Always willing to help out others in our community, our crack team of designers decided to help out MobiusCyka with their latest project. We solved the issue at hand by making several tweaks:

-added a front lip and side skirts to stop the front end of the car from lifting -moved the engine a bit forward to improve weight/downforce distribution and to make more space in the driving cabin
-slight adjustments of the rear spoiler
-added AC and a cutting edge hifi system
-display vehicle is in the new Epic Engineering ground projects livery.

I hope this build helps with the issues at hand. In case there are some persisting problems, make sure to let us know.
