Fenders are 2lbs lighter front bumper will allow better airflow for the intercooler when I go fi and I have the 10series so ignition silver main reason I am considering this is because I got damage from a storm the other week don't want it on the insurance so planned on fixing it myself until I got the quote for painting it's 1200 to have a single fender painted oh and the cf fenders are 10mm wider so bigger tires haha
