You forgot the spare tire to.

 

Don't take it personally rakoom. Actually besides the hilarious and obviously joking responses, I think your question has merit.

I think it's possible to match, for example, a stock 350z in acceleration by losing 150-200 lbs off the car. You'll end up shaving time off the corners too. It just costs money to do it in a way that uses high tech materials, but it's not a meaningless endeavour - just an expensive one.

 

I'll definitely second that!

 

Guys, I'm not trying to be a downer here, but unless you want to butcher your car like HDDP did for racing, (no offence Derek) you would probably have to lose 800lbs in the Crossfire to beat a Z car in the 1/4 mile.

350Z runs 14.1 sec 1/4 mile
XF....runs 14.9 sec 1/4 mile
That's going by the old theory, lose a 100 lbs. lose a 1/10th of a second.
Still, losing weight is always a good idea for performance for sure.
Ultra light weight wheels, mini battery, possibly an aluminum exhaust? These mods wouldn't make you think you're "roughing" it when you take your car out for a spin, but I bet you it would probably feel more nimble.
I've said it many times before, even though a Limited/Base car isn't blessed with gobs of H.P., it still has lots of low end torque, and the biggest thing holding the Crossfire back in the 1/4 mile, (or just 0 to 60) is gearing. With a 3.73:1 or 3.91:1 differential, the Crossfire would be a low 14 sec. car.
Sure, it's still wouldn't be a world beater, but more in keeping with its competition. Face it, we really don't need 150mph+ capability!
And it goes without saying, the SRT is still the REAL drag racer in the family.

 

I know how to lose anywhere from 110 - 135 bs, however, it costs a bundle.

Get a Divorce!

 

Is there any donor car that you can grab lower ratio gears from? I'm guessing the suspension too is shared with the SLK.... Btw these cars have lsd's right?

 

A long time ago, I think someone posted that they found a Mercedes that used a 3.55:1 gear ratio, but whether or not it was the same "type" differential the Crosssfire used was not made clear.
Nobody, produces a "lower" gear ratio "ring and pinion" for this style differential any longer.
And no, Crossfire's don't come with LSD, not even the SRT. But an aftermarket unit is available.
Tealcamaro55, I use to have a 94 Z-28, 6 spd. "chipped" so I have a pretty good idea of what kind of performance you're accustomed to.
So unless you're going to be content with having a car that's probably (at least) 2 seconds slower in the 1/4 mile, than your Camaro, then you may want to consider a SRT.

 

I totally agree.

I'm surprised no one mentioned a carbon fiber or fiber-glass hood. Smaller and lighter rims.

A long time ago, I was "forced" to own a Mitsu 3000GT-VR4 and it was a serious modify/track street legal car. For those familiar with that car, you'll know it's seriously heavy. We replaced the steel parts on the body with custom moulded parts made of lighter materials and put tubular cro-mo space frames underneath to ensure that rigidity and integrity wasn't compromised.

It can be done and it might cost quite a lot, but if done right, the results won't be trivial.

 

Now that made me laugh out loud.
Although 110-135 pounds ...she must have been mmmmmm hot ??
