Phew!
After a big issue with the previous model I've had to rebuild the car from the ground up. The car model can now be aligned using data (from within CM) which surprisingly a fair amount of cars even from Kunos cant.
Based on a new chassis the car now has vastly improved tyres.

New higher quality rain/fog light

And as you can tell from above a working rear fan

The physics are also done and I may release a test mule with no fairings for data feedback soon.
