  1. That looks very nice but how are the arms coping with holes drilled all over them ?

    To my untrained eye the holes apear to be in a "non stressed" area of the arms but is this really so ?

    I had standard ones on my Range Rover and after lifting it fitted QT ones but the vibrations from the propshaft weren't very nice.

    I think it is ok this way, The idea is not new, and I went for it, having seen several rangerovers and defenders competing in the dakar rally using it and finishing. There is a logic to the diameter of the holes, in that the cross sectional area stays the same throughout the length of the arm. And as you say the centre does have very little effect on bending stress. They have seen some serious abuse for over 5 years. I havent done any stress analysis, maybe filthyboy can tell us more....

  2. Whoa, as it's a link & info from another forum & Tony is only passing on serious information that could afflict other members vehicles, why are you berating him ?

    I know Dave Marsh too & I would expect him to be straight with any of his products & any failures thereof.

    as Tony has mentioned he has contacted QT & is waiting a response.

    I consider your comment above very unfair, I'm sure you would post similar if your radius arm failed like that.

    That, and it is not the first time I see a picture of this failure on this forum. As long as these arms fail, people should know about it, because it is dangerous.

  3. Poor man's bling:

    The first time I saw the QT ones, I ran. In my humble opinion, you cant do it in the way it is done. Its too flimsy and the bottom bead is split up in pieces which are welded in places. The picture shows that it broke, yes, exactly on the weld. You can cause a lot of havoc if the other arm breaks also, which is now increasingly likely, by a factor of 2 almost.

    I made my lightweight arms from oldspec rangy arms. These are 0.5 KG lighter to begin with, and after smoking a load of holes you take out another 1 kg, making the weightsaving 1.5kg per arm. I also polished the outside of the arms with a flapwheel to reduce the tendency to crack.

    Then had it zinc plated for added bling :rolleyes:

    I personally dont bother with castor correction, although the lift is only 1-1.5 inch on my car.

  4. Check the questions for the second shogun ;)

    "Q: any rewason why the last guy who one never took it"

    "A: my mate won it wasnt selling it for that price"

    And in the end it went for lower than the first auction :lol:

    Good to see there are honest people in the world :rolleyes:

  5. In WRC they have a 2 million pound budget and 10 mechanics!

    And they usually don't throw them down a cliff face and expect to drive them afterwards!

    We are talking Heavy Challenge scene here, Different horse race.

    You telling me that the vehicles cobbled together to finish the Rain Forrest Challenge are road legal in England afterwards! :lol::lol::lol:

    NO!

    Lara

    No, they have a 20 million yearly budget and they do gravel roads at 100mph+. The mechanics are in serviceparks which they have to reach first. So, therefore the interests are much larger, therefore pressure to be competitive is much harder, but the potential to get it horribly wrong i would say 10 x higher. Still, they manage. Its a different horse race, yes, the drivers are in a much harder situation than we are.

    Yes, my vehicle was road legal when I drove home it from the docks.

    Lara, stop going round the houses over issues that have been done to death in the past.

  6. Totally agree with that.........

    I totally disagree with that. In WRC, they drive hundreds of miles in between stages with very heavy modified cars, and you retire if you dont get it to service under its own steam. That is how it should be done IMO. Its more that people cant be bothered with SVA than that people actually have good reasons for not wanting to drive on the road.

    Hell, the RFC requires 250 miles on the road, 10 days or a 750 miles hardcore offroad, then 100 miles back to the finish. And breaking down in the jungle means hitching a lift and hopefully go back later with spares to fix it. By contrast, many events in the UK, you see people retire after 1 day of competition and put it back on the trailer. Its a different attitude and you can either demand from the organizers to give in to this or you can force the competitors to act to whatever the rules say.

  7. The story of banning to sell carparts to normal people keeps popping up; If that is going to be the new rule, a lot of people will be out of a job very quickly. Think about Halfords closing the doors. The government will not be keen to that at all. I think that that is the reason why the IVA (or SVA) didnt work out as difficult as was originally proposed. If it did, a lot of kit car companies and professional body manufacturers could have closed the doors overnight.

    I think it is one of them cases were they propose something very unworkable, and after lots of arguing, something more workable is decided. Politics for you.

  8. I have 2 bits of 1 inch box section with 2 holes at the right width of the fixing holes of the roof. They clamp to the roofrails of my pug 406 estate with 2 50 mm exhaust clamps each. I also connect two straps from the roof to the car, just to be safe. The sides fit in the back, so Whenever I bash a roof to **** (it happens!), I am prepared.

  9. Interesting links from CIP, it shows diesel is more expensive before its taxed, and equal dutys come on top. In Holland, the diesel is cheaper (mainly because of the truckers), However, if you drive a car for personal use, you pay double the roadtax compared to petrol, the same for LPG. So The government is having you over either way. Something else the UK is having to contend with is the fact we are stuck on an island; You cant nip over to your neighbours to fill up cheaper. In Holland the petrol in border areas is cheaper for that reason, sponsored by the government, how bent is that?

  10. Could the same effect not be achieved by swapping the swivel housings side to side on the axle? The track rod would end up in front of the axle, the same as on a Series vehicle. The problem with reverse ackerman remains (probably true for a Series vehicle also).

    IIRC, there was a Japanese 4x4 where the drag link ball joint engaged with a socket near the end of the track rod. I'd have to do some more research to be absolutely certain though. If so, that would make a relatively simple solution to the track rod / leaf spring contact issue.

    I have looked at this option too, the problem here is that the trackrod would end up very low ( I think that was the problem), although that can be overcome with a lot off castor angle. There is also the problem of the trackrod very close to the diff cover, limiting the steering angle you will achieve. Plus the calipers are now leading rather than trailing, which is not ideal in terms of mud falling of when braking.

    All these issues are not the end of the world, but the option of lhd-rhd swivel is better IMO. It can be achieved with ordinary defender or Rangerover lhd/rhd parts, this is what I did for mine to achieve LHD on a RHD axle.

  11. I have seen this before; it is basically a lhd rh swivel and a rhd lh swivel (if that makes sense). I have seen someone using this on a series before, where there was 1 more tapered hole in both the front steering arms to take the trackrod, so the trackrod sits in front of the axle (like a series).

    There is one problem with this: your ackerman is way out of line. This means that in a corner, the outside wheel makes a sharper turn than the inside wheel, where this should be the other way round. This has not stopped people from doing it in the past, and although in theory its wrong, in practice it doesnt seem to be a problem.

    Are you planning on using the TD5 axle housing too? These swivels wont fit the series housing unfortunately.

  12. I once had a problem that looked like a blocked filter, it would run on tickover, and rev but would not run properly under load. It turned out to be a loose union on the tank, allowing a mixture of air and fuel to be pumped into the carb. Maybe?
