    Question Weight reduction on S3.

    Ok people, as it this Sunday is Santa Pod, I would like to reduce the weight of the beast, I read somewhere here it is a bout 1450kg and the A3 is around 1150kg even less. I have good power low down but on the speed gears i.e. 4th 5th & 6th it doesnt feel as powerful.

    I want to remove the following:
    • Spare wheel with jack etc...
    • Back seat! How much does it weigh?
    • Is it worth removing the stereo along with changer & back box?
    • Anything else would be appreciating.
    looking forward to hear your thoughts on this.

    My a3 back seats weigh 17kg, then spare wheel is around 15kg so removing them isnt going to do much really. the main thing our your big old heated seats. comfy yes but weighing in at around 40kg+ there heavy!. Remove the passenger front seat then youd get a saving of around 90kg. go further and getting bucket seats and light weight alloys you could save in total around 130kg! bringing ya hp/weight up by around 15bhp.+
    Its gone replaced with a mk2 golf gti 16v :D

    Is it easy to remove the front passenger seat? I don’t want to damage anything... and roughly how long would it take me to do it? I am not a total novice but not a mechanic either.

    I wreckon it's just a few bolts on the subframe holding the front seat down as well as a plug for the wiring. It takes me about 5mins to remove the back seats and spare wheel, the only tricky part is getting the 60/40 back rests away from the middle bracket. I think there's some kind of knack to it but I just keep wriggling until it comes off lol.

    I wouldn't waste time removing the stereo and changer either, the amount of weight you'd save would be minimal. You wouldn't even notice over a short quarter mile burst...

    The S3 is just a heavy beast unfortunately...

    Back box? Do you mean aftermarket sub woofer? leave that at home lol As for removing the passenger seat, your airbag light will come on, and you will need it reset with Vagcom or similar. Pump the tyres upto 50psi also, and take a dump before you go, that will shave a few hundrendths! lol

    i ve read that using a ligther set of alloys is beneficial, the rotational weight of a wheel is far more than say its curb weight

    IMO don't waste your time at all doing all the weight reduction, just so you have to waste your time putting it all back again. What are you going to gain 1/10th of a second? Dude, just do a few 1/4 miles and be happy with what you get, safe in the knowledge you dont have to spend hours putting it right again, and you have all the "luxury" items that makes your s3 awesome (like a spare wheel), and not just a dragster.

    You are prob better off spending the time you would have spent on weight reduction, in learning the technique required to maximise acceleration while not killing your cars components.

    Weight reduction only really comes into its own on the track where the you reap the benefits of the full dynamics of being lighter, not just acceleration, i.e. braking and cornering.

    I could not have said that any better - in total agreement with kave.

    Thank you all, I think I will just remove the back seats and the spare wheel I guess it's not worth removing the front seat as it looks long, and a friend wants to come with me. otherwise he would have no place to sit!!
