Originally I couldn't find anything about movable suspension on a 'junk toy grade car'. If i had a pan car or something 4 wheel ifs, there's TONS of ideas...
Started with a brass L shape that mounts to chassis, added a tube onto that. Slid a brass rod through tube for pivot, mounted brass rod arms on pivot rod. One arm rod extended to where servo arm sits, necked down an area fo hold string. Added side plates to pivot to keep arms centered over knuckles. Made some brass pins with smooth bottoms that push on top of knuckles down to lift chassis.
Brass hingey thing ties to chassis at front steering gearbox mounts. Equipped with knuckle pushrods, and side plates to keep it over knuckles. Some mechanical advantage, string, metal gear servo.
Blue vertical servo does steering.
Black laydown servo does attitude adjustment
Also pinned the draglink onto the knuckles so if can't pop free with the vertical travel
Pfffftsss
Wrrrrrssssssss
