Congratulations for the realization. shame about the sound that doesn't give credit to the zytek V8 engine.
I know the model of this LOLA very well because I am a hillclimb enthusiast, I made a mod of this car based on the 3D of race07 and I can tell you with certainty that your 3D model does not have the correct measurements (bigger), just open it on the CM near the other Kunos Formulas and you will notice it. If I can give you some advice, take the 3D of race07 to have some references on the real dimensions. I hope my comment was helpful. Good work
