This Pack contains 2 versions of the model:
A detailed version
A Roblox Ready version importable into Roblox Studio without issues.
Of course due to the strict limit of 10k tris on Roblox Studio the Roblox Version has been reduced in terms of details, expecially the grills.Also, for the Roblox Version I didn't include brakes as many chassis used in R.Studio already have them and the mesh may go in conflict with it.
Both models do not have interiors.
The poligons and tris specified in this page refer to the Detailed Version.
