I run several Auto Cross events each year and I have one on Sunday. Five newer Mustangs in my class.

I remove things like floor mats, spare tire & jack, CD changer in the trunk, empty the glove box and center console. I even empty the washer fluid tank and remove my garage door opener.

I'm thinking about removing the under hood liner. Anyone have an idea how much it weighs?

Also, if I remove the plastic cover over the radiator, will that change the cooling flow through the radiator?

I have to run about 5/8 tank of gas otherwise I get some hesitation around tight corners and slaloms.

I thought about removing the radio and wiper arms & blades, but those are a pain to put back.

Anything else I can do to save weight?
