...I have also been looking for lightweight steering wheels, but can't find actual weights, only the word 'lightweight' which doesnt help.

What is the weight of a stock steering wheel? what do you think can be saved with an aluminum, carbon fiber, etc. steering wheel?

the weight of the stock steering wheel is the big question to see if its alot and can be lighter.


I haven't measured anything yet, but there is very noticable difference between the weight of a stock steering wheel, and something like an aftermarket MOMO wheel. The hub and frame of the stock wheel are made entirely of welded steel, and quickly adds up to a few pounds. An aftermarket MOMO wheel has a sheet aluminum frame, which is laminated with wood to form the rim. The steering hub is made of steel, but that's more than offset by the considerably lighter wheel.


I took out my stock 1993 steering wheel (rigged my own horn button) and the stuff inside was heavy. had to be like 3-5 lbs just by itself. i replaced the steering wheel with a 95+. took out all the plastic on it so it just looks like grip and metal. I am sure I could strip the metal down a bit more for a bit more weight savings but there was a lot of weight in that stock one.

It upsets me a lot. If I want to show off how "fast" my car is I have to let someone drive it alone...putting me in the passenger seat weights it down an extra 120lbs, and thats a big difference.

ROI? what does that stand for?

"it's time to start focusing on the little things to make more power."

yea, but that's a whole 'nother topic. weight reduction increases performance across the powerband, improves accel., top speed (if not limited), handling, braking, and saftey (as in maneuverability, less chance of a blowout, etc. not as in crashing), no power adder can do half of that. And the more weight you reduce, the more you power adder effectivly adds.

you're right with the body panels, it it would probably cost thousands for custom panels and make you're car a 100% certain death trap instead of just 95%.

hey i have 1994 metro 5dr us model and it weights at approx. 1750lbs stock. every part you guys listed is in my car. i want to do all of that. and then some more. to stiffen up my car with a rool cage, and lighten up even more with carbon fiber hood,hatch,doors(all 4 of them) and finders. discs brake all around. and then remove all emistions and a/c and any thing else from the motor and then yes going to the bathroom, getting a hair cut, is helpful but you all for got one thing, the most important thing. is to do it with your girlfriend or wife. having sex and releasing the extra fluid will also lighten things up a bit, PLUS not to mention it is a stress reliefer! thanks for you help, and motor on. :lol: :lol: :lol: 8)

I appreciate the value of cutting excess weight but at some point you have to decide if you want a street-worthy ride or not. If not then you need to decide if a stock or semi-stock appearance means anything to you- if not then build a tube-framed racer.

Or get into motorcycling.

Removed everything cept the dash, two front seats and the front door panels (they will go tomorrow). Swapped the 15 inch wheels for the 14's on my 89 GTI (big weight difference).

WHAT A DIFFERENCE!!!

Whet out for a test drive and kicked _ss on some Honda four door. As if he had a chance! :lol:

Sorry, didn't take the time to weight everything. From reading the weight loss forum I knew it had to help, and it did! Noticable difference. Going to look for more weight savings tomorrow. It can only help.

With all of the weight reduction my car is a lot noisier that before. You hear every pebble that gets kicked up under the car, more road and engine noise. For the past two weeks I have only driven my stripped GT. Today I drove my 99 Metro (1.6) that I used to think was noisy. Compared to the GT the Metro is a Cadillac!

GT is still 100% street worthy, just (quite) a bit noisier. I'd say worth every pound taken off of it!

Wouldn't have done it if this were my only means of transportation.

I think you'd weaken the rear suspension considerably, and I doubt you'd even save 2 pounds. :roll:

The underbody (floor pan) of our cars acts as a stressed unit because it has no frame.

Even if you install a rear strut brace (a very good Idea) you'll still need the support from the floor pan, otherwise the rear suspension will flex, making it handle like sh1t at best, and cracking the body and losing control of the car at worst.

I'm no strucural engineer, but I used to be a race suspension tech, and this is of course just my opinion. :mrgreen:

Get other opinions before you make up your mind to cut this area. :bump:

I cut it out of my MK3. I thought it was just there to hold parts of the seats and interior in place. It's really flimsy. But also really light.... :?

i got stopped twice by the cops in my 2000 metro, i have no interior other than the seats and steering wheel, no side mirrors. they both asked were my dash was and i said i was working on the car, they were ok with that. neihter cop asked about the mirrors ? one asked about no front plate because i had the empty bracket. but.....

no tickets ! both of the cops were real nice and advised me to take it easy.

i think there scared the other cops will make fun of them for busting a guy in a metro. you know, couldn't find a real car to stop.

Cleaned the car this weekend and bought some new "lightweight" floor mats haha. The mats i took out were the heavy duty rubber mats. They wieghed 11 pounds on the bathroom scale. Replaced those two mats with 4 from wal-mart and they only weighed 5.5 pounds all together. Nice little drop in weight.

Take out the under hood bracings and the trunk/hatch bracings. The door bracings are a good idea as states peviously in this thread.

Now a 'fair weather' car only...

No heater core, dash. Stripped wiring, no emissions, no wipers or wiper motor (RainX'd juuust in case).

Replaced rear hatch from a Firefly (no rear brake light or wiper...). Replaced 'power' mirrors with just a drivers non-power mirror. No door handles (not by choice, they were busted).

Need some light JDM wheels and we'll weigh this thing :)
