I know the car is pretty light as is it, but is there any chance of losing any more wieght to increase speed? I cant think of anything to remove that would make a substancial difference.

 

Change the battery to a low weight battery...40lb loss.
Remove the exhaust resonator (srt-6 not sure if limiteds/bases have one)...10lb loss.

Carbon Fiber driveshaft? Lighterweight wheels? That's about all I can think of off the top of my head.

 

I suppose you could remove the backseat.

 

I actually lost about 30 lbs when i got my first crossfire, I felt faster... LOL

I have no idea about anything else, maybe your tire repair kit in the back. You don't want to use that crap anyway. If you have a flat just get it towed somewhere. That's what I did after I used that crap for the first time. It does work, it just leaves a mess inside the tire and cost about as much as a 35 mile tow to replace. 54 dollars if I remember right.

 

There's really no way of lightening the car without destroying the daily driver appearance and functionality / comfort...

There is VERY thick / dense padding, sound deadening material under the front carpet.... Total weight savings would be somewhere around 40-50 lbs....

 

Carbon Fiber Driveshaft - save 10 lbs
Braille CF Battery - save 40 lbs
Tillett B2 seats with padding, no sliders - save 60 lbs
Toss out emergency kit - save 5 lbs

This gets you close to the torque to weight ratio of a 350z. Of course it will only cost you $2500, but hey, you asked

Of course, you can break out the sawzall, like they did in SCC:

They used weight-saving techniques to bring the 0-60 time of a Sentra SE-R from 8.6 seconds to 5.6 seconds. Vroom!

 

lol, okay, thanks. kinda what I figured.

 

Other ideas:

Remove passenger seat.
Remove radio.
Go with a smaller gas tank (some weight savings) that holds less gas. Gas weighs approx 6lbs/gallon. Only putting in 4 gallons = 24lbs vs the heaviness of 15.9gallons at 95.5lbs.
Remove a/c compressor to reduce drag on engine.

I'm sure there are lots of other ideas.

 

Maybe it's just me......but I think it's much easier to just put in less gas than replacing the tank!

 

Knife edge the crank and lose some weight yourself.

 

remove the doors like a jeep! and take off the hood and hatch bumpers... who needs em fenders??? one guy ran the dragon with us without em... seat carpet dash airbags headliners interior trim pieces grille headlights exhaust glass, ummm hell lose the battery all together ... yeah that would be one light xf... not very street legal or aerodynamic but light none the less!

 

On a Jeep, it's just 4 nuts that unscrew and the door s are off (YJ, TJ, & JK series, not sure of the different CJ variants) Something tells me that these doors aren't so easy........

 

im sure they are close to that easy... after all chrysler and jeep are the same company, maybe an extra screw or two lol

 

I don't know if there's any structure in the door which can be removed (ask HDDP) - this will obviously reduce stiffness/crash effectiveness etc.
Remove all the EPP under the trunk floormat (and tire kit like others have said) - won't gain you much weight, but you'll be able to carry more.
Plastic shield under the engine.
I'm assuming you want to keep the car looking nice - so removing fog lights may not be an option.
Nitrogen in the tires
Remove a lot of the wiring to things like heated seats - powering the passenger seat (just put it all the way back).

 

I was just reading on another forum of putting in lighter lightbulbs. geez-us.

 

Paint is pretty heavy....isn't it?

 

Helium in the tires! If you don't mind the dangers of going out in a blaze of glory....hydrogen in the tires!

 

In all honesty I think this topic is ridiculous. I am sure the gain in speed would not be worth the mods by taking apart a piece of finely crafted engineering design. But if you find the need to do such a foolish thing then this link may help you destroy your car from it's original beauty.......

Have any "gold" fillings removed from your teeth, take a laxative, remove all jewelry, and brush your teeth. Take some ipacac,
donate some blood, bone marrow, and a kidney,
Then cut off all your body hair, and drive NAKED!

 

Okay, a little over kill guys. I guessed there wasnt much to lose based on how small the car was, plus I dont wanna lose comfort, but I figured it wouldn't hurt to ask. guess I was wrong.
