Peugeot 205 rear Suspension

Earlier this year I asked for suggestions on raising the suspension of my 1360cc 205. You guys did'nt let me down and I acted on your advice.

So far I have increased the height of the front of the car using a pair of 405 Springs. 

I have just raised the rear by adjusting the Torsion bars. However on attempting to refit the rear Shocks I found they needed to be approximately 25mm longer. It was suggested to me that 306 units would be the answer. Unfortunately looking at these they were the same length (325mm between centres).

Any ideas which shocks I could fit.

Thanks

Nigel

  1. I would have thought a spacer would be the answer either on the top or bottom of the shock absorber.

  2. ok what you need to do is cut the top (rear) end of the shocky off make a 40mm spacer and weld it all back together a second pair of shocks will help make the job easier , im not sure but you might be able to re drill the hole in the axel plates if your stuck jive me a ring 01579320473 ,ps anybody know how to get the exeter regs,regards adrian

  3. It sounds as though both of you are suggesting a similar fix, which I had not considered. Thanks for these ideas.
    Adrian, The Exeter regs can be obtained from the MCC web site www,themotorcyclingclub.org.uk Click on on 'Entry Pack'.

  4. Hi,

    I had exactly the same issue, what you will find is that your current shocks are shorter than the standard oem part, somebody has tried to lower the rear of the car. Go buy a new set, £35 from unipart and you will be sorted. Well worth the money.

    If you re-drill new holes you will need a new bolt, as I found to my peril on the Clee Hills a few years ago your car will be a virtually undriveable if you dont use very high tensile bolts. When they snap in conjunction with the torsion bar adjustments your rear end turns into a horrible bouncy nightmare!

    Good luck

  5. An alternative option is to create a spacer between the rear beam mounting points and the chassis. 25 - 40 mm as a starting point. this method means that torsion bars can remain in standard position and also damper length is unaltered. IMHO.

  6. Hi Lee,
    Thanks for suggestion, I wish my solution was as easy as this. My car had definitely not been lowered and the replacement shocks I looked at, at the scrap yard were exactly the same length.

  7. Hi Nigel,

    it looks like all the possible options have been covered here... i think to get a useful increase in clearance your choices are (in order of ease/cost)

    1. move the top mounting location of the standard shock further back (with spacers either side of the top of the shock and longer bolts)

    2. modify the shocks to make them longer

    3. make spacers to go between the beam and chassis

    or a combination of any of the above!

  8. Thats what I thought till i went and checked a new set at Unipart. there are two lenghs available, it solved my problem with the littlest amount of fuss.

  9. I guess finding an invoice with part numbers on is a tiny bit of a long shot ?

  10. Hi Lee,
    I phoned Unipart, Europarts and two other local motor factors today and none of them could provide me with a part number for a shock approximately 30mm longer. Unipart took the most time in searching, followed by Europart the others said they could not search for non standard parts.

  11. Hi,

    Are you measuring the gap before or after you load the rear torsion bar? If the car is "up in the air" without shocks the gap will be much bigger. Drop it to the ground with wheels on and standard shocks should fit. My torsion bar is fully adjusted and I have standard shocks.

    Hope that helps, other than that I can't see what else could be different.

  12. Hi Mike, Thanks for the Monroe spec sheets. Certainly some choice there. Hopefully I'll find what I need.

    Good find Mike, I got in touch with Monroe recently and was given the contact info for their technical department which may also be able to help : 012106093032 or j.ford@tenneco.co.uk

    Good luck!
