has any one ever used aluminum brake lines? trying to loose some weight.
-
I don't think you will save much weight. All my lines are braided SS with aluminum fittings.
The weight is not that significant of a savings.

that is true its not much but i need to loose alot of weight. i have talked to people that are over 100 pounds lighter than our car with no lead.so i need to get rid of every pound i can get. if i can loose 1 pound i do that 10 times thats 10 pounds
thanks cody

Understood. Lose things like the tach and gauges (2 -4 lbs). Look at lighter weight wheels (if you don't already have them). The aluminum hard lines will save a little. You will still need braided lines to the front calipers. Lay off the meat and potatoes. lol! You have the right idea; cut back an ounce at a time if that's what it takes.

i think the rims will be after she get faster still have 3 full sets of strait bassets. you know when i said over 100 pounds thats with out driver and lead
thanks cody
-
Somebody's scales are way off!! I'm thinking it is who you are talking to..100 lbs is not going to happen..all the required components HAVE to be there. I can see 10-20 lbs, but 100???

Was it a used chassis? Just wondering that maybe someone filled a few bars, but i agree 100 pounds is alot to be heavy by

Sorry to go slightly off topic, but the guys at Aeroquip advised against braided line throughout, can cause a spongy feel in brake pedal. Probably wont affect Steve's racing style, but they advised against it for regular racing...and that's from a company that could have sold alot of $$ worth of parts, so I will go with their advisement.
How did you weigh the chassis? If you didn't use all four scale pads, it could be off. If used all 4, what were the percentages? That would let you know if someone filled the left side with lead or something like that
-
i did use all 4 scale pads. i had it on 4 jack stands subtracted the weight of the the jack stands and got my total (270 pounds). i did not check what each corner was. 600 says that a new chassi weighs 275 pounds. i was sure that there was lead in the chassi but it weighs what 600 said it should.
for those that say her car could not be that heavy with out driver no lead full of fuel her car weighs 1198 pounds. i have talked to lots of people that say there car is alot under that.
thanks cody
-
My 34 coupe is 1086 with no driver and no lead with heavy wheels and a beadlock.
How much does the seat weigh? Nice, big containment seat will add pounds, but they are necessary pounds
How much does the driver weigh?
-
yes she uses a full containment seat but as you said she will not race with out it. shes tall and about 200 pounds ( she would kill me if she read that). i also have the heavy wheels but no beadlock. i did do some things wrong when i went through the car last year but i do not thick it was 100 pound of wrong. if i could loose 50 pounds off the car i would super happy.
thanks cody
-
If I could lose 50 pounds off of me I would be super happy!

Weighing the car on jack stands could be throwing off your numbers off. If you want to try to compare numbers, look over this thread on "How much does your Legend weigh".

I agree with Jim on the braided brake lines. Not best to go braided throughout. The aluminum hard lines would save you a few ounces.
Steve
-
I can't think of 50 pounds of excess stuff to take off.
I'd re-weigh it somehow...
-
If it is truly that much over here are some places to look. I am of course assuming that you bought a used car.
1. Make sure the floor pan is the correct thickness.
2. Take a flexible rod(or something) and run it down your frame tubes. It has been know that people add lead to them.
3. Tap at the bottom of the roll cage any where (especially on the left side) touches the frame rail. People have filled these with lead shot also.
These are just some of the place people with light kids add weight. They do this because they run out of room for lead the correct way. Just trying to help but I to think I would check my scales first.

They didn't happen to add any extra steel to the door area? I know nj rules dictate that they need to add steel to the left side door for safety reasons.

Aluminum brake lines are a bad idea.
Aluminum, copper and other non-ferrous metal will work harden due to vibration and crack & break.
The 3/16" steel brake lines for the complete car cannot weight more than 3-4 lbs.
You need to look elsewhere to save weight. That is a major safety issue.

Jst to add my 2 cents about brake lines..
I run braided lines throughout the whole car and have had no problems with a spongy pedal.
Thats racing on dirt though.

Yeah, I don't know, never tried it. When I approached Aeroquip to put together a whole car kit, they advised me not to....but then again, we don't use the brakes on dirt much. Anybody run full braided lines on asphalt?

I can chime in here regarding the weight issue and tell you that it IS possible to have 50lbs or more of misc weight on your car.
I have a 34 Ford Coupe that weighed 1181 race ready when I got it. (That is with 20 lbs of lead)
It now weighs 1110 race ready. (That is with 20 lbs of lead)
I removed my electric cooling fans, all my guages and misc wires, any metal shrouds in the front end, plastic ducts in the front end, a parker pumper system, all extra zip ties, wires, steel brackets etc that were there but not serving a purpose.
I switched to the lightweight aero wheels, and changed ALL my body panels. In the end I saved 71 lbs on the rebuild!
The two biggest surprises to me were the difference in weight of the body panels and how much weight removing my guages saved me.
Removing the guages and misc wires saved me a total of 9 lbs.
I dont have a total weight reduction on the body panels as I did them one piece at a time over a one year period, but I can tell you that if you have the old OLD style body like I did it is extremely heavy compared to the new stuff because there is a ton of fiberglass used and its much thicker.
My old main shell weighed 38 lbs and my new one weighs 27lbs.
It all adds up like you said but there are probably a lot of places to save weight other than brake lines.
Feel free to message me with any questions and I will gladly try and help you shed some weight if youd like.

so can anyone tell me what the thickness of the floor pan is
thanks cody
-
My coupe chassis is pretty old so this may not be current standards, but my floor pan is 1/16"

My son races in Florida we put steel braided lines on whole car brakes went out beginning of season and totaled a car since new braided lines have had no brake issues and we run all brakeman calipers pads and rotors so we are hard on brakes where mushroom hard lines into rear drum we were cracking them I think due to all the beating and banging so so far theses lines have worked and I had local gut make me up and cost 140 for all

So you are running braided brake lines currently?
