I'm not sure that it is all that CG claims (their claims are pretty spectacular), but I used one of these on a track day recently and it certainly is a useful augment to the inadequate seat bolsters when enduring high lateral G. I like the fact that once installed you have the option to use it or not without having to remove it completely. Good luck with the sale
