I thought they had a solid front axle and a floating beam suspension on the rear(might as well not have any)! Don't really have them here in the uk so not 100% sure on them. An oval racer is not the best example of needing dynamic suspension. Oval recers tend to have a different setup on either side of the car as well.
But out of the 100's of forms of motor racing and explanations of why flex is traditionally thought of as undesirable i had already bet money that someone was going to spend their time trying to find rare examples of racing vehicles that use do use flex just to prove what i said was wrong.
What i was saying is flex tends to be used to compensate for suspension or geometry deficiencies but ultimately if you can control the forces accurately it is better. If not 90%+ of the motor racing world has got it wrong and a toy manufacture has got it right.
