    Default Stiffening 205gti rear suspension

    Hi all,
    I have lowered the rear of my 205 about 30mm and it drives fine until I have more than one passenger then it hits the bump stops frequently
    I have a 20mm whiteline sway bar in the back as well, but I'm after either thicker torsion bars or dampening adjustable shocks to make it stiffer.
    Where can you get thicker torsion bar? and how much?
    Are dampening adjustable shocks an option?

    Thanks in advance,
    Lewis

    You need thicker torsion bars. Speak to PeterT. I think 21mm is what you would be after. Not sure about price but 700+ is what I remember but thats not bible..
    Dampers wont do much for stiffness as such. They control the rate at which the torsion bars move if that makes sense...

    This is actually quite cheap, they are more expensive from Peugeot Sport. There is little sense in a stiffer front if you don't balance it with the rear, you will end up with a lot of "user friendly" understeer.
    The rear shocks with only control the recoil of the bars, their function is secondary to that of the torsion bar.

    The price for last years group buy was $800 per pair. A never to be repeated bargain. I suggest looking on ebay.co.uk.

    Take out the rear seats, lose the weight - if you are serious about performance.

    Don't take this the wrong way but the 700$ coilovers are probably not doing the job you suspect they should. Setting them up correctly and matching the springs rate to the rear of the car is a very sensitive and technical process. Investing in coilovers can be a good thing but needs expertise and care. This post is not designed to put you off just to make you aware so that when you do look at rear bars you can then match the front to suit.

    I tent to agree.
    If you want performance out of a little hatch, loose the passengers.

    Thanks everyone,
    I sat on the internet for a while today and found some torsion bars: http://www.shop.pug1off.com/product_...roducts_id/287
    What do you think?

    Looks the goods! I think most are running 21mm on the road here. Much more and its just too stiff for our roads.

    Then you can get the correct spring rates to match the front.

    Is the rear beam in good working order? Trailing arm shafts and bearings etc? If not, you may want to factor in the cost of that too and while your at it get some solid mounts. They make a massive difference in the feel and also the way the beam ( or the lack ) moves about when your into it..

    Yeah you wouldn't want to do a track day with 240kg of passengers, but how much do the rear seats weigh? I wouldn't have thought much more than 10kg.

    It's more about the excuse to not carry passengers.having said this, it likely starts you on the path to stripped track car or similar, like my crazy frankenstein.

    WRC teams spend well over $50,000 to reduce weight by 3 kg and they have a few hundred bhp ATW. My works car has drilled door hinges, at least three hours of work, weight savings 0.13 kg. Old track day joke "pee before you get in the car...."

    thats pretty hard core - lol

    in the bike world i've seen people spend $3k on titanium zaust systems to save 3.5kg when a couple of months at the gym would have saved 10kg

    I am not sure who you bike with, FIA rallying/racing is not a sport for posers. In this world the months in the gym have been spent, there is no 10 kg to be lost. Getting your FIA competition license involves the same fitness, stress tolerance and reaction times tests as those required of fighter pilots. I would not want to be in the same track with a guy with a heart condition or an out-of-shape dude you is tired of steering and crashes into me.

    No shaved head, there is only so much you can sacrifice for speed

    The Chinese already own all the sheep stations, too late for that.

    wow this thread's gone off topic.
    Now to bring it a little closer, how does one go about changing torsion bars?
    And has anyone ever done this to a 405 mi16? The back of my car feel a bit.... well light after stiffening the front.

    Yeah I recently bought a rebuild kit with bearing etc.. but have been too lazy to put it in.
    I emailed Pug1off.com and they said shipping will be about 60-70 pounds which i thought was fairly reasonable.
    Where ccan you get the mounts from? Worth getting?

    Thanks
