Lowering a vehicles weight as a low cost aftermarket modification

The most cost effective mod there is! Usually free. 100lbs lost = .1 off of the quarter miles (equivalent of 10hp) and adds 2% more fuel efficiency

Your vehicles weight plays an enormous role in how well your vehicle handles/brakes/goes. Obviously an engine that makes 200hp in a car that weighs 3000lbs will be slower than an engine that makes 150hp in a car that weighs 2000lbs. With all other things equal. Some weight reduction mods cost some coin and others are totally free except for your time. I’ll start with the most beneficial:

Lightweight wheels: For off the line performance lightweight wheels are well worth the price. If your stock wheels are 22 lbs and you replace them with 12lbs, thats a total savings of 40 lbs! Rotating weight is the best area to shave pounds off of.

Lightweight flywheel: Your stock flywheel weight will vary from engine to engine, so do some research to see if the added cost is worth it, but if you’re replacing the clutch it’s not a bad idea to splurge. This mod will greatly increase the rate in which your engine revs. Getting you to the powerband much faster. Some people experience chatter with aluminum flywheels (fidanza, clutchmasters, spec), a billet steel (exedy) won’t, but they weigh a little more.

Gutted interior: It really depends on what you use the car. Dates will not appreciate this mod! It involves taking all the interior trim out of the car. All passenger seats, carpet, door panels, seat belts that are never to be used, dashboard (most of the hardcore guys make carbon fiber sheets and install aftermarket gauges), cup holders, radio, shifter trim, etc. All together these items can range from 80-200 lbs of savings. Remember 100lbs= .1 second off of the 1/4 mile and 2% in mpg.

Spare tire: For a savings of 20+ lbs remove the spare tire and jack and replace with a can of tire gunk.

Air conditioning: Removing compressor,lines, evap tank can equal 30-50lbs

Carbon fiber: This is can be a purely style or racing mod. There are various carbon fiber car-body manufacturers, I’ve always been partial to VIS. They can cost alot for a quality piece but at the end of weight reduction it can give the added edge over the competition. Hoods usually save 30lbs, fenders =10-15, trunk/hatch =10-60 (hatches save more).

Lexan glass: Automotive glass is heavy, lexan glass is not. Primarily used for track only cars, replacing all glass with lexan can save 100-200lbs.

If you do everything you can to reduce the weight, it’ll be easy to drop .3 off of your quarter mile and maybe even pick up an mpg or two.
