[CONTEST] Perfect Suspension! (My entry 12x12 hemtt)

Build a vehicle with your own suspension system so it can pass the course under 60 seconds in the smoothest way possible.

Rules:
-Must be derivative of this level
-The vehicle must be propelled by wheels (using motors or other engines). No flying or warping. Thruster, rocket, fan, and emitter must not directly power the vehicle.
-No editing the track, start/finish line and level properties and environment other than the vehicle.
-The vehicle must be built on the left of starting line. (Laser)
-The wheel must be placed on layer 2 and 3
-Must drives automatically (no rc controlled) however, you can use AI to control the vehicle for speed if you prefer (lua is only allowed for this)


-(IMPORTANT! IHAVE TO USE CAPS BECAUSE ITS SO IMPORTANT) Never, ever, ever edit or delete the scoring system (in the middle of example vehicle, consist of red plastic beams, green plastic box, rubber bands, one linear servo, one ct servo, and one lua script (IMPORTANT)


-Don't interfere frequency 1001-1003 (used for scoring systen)
-No OP bug and/or frequency bug
-Must allow derivatives for inspection
-Delete my example vehicle (of course, except the scoring system)

Scoring system:
Scoring is based from smoothness and speed
When the vehicle bumps, the green box oscillates. The more the green box oscillates, the more score you will get (of course, lower score is better). If you finish the course in less than 60 seconds, you will get bonus (-1 score for 1 seconds). Otherwise if you exceed 60 seconds, you will get penalty!

The final score is average of top 10 scores.

Deadline is August 10th, 2016. Have fun!
