I think the problem is, you need to stiffen the suspension a lot, strengthen the body a bit and maybe increase the grip slightly.
I really should have made everything more clear, because everyone seems to misinterpret what's going on. The videos do not reflect anything that is anywhere near finished. They were only very early tests to ensure that I had scaled down the wheels correctly. In the videos, the Covet still weighed over 2500 pounds, and I would obviously want to get the weight down first before I do any of what you suggested. As far as the actual project is going, I've gotten it stable at half its original weight, and Slayersen is working on applying node scaling to each individual part. We've both been busy and I've been gone for a while, so progress is a little slow.
Oh. Well that is a bit embarrasing. Should probably think twice before saying that next time. Anyway, just keep that hint.
Nice project! I always thought that this would be a good idea for a mod, I'm happy someone is finally making one!
