Can I ask what grade Aluminum you will be using? There really isn't such a thing as "Aircraft aluminum". It's more commonly used in marketing schemes to make you think your getting good stuff. Aircraft use all different types of aluminum, but for structure mostly 7075 grade is used.This is a feeler only to see if there would be any interest in a B5/.5 Front Upper Stress Bar/Brace. Price would be around $150. Would be made from Aircraft aluminum and using Audi Factory endlink brackets,
No drilling required, just bolt on.
