I’ve been wanting to do a vented M3 Hood conversion for quite some time now. I know most buy the carbon fiber or aftermarket versions and as much as I want the weight savings I can’t live with the gap between the kidneys and the hood. I recently bought all the components to make a custom hood but because of the complexity of welding steel and aluminum he is recommending to purchase a steel hood and weld it to steel. I know the hood will weigh a few pounds more I’m not sure maybe 10-15. Is there any downside such as steel producing more heat? I am supercharged and am hoping the vents will do more cooling. Any input would be appreciated.
