Red 9 design coilovers

  1. Has anyone got or used the red 9 design EZ RIDER COIL-OVER CONVERSION KIT – BAY WINDOW CAMPER http://www.red9design.com/type2.htm

    They seem to be a cheaper and possible safer option then getting the front beam chopped and welded.
     
  2. Cheers madpad.
     
  3. Yes can confirm very good I ran one on my bus vast improvement over crappy adjusters ride quality far better but now upgraded to twin wishbone setup and difference again is incredible and well recommended but if on a budget by far the best way to lower your bus and have a good ride quality and simon and trev at red9 very nice people go see them they have open days on one Saturday per month check website for details or give them a ring
     
  4. They work by removing the torsion springs and replacing it with coil over shock , putting most of the front weight onto to shock tower , fine if you think it's in good enough condition to take the weight
     
  5. Very true but yes I wouldn't fit to a rotten beam either I would not drive a bus with a rotten beam trev at red 9 is a structural testing engineer so he does know what he's doing lol trust the experts
     
  6. The guy selling them may well know what he's doing but once the postman has delivered said coil overs your man fitting them on his drive has no idea that he needs a rust free beam in A1 condition to bolt them on to . While on the subject ask trev next time you talk to him why on the wishbone set up he has designed it that the whole weight of the front of the bus all goes through the upside down lower ball joint leaving the top to do very litle.
     
  7. I agree should be pointed out at point of sale and as for all the weight on the bottom this is true in all twin wishbone set ups all the weight is on the wheels attached to the spindle which is attached to top wishbone you know this perfectly good enough for many high performance v8 s etc kit cars lotus design also so proven on the track etc

  9. Hi are u running ur bus on twin wishbone set up from red 9 if so how good are they ? Thinkin of putting them on mine
    Cheers stu
     
  10. I personally wouldn't touch anything which hadn't been rigorously tested and came with a full certificate of conformity. But then I work in the testing industry and see/hear every day about cases where we have conducted failure analysis across a wide range of industries where 'experts' have designed something, used it themselves and deemed it suitable for use. Our 'experts' often find them out.

    Auto manufacturers may use similar techniques, however, they will also life a vehicle in days or weeks normally on a dynamic test rig, but also in real life proving ground situations. They maintain all of this data which shows the life expectancy of a component and is also reflected in the extensive maintenance, repair, overhaul information they provide.

    Red 9 is undoubtedly nice looking kit which appears to be well made, but without that piece of paper I personally wouldn't touch it. I have personally spoken to the designers there and they are clever guys, but still, it would hold so much more sway if they could prove what they say.

    If you buy an off the shelf product made specifically for the van it will have had rigorous testing and be proven, and will be released for sale as conforming to a known standard. Its interesting that VW heritage have now released their latest lowered and narrowed beams, brandishing a TuV certificate. I'm not sure if this just applies to the manufacturing quality (as in its been made within a company which operates within a recognised quality system) or whether they have actually tested it.

    I work in an industry where we destroy things and take them way beyond the limits that they were designed to work within. For this kind of component it would only require a single structural dynamic test which could probably put a million miles on it in a matter of weeks. I may have mentioned this before but a customer of mine also manufactures alloy wheels. Their customers for high performance components (big german manufacturers) are no longer willing to accept results from 'standard' high cycle fatigue tests. This is a basic test where by the wheel is held statically in a frame by its hub and load is applied and removed to the rim in high cycle, usually 80hz+, either for a set number of cycles or until failure. The manufacturers are now requesting real time data, so they have embarked on an investment whereby they can program in a route (they will use race tracks) such as Hockenheim or Nurburgring, and the wheel will actually be tested fully and dynamically through all axis, and lifed within a matter of days.

    Then certified

    I utterly detest them. I don't think they improve anything over the original torsion beam.

    We have one in that is such a lovely bus. Sadly it has coil overs (I don't know whose set up it is so I can't say its XYZ company. The shocks are Spax). The engine is amazing. The bus lovely. The ride awful!! It's crashy and knocky. It doesn't inspire me with confidence.
