the front bumper support weighs 12 lbs. each bracket about 1.5 lbs a piece so id say you lost 15 lbs by removing that. and when you hit something you will really mess up your front and rear.

 

almost on E

EDIT: more like an 1/8th tank

 

ive thought about that, im serously considering just making this thing a track/occasional street car.

its not street legal, so the first time i get a fix-it ticket, im making it a track only car.

 

id say mine weighs around 2550lbs give or take a few lbs , s4 base se model

removed - ac , ps, airpump, egr, acv, vacuum rack, 5/6 ports and actuators, front speakers, coldstart, storage boxes, rear rug and mat , charcoal canister, other charcoal canister under passenger headlight

also - lightweight rb flywheel (reduced 7lbs from stock)

future mods include - single exhaust (reduce weight about 25-30 lbs), and still thinkin about what else i can do

edit - take off about another 10 lbs if i take out my jack/spare tire

also about the gas thing, is the car's factory weight measured with a full tank of gas ?
