I have to manage the heat in my brakes just a bit more now.
Thanks for the info. I will follow the DIY thread on the self fab/install brake duct.
I will have the same issue you have now as I have the Challenge GTS front lip (without the brake duct holes). My way around this is creating vents that are angled and hang slightly lower than the under carriage profile.
