Hello everybody!
Sorry if this is the wrong place to post this, it just has to do with Motorsports so I thought here would be a good place!
Just recently obtained a performance model 3 and was hoping to take it to the race track as soon as possible. I strongly prefer to use a head and neck restraint and unfortunately, unless you purchase a Simpson Hybrid S for about $1000, there are no safe, tested HANS devices to be used with a 3 point belt system.
I reached out to Schroth Racing, a well respected name in Motorsports who offers certified 4 point belt systems that can be used with stock seats, and currently they have no current plan to release a system for the Model 3. However, a few Model 3 owners (one of which is winning many autocross events!) are using a BMW Schroth harness with the stock Model 3 seats to great success. I reached out to Schroth on what could go wrong by doing this. They said that by far the biggest concern is the seat back strength which they actually physically test on the cars before they release a model for that car. Since, I am a bit of a cautious person this worried me a little bit. I know there are some actual tesla engineers here so I was hoping maybe I could get some type of confirmation on the seat back strength. I believe the loading is in the vertical direction and is dynamic in the case of an accident the harnesses kind of slam down on the seat back, keeping you very secure. In most modern cars seat back strength is no issue, but we are talking about a huge amount of loading here.
If anyone knows of a better place to ask this question and potentially get a more accurate answer, please let me know! I would love to use this car to its fullest ability with minimal modifications and maximum safety. Thank you so much for reading!
TLDR: Can the stock Model 3 seats withstand the loading force applied in an accident when using a bolt in 4 point harness and HANS device?
