I'm building a fast road car with weight a major factor. Just looking for ideas on getting the weight down in aus wind up doors. Seen some of the uk guys cut out metal from the inside of door under the door card. Not sure How this would go in a crash. Has anyone drilled out part of the winding mechanism?m

Weight saving on aussie doors is easy in some respects, and difficult in others.
Firstly, getting rid of the door bins is the easiest and biggest chunk of weight.
Plastic window winder and door pull handles are lighter than alloy ones, do your door cards in carbon or polystyrene sheet, and for the adventerous - replace the quarter window assembly with a polycarbonate one that doesn't open.
If you want the windows to wind up and down, don't touch the mechanism - thats just asking for trouble.

The MKI sliding window doors are the lightest. Do you have Leyland doors or Deluxe/mini K wind up doors?
Cutting the inner frame out of the door will weaken it in a crash and may be illegal (I'd guess more chance of it being illegal if the car is a Leyland mini due to the ADR's).
If you just drill holes in the winding mechanism I don't see any problem with that, you can also remove the door pockets to save weight and replace the glass with perspex/"lexan glass".

For a road car?

I gave up on that years ago. I'm in the "If you want to go faster, you need more power" frame of mind. Didn't particularly want to go cutting and drilling Lillee up...

So I dynamatted my whole interior including doorcards and bonnet. Don't regret it. Now just need to work on that power bit...

Sorry back to doors

I have a GT RH door here that a PO cut and bent the crap out of the inner panel so he could get the *&^$(@ window mechanism out. Obviously he didn't know what he was doing..
Anyway now I'm going to use it in the van, maybe I'll weld all the hacked stuff back up but more likely it'll get a partial bentinnerpanelectomy.

Thanks for the ideas. I have morris k/deluxe doors, not a fan of slide window doors. I'm loving the idea of using lexan in the quarter window and making it fixed. I can't open it anyway due to my mirrors and the rubber is shot and leaking anyway. Might cut the door bins off and see how the weight is then. lexan might scratch too much over the years being wound up and down so i might keep glass in it. And Lillee I intend on working the motor for as much power as well I find it fun doing this kind of stuff anyway.

If your careful you can remove the pockets without destroying them so you can resell them or save them for replacement panels.

Are they spot welded? My guess is yes being bmc

turbo it/more boost to negate any weight differences!

perspex sliders in alloy panel-d clubby doors



they weigh less than the air around them

You should put your heart & soul into everything you do.

I'd love to but I've get enough problems from my n/a a series motor let alone adding more things to go wrong and put the whole motor under more strain haha.

are you saying the outer door skin is alloy?? or just the door trim/internal

I just saw a thread on turbocharged 998s getting useable 120bhp. So i'd reckon that could solve your problem!

My 1380 with some more tweaks and a light car should do me well. For a bit
