I've breaked my arm before I've made this scene, so somethings are difficult to fix... About the ''stucks'', they happen because I used the brush to make the second part, and the brush have bugs
try to make something using boxes and the truck will run well
also... check out my new scene, this is cool and have a difficult bridge
I gotta inspired by your low rider, but I don't checked your suspension
I tried a lot of combinations: the actual, a piston-moved hidros, a hidraulic hidro (with water, but have much lag) and a rotating hidros (a gear spin fast and hit the suspension, causing a very high bounce; but, after some bounces, the suspension wreck)
Oh, a susgestion to your GT car: you can make a movable truck, and a track, would be cool
Good. I liked the paint of the car, yellow and black match a beautiful color
Well, the visual is OK, but would be cooler if you boost the car power
Final note: 7/10
Oh, I don't know about the springs. This may cause a little trouble...
And I like very much the Polara, next to my house a guy have a green Polara with a blower on the hood. The power : 500hp
Actually my dad's Scenic its black and 2000 model
He will buy a marine-blue 2004 model (the car in the scene)
