There will be a small update as soon as it gets approved. If anyone wants it earlier send me a PM with an invoice number and I will email it to you. GetGroundHit(out hit); and WheelHit struct have been updated to be as similar as possible to the GetGroundHit function and WheelHit struct from the inbuilt package + some other minor API updates. Improved spring / damper stability. Some tweaks to the demo scene. Bug fix for the ray length calculation (performance update).
