Thread: roll cage/ gutted interior

Just curious who has one and what their setup looks like also wondering how light you can get a grand prix I wouldn't think you could take more than 100lbs out

if you take out all of the interior pieces you should save a few hundred pounds, no dash, passenger seat, rear seat, door moldings, roof liner, floor carpet, speakers, spare tire, race steering wheel and drivers seat
how extreme do you want to go?

putting a cage in the car is doing the opposite of losing weight, so you're kind of going to run into issues there.

i, however, do plan to do a half cage in my car. just wrap a bar around the back of the front seats and connect it to the b-pillar and the floor below it. after that i was going to put a nice x-brace in the trunk to connect the rear shock towers. then if i felt like getting even more frisky i would make a front strut bar that also connects to the firewall to form a triangle. going even further you connect the upper portions of the frame rails on the front of the car to the middle of the lower cross beam. there are tons of ways to stiffen the chassis without adding a full cage that in most cases will be completely useless.


however, as far as gutting the interior, you could lose a couple hundred pounds. the seats are fairly heavy. removing portions of the dash may help out your goal too.

Well if I do it I figure its a all or nothing thing and I don't wana do it unless it makes a noticeable difference

I can think of a few more things that are kinda extreme

delete the battery and boost the car every time you need to start it, will run with just the alternator
a/c delete, you won't need to be kept cool for a 1/4 mile run
no rear brakes, 16" black steel rims

I want it to still be able to drive on the street I already plan on the ac and hvac but I thought about plexi glass Windows in the back and wind shield I still want the front Windows to go up in down id like to keep two seats cause what's the point if I can't show the car off

how do you get rid of the subframe isn't that needed?

He said he swapped his steel one for the newer aluminum one.

oh gotcha thats not a bad idea

You can get rid of the subframe if you make a nice tubular one to go in its place. That would shed a ton of weight and be awesome.

I don't trust an aluminum subframe either...

This has most of this stuff already covered...

cut the trunk floor+ spare out and mount an aluminum plate for a floor section, drop the gas tank and install a 10 or so gallon fuel cell with a decent external flow pump would help with weigh, speed holes in everything

Let's say I could get it around 3000lbs what type of difference would that be in the quarter

every 100lbs is 1\10th of a secondish

Cole going to ultra racecar status?

Race Battery would help with the streetable thing...

cole a main hoop with 2 down bars would be bare mininum for tech at the track? i think go 8 point like a boss
