how much of a difference on the clock does taking out the passenger seat and all the carpeting and the little container things behind the seats in my 93 del sol

 

Not much I know that.

 

It makes a difference.

 

I would take out your spare tire, jack, and passenger seat but only at the track. It's not worth removing the carpet.

 

Carpet does not wheigh much, but if you really want to do some work it all adds up.

 

If you take everything out its worth it and you will notice a difference but if not It's not worth it.

I started by just removing the back seat. (no real difference)
Removed carpet paneling tar jack spare etc. (noticed a difference)

 

one tenth of a second lost in the 1/4 mi for every 100lbs removed is fairly average. not a big deal unless your running around in something with considerable weight already like an f-body or mustang. in a civic there isn't hardly enough weight to remove to improve your times that much.

 

i hear removing the tar under the carpet u can notice a difference in weight. my freind ran 13.5 on slicks with a stock gsr in a 94 ex coupe with all the tar out and swiss cheesing the rear and front bumper supports and stripped completely in the rear half.

 

15" lite weight wheels will give u instant performance

 

Rough Estimate
Tar; 10 pounds
Bumper support swiss chesse; 5 pounds
back seat; 10 pounds
Rear Panels; 10 pounds
TOTAL; 35 pounds
35 pounds isnt a huge difference so I wouldent credit his times to his "striped interior".
It all adds up but if your going to drill holes in you bumper support I would hope your
freind did the normal things like ac and power steering removal.

 

everything adds up man.. like they said .10 second is what your looking at.

 

take out the roof bracket in the trunk. I heard this weighs like 50 pounds, an if you don't store the roof in your trunk, then you don't need it anyway
also- run topless at the track

 

i'd say its only worth it if you are a hardcore racer. if not, all youre going to do is make your car noisier on the inside.

 

Its only .10 seconds if its 100 pouds in wheight reductions.
All I was saying was that if your going to take it as far as too drill
holes in the bumper support that you should be a serious racer.
Strip the easy stuff first.

 

That'd be a big difference, but wouldn't it mess with aerodynamics?
