I am almost ready to start offering some GV style lip brake duct inlets for sale. I have a design that is working well on my track car but would like to get one more track day of use before I decide they are durable enough to sell. I do not live with my car right now so development has been taking much more time than it should. The picture below is prior to me fixing the gap at the top (I measured wrong on the initial test piece), the duct currently installed on my car does not have a gap up top. I will get up to date pics as soon as I can.

Anyway, please comment here if you would be interested in a set. I also am not sure what would be reasonable pricing wise, feel free to chime in on that too.

Also, if I do start selling these, do I need to do anything with regards to paying this forum?

 

Did anything come out from this post ? Did you have more pics on the GV lip intakes
