there a problem ? Maybe you'll learn something about real truss bridge designs. Or maybe you just won't get it at all.

good job, it probably is the fastest spring engine car, at least that I've seen. Even tho I've only been able to get it to 570 or so before it explodes, it is faster than the one I made (unless you scale it up, and then it can reach similar speeds). 10/10

Glad you like them, I was beginning to think I shouldn't have posted them. I got all the designs from wiki, so they are real designs.

Looks good, but why not put a throttle on it, instead of it being connected to the crank shaft ? It may or may not work this way.

Great work. Works well, but is a bit difficult to start, I have to give it plenty of throttle, and even then it is hard. Still, it works very well, so 10/10

Nice work. The engine works very well. It's a bit unusual and cool because of the double collision. 10/10

Cool engine. I don't know anything about good gearboxes tho.

Really cool concept, the only problem is that the engine bumps a lot and doesn't go very fast. 9/10

Dunno about your memory but this t2k5 has NEVER submitted a single scene, so I need a bit more proof than your "memory".

EDIT:
I would also like to mention that I downloaded the track from datslok, and that he did not credit someone else for it. So, don't blame me if it is wrong, I did my part.

I think I see what was done now. datslok took the track without giving credit and pasted two of them together to make an even longer track. I suppose I should change all the credits to phunbox1 (T2k5), alright so be it.

thank you mr random, I have just helped your ratings too
