Mark's 1G Winter Projects

I can't believe you can keep pulling more weight out of this thing, but I love it!

Yeah, the weight removal is going good. The doors and the manual brake conversion are next. I found a set of manual crank window assemblies that I purchased. I’m going to run lexan on the door glass but still have the ability to crank them down for very limited street driving, and it keeps it in street classes too. I'll hang onto the OEM glass just in case of classing restrictions too. I’ll also take out the crash beams and any anything else possible from the doors. I’ll keep track of the door project weight reduction too.

Any estimate for how much weight you have pulled out of it this winter?

The door beams weigh a bit, but not that much. It was probably about 2lbs each. The black tar paper/sound deadening stuff on the floor was more than that. Not sure if you have tackled that yet or not.

I remember Shep saying something back in the day about the power window assemblies weighing hardly anything more than the manual ones. Speedglass side windows would make a difference though.

There's a lot of inner structure around the b-pillars down where the ABS computer used to be. Not sure how much of that you can take out, but there's definitely some fat to trim there.

I was looking around and no one actually publishes the actual weight of the door bracing, but from some of the banter and judging by material thickness it looks to be north of 10 lbs each. I'll weigh them when I remove them and publish it.

Yep most of the deadening material has been removed too, I still have some left on the fire wall to remove. I exposed it after I took the HVAC box out.

They are light, but I removed the factory harness and I'm not going to power the doors for window functions. Both crank assemblies are around 3 lbs! I'll check into the ABS stuff, good recommendation!

50 ish so far? The goal is the car into the 24XX range with out me in it. Should make it faster and easier on the drive train too.

I am quite positive it wasn't anything close to that. I took mine out years ago and I remember thinking that all the work was definitely not worth it. I would guess it was about 5lbs each. The metal wasn't that thick for them. I didn't fully remove them though, just cut them off at the ends so I didn't have to drill the spot welds and possibly mess up the door skin.

Doing this saves 20lbs per door (factory glass is still in)-

Just got the passenger side door weight reduction done. I weighed the crash beam and it came to just a little over 12 lbs. I took out the electric window motor and it weighed as much as both mechanical crank setups combined. Not that they weigh a lot. I’ll post a pic as soon as photobuckets site starts working again. Drilling spot welds was easy, I just wrapped tape around a drill bit so it could not penetrate too far into the door. I used piano wire to break the adhesive bond between the crash beam and the door skin. Then an air body saw to remove the door metal and an angle grinder to cut the beam. It took around an hour and a half to get it all wrapped up. Not bad for that type of weight savings!
I also took the brake booster out, it was a little lighter than what I expected at around 8 lbs. I need to machine an adaptor bracket to fit up the other master cylinder I ordered.
So far so good!
