I think the front suspension needs to be upgraded to an independent suspension, the car doesnt handle very well on mc phearson struts and also, the front splitter or the hood needs to produce downforce because i checked the files and couldnt find the lines for increasing downforce and also, the acr wing needs some more reinforcements since it kind of deflects at about 200mph, overall, one hell of a mod but yes, still needs some work, bigger, wider wheels would also help
