Thanks for quoting the marketing material from the prospective vendor btw that's really objective stuff.
Definitely helps with wheel hop. I have witnessed it first hand with my car as well as other owners on both 335s and M3. Here's a video of another user with an ESS Supercharged M3...
I can't tell if the last sentence is sarcastic?
I would recommend driving a car with the brace on before coming to conclusions. I have had a ton of mods and $1k (Including installation) is very fair for what this product does.
