Default weight reduction worth it?

Tomorrow Im going to the track for the first time, I've taken out all the mats everything in the trunk including the jack, spare and spare cap. Is it worth the effort to take out anything else like the front seat?

Hell yeah.

While the back seat does not weight much, all the bracing below it does.

Most definately.

For approx every 60lbs you remove, you gain a tenth (0.1) down the strip and this has the same effect as you having an extra 7whp approx.

Of course, the lighter the car the faster it will be and the easier it will be to control. You can spend less time fighting inertia, and more time fighting your resolve.

One of the benefits of weight reduction would be that you have less of a chance of breaking something in the driveline. Seats and trunk stuff are the basics. For your first time at the track though you should be focusing on more important things.. lol

There are a lot of areas to shave weight. Even with extra bracing, heavy fmic, big brakes, full aftermarket stereo (all four doors, two amps, cap, wiring), harness bar/midframe brace, fire extinguisher, and two sets of Takata four points harnesses my WRX is 2970. Even on inferior tires I was faster than STIs at the track (racetrack, not 1/4 mile). Weight is everything. I'd love to gut the stereo, AC and zillions of other things, but it's not a dedicated race car. The front stock seats are pigs.

it depends what all you take out of the car if it's worth it or not. take out the bumper beams there heavy but if you crash you screwed if the insurance company finds out.

LOL- I should post pics of my interior....

I've removed nearly everything from the front seats back... I just installed a bulkhead cover, carbing, to clean things up a bit.

Weight reduction helps, the car is more responsive to your inputs and you can make better use of the car's stock and modified capabilities.

I really had no intention of essentially gutting the rear of my car, just kind of got addicting lol-

What idiot would remove bumper beams? Common sense seems to be harder and harder to find.

He's right. Those pieces under the seat weigh very little and are actually functional. Mine are still there and yours should be too.

The passneger seat in an 02 weighs 48 lbs. I remove the passenger seat, rear spare tire/jack, etc.., and rear seat. The spare tire alone is 22lbs, with everything basic I lose 88lbs total. Then I've save another 15lbs in aftermarket engine mods. My ET doesn't change noticeably because I'm not the most consistent driver, but my MPH seems to improve noticeably by roughly 1mph, regardless of ET. I hope to get back out when track conditions are better and cooler, but I ran a 12.6@109 best at full weight, and a 12.70@110 best with the weight loss. That was later in the day though, when clean launches were tough. The trap says more of it than the ET though....

Well you don't even have to remove it completely. Replace it with a JDM one. Their lighter and still maintain some safety if your worried about that. I noticed that a lot lot of aftermarket parts not only improve things like handling, power, etc but their lighter too. But I do agree every little thing counts. Spare tire, jack, seats, plastic stuff, door cards, you can even do things like lightweight crank pulley, etc. All depends on how much race you want. I try to do as much as I can to mine but I still want comfort and style which means my car will be a little overweight, but see still fits in with others
