    For UK Sport Evos, POwer windows were an option, as was everything inc power mirrors.

    I always thought that would be a cool spec for a Sport Evo. No sunroof, no AC, no power windows, no power mirrors, a proper lightweight spec from the factory.

    I’m pretty sure the buldge/contour of the door is different. But again on a track car wouldn’t matter.

    m3 doors are different. May not make that much of a difference on a track car though. Good thought.

    Not just the glass and motors. totally gutting the doors and cutting out all the metal. Just hurts on doors that have the original VIN on them. My car is not that far gone other than sunroof tray cut out.

    The window motors alone are not heavy at all, less than 2 lbs. Didn't seem worth the lost convenience.

    Pelican has part weights on their website, very helpful in deciding what to rip out and throw away!

    I'll start a new thread on weight savings things to do. I have no idea how the heck they got them down to 2000lbs if mine is at 25xx gutted with cage? Where would several hundred pounds come from?

    When I get home in Jan I can weigh them, I never have, mainly because its two completely different schools, the Prodrive car I aim to keep as period correct as possible (and still drive it).
    The Club Racer I try to make as light as possible period lol.
    I dont know if the delta is 50lbs, I'd say the delta might be more like 25-30 lbs but to me 25-30 lbs in a race car qualifies as "alot". Now you have me wondering.
    I know when I pull the drivers door off to put the car in the trailer it requires almost no effort, when I do that with the Prodrive car I have to think about it so I dont drop it on my foot and break my toes (and the really cool cheater glass thats in it).
    The Gruppe A shells are magic.
    My silver race car is 2460 w/ me in it in impound, thats w/ gutted everything, composite fenders, hood, trunk, wing 15" wheels, 11.7" rotors, full lexan, no headlights.
    My Gruppe A car weighs about the same with full glass windows, working headlights, all steel body parts, 17" wheels and 330mm brakes.
    Those were no ordinary shells.

    My Gruppe A car has full doors with roll up windows which was to the rules of the BTCC in that period.
    My club racer doors are completely gutted.
    Huge difference.
    I have them both setup as lift offs.
    I can carry the ones for my club racer with 2 or 3 fingers
    The Gruppe A car doors require a bit more "gas" when I go to pick them up.

    One of the few things I won't remove to save weight...

    Me too. I still have power windows in my track car and love it. I've been telling myself it's pointless to swap to manual.

    Hey Ron,
    I seem to remember you (and I think Mitch Herman) did the manual window conversion when you were both running in Prepared.
    Do I also remember correctly that you told me the net savings was almost nothing that the power motors were so light that it was very little?
    Thats been a while but its always stuck with me.

    Ron always teasing us with his parts stash...lol
