Very true, but again I think it depends on you use case. If you are building a track car/hot rod, it makes sense to strip the car as much as possible. But the result won't be terribly comfortable.

There is a thread somewhere on the BB with a nice list of component weights if you are thinking of doing serious weight savings. The low hanging fruit is the battery (replace with a lithium one) and spare tire, and bumpers. Much beyond that, and you start getting into modifications that impact the driving experience more fundamentally. Some mods impacting weight that I have done (and guesstimate weights):

Toss HVAC system (heat and A/C) ~50lbs
Pull all carpet and chip off sound deadening ~30lbs
Lithium battery ~20lbs
No spare/jack ~40lbs
Rota wheels ~30lbs (rotating)
Remove door cards (will eventually make some ultra light ones) ~10lbs
Remove rear parcel tray - ~5lbs
Remove lower dash panels ~5lbs
Brake booster delete and pedal box/MC replacement ~10lbs
Light weight racing seats ~20lbs
Side-pipe exhaust ~20lbs
"Big" brake kit (two piece rotors + light calipers mean lighter overall) ~5lbs
No bumpers (on track only) ~30lbs
Aluminum radiator + lightweight fans: ~5lbs
No top (convertible frame removed, hardtop used if weather demands): ~50lbs

On the to do list:
Small spring kit: ~20lbs per Alfaholics (Unsprung)
Watts Link + lightweight trailing arms: ~10lbs
Hydraulic handbrake: ~5lbs (unsprung)
Light weight clutch/flywheel: ~10lbs (rotating)
Fuel cell: ~20lbs

However, I've added in weight:
Roll bar: ~50lbs
Accusump (to do): ~10lbs
Oil cooler: ~5lbs


All in, around 300lbs off the car. That is very noticeable in the handling, but also in road manners. None of those is huge by itself, but it all adds up- yet the weight savings isn't really noticeable util you do a LOT things. It's no longer a car to take a leisurely trip to the shops in! I'd love to get it under 2,000lbs, but I think that would require more drastic measures like replacing body panels (stock should be around 2,400).

I bought one of those ford focus minis for my car.... thankfully I never had to use it... it would have not fitted over my 12.19 disk and Porsche 997 4 pot calipers...I was very lucky on that....

The Ford Mustang II also fits the 4 x 108 Alfas. "Back-in-the-day" we'd use Minilites from them, before Panasport's became available.

As to a spare:

My front tires wear out faster than the rears - mostly from camber errors on cornering. So I replace tires two at a time - F then R. When I replace the rears, I swap the spare for the best tire on hand (of the three). Be sure to swap rims too as you pretty road wheels likely don't match the spare rim. Or get a fifth rim that matches.

I don't know when is the last time you used triple A but you could be waiting 3,4,5,6 or 7 hours for something you could fix in 15 minutes.

Having a good spare has saved my tail more times than I can count. I won't drive a car without a spare, a jack I trust, and a good breaker bar with the right sockets.

Being stuck by the side of the road is lame.

Wow, that's crazy wait time. I've never waited more than 30 minutes. I was fine sitting in my car this winter while the AAA guy fought with the wheel lugs in the driving snow...

That said, I generally run with a spare. But it's nothing more than a cheap 185 on a steelie. I run with 205s which don't fit the spare well. If that weren't enough, they're directionals - I'd have to carry two...

Due to Murphy's law, you will get a flat tyre the day/week after you remove your spare

If you call AAA, or anybody, to change a tyre ... please remove your car enthusiast badge and leave it at the door as you leave!

I'll gladly hand over my badge when the wind chill dips below -35F as it did this winter when I shredded a tire on my CC...

I'd never call AAA to change a tire, but if there's no tire to change, I have no shame in calling a tow truck. For what it's worth- maybe I'm lucky, but I haven't had a flat that required a roadside change in almost 20 years. Tires have gotten pretty darn good at stopping punctures.

The spare tire is just a spare part to get you home. If have the skill or the willingness to do a road side tire change you will be on your way ASAP. If you choose to use a tow service for what ever reason that is ok too. We are all have one thing on common! We love our Alfa Romeo.

Man I don't think I'd have become a car enthusiast if I had grown up dealing with that weather ...
