    Type RA window glass?

    I've a Classic rally car which is 30kgs over the allowed minimum weight. I haven't touched the window glass. The front screen has to stay as is. Does anyone know the thickness of the glass in the RA side windows? Does anyone have a set available to weigh / purchase?

    I don’t think there’s much difference in weight in the glass it’s the door that the weight saving is in so a full door would be lighter in an Ra compared to a standard car but James Seanie or Stephen would be better up on classics than I am

    There isn't any lighter glass in a classic. Only cars that got lighter glass were newage Spec C (open to correction!)
    Doors are the same too only thing lightweight on a RA is bonnet and boot. I assume you have manual windows?
    From rallying myself one thing i noticed loads of weight in is the heater box! Got a small heater for my civic that just blows on windscreen. Being a group N car it cant run polycarbonate windows but I assume you are class 15 or 20 so shouldnt be issue for you?

    Below is robbed from type-ra.com

    Are you running 'X bars' in your roll cage? If you are...is it permissible in the class you're in to remove the side impact bars in the OEM doors as there is huge weight in these.

    As mentioned... there is huge weight in the OEM heater system too. The below is only 1.15kg... so big saving to be had here..

    https://www.demon-tweeks.com/eu/demo...heater-tsdlwh/

    Remove as much as possible from within the dash too... unnecessary plastic trim, plastic pipework, loom etc. It all adds up. Is the sound-deadening removed?

    Next heavy thing you could look at is sub frames... I've seen some that were heavily drilled to remove weight but also seam welded for strength. If your wallet will allow... tubular sub frames could half the combined 20kg weight that the OEM ones come in at.

    If anyone weighs less than Mickey's 10 stone and can call notes PM me!

    Seriously though - the heater is something I was all set to lighten.......a single speed blowing on windscreen only. Everything else is a luxury. I don't think I need a heater matrix either.

    Thanks for sharing that information on part weights.

    I have the remains of the electric window guides in the 2 rear doors. All window motors, central locking, loom, solenoids etc are removed. I'll weigh one just to see how it compares to a 95 type RA.

    A fibreglass boot lid is only 4.5 kgs. Nearly 5 kgs of a saving on an aluminium one. You would imagine a fibreglass rear bumper would also save weight? Its actually slightly heavier than the original plastic one!

    I have a Milltek 3" system that is nearly 18 kgs but would be reluctant to remove it - the car drives too well with it. Original alloy bonnet still on the car (how it has escaped I have no idea!). Polycarbonate windows....time to text Seanie

    That garage of yours should have 'Prodrive' written over the door!

    Exhaust weight is huge I swapped a Sti genome back box for a titanium s203/204 One and there was just 4 kg weight saving in the back box alone but not a cheap option . Sherrif get a lovely titanium system recently and he might know the weight of it and cost

    Aren't all classic boot lids steel.... don't think there ever was an alloy one.

    Yeah... fibre glass bumpers are so much heavier than the plastic OEM ones.

    This US crowd are pretty cheap for tubular sub-frames... there's a 15kg saving in the front & rear ones alone not including the gearbox & T-bar mount. He does deals on the full lot too.

    You could be right on that Jamie - it makes sense weight wise.
