  1. I've been in a few vehicles with patrol Y61 axles behind an Lt230, Some have had drive train vibration on overrun badly, some haven't at all. That's more to do with unequal UJ angles (diff pinion vs t box angle) than lateral offset. That being said I'd aim for moving the diff closer to in line if possible, as its less kind on the UJ's etc We've flipped a few Y61 rear casings to give a RH drop instead of the very slightly LH drop as standard, and added trussing and full bolt on LR mounts. I'd highly recommend doing this. Get your measurements right and the original shafts fit
  2. Just scrolling through the forum and came across this. In jest I say, I think 2020 has decided for you! Here's to hoping we can all get some enjoyment out of our cars this summer!
  3. I couldn't say on that one to be honest. If you're going down the route of changing arms for handling I'd recommend considering D2 arms and watts linkage rear. I find the D2 geometry handles favourably.
  4. For what I do, the more "useless" information I can retain the better! Also if you use a lot you get to know the drill size off by heart. Ill send you some
  5. Hope this helps You've already dropped me a PM. If you just need a couple send me your address and I'll post them over. I thought of I replied here rather than on the PM it may help with others in the future who come across this thread
  6. What is the diameter of the holes now? It's worth noting that there are different types of rivnut, I believe we have at least 3 different types of M6 riv nuts at work, all with different outer diameters. I believe off the top of my head 7, 8 and 9mm od. we also have M8 riv nuts with a 10mm od if that's any help? If you need any sending over drop me a PM
  7. Sorry to hear about your bad run of luck! Glad to hear you're getting back at it. If you're after inverter MIG welders I can recommend: Kemppi in general (but with euro torch) R tech 250, Esab Rebel Thermal Arc My general rule of thumb is don't touch anything that doesn't come with a euro torch as standard. It looks like you have a decent budget from the link so you should get a lot of MIG for your money. If you wanted older proven transformer technology, I can't recommend Oxford enough. Cheers,
  8. yeah that's spot on. I'm struggling to picture what you mean.
  9. They are in fact, cleverly simple inside. each bypass tube consists of a needle/ball valve with a spring, the spring only acts as a one way valve. Its position/orientation on the body alters what effect it has and at what point on the travel of the damper. Inside, the piston /shim stacks are laid out conventionally. There really isn't much to go wrong. and they prove to be reliable in use. Internal bypass is another feature. it is effectively a bumpstop, consisting of another pair of shim stacks, (one acting as the bump stop and the other acting as a one way valve to replenish the vo
  10. That's the car. The dampers are built to spec ££££ bilstein and contain an internal bump stop system, which would replace the hydro bump as seen on U4 and some comp safari cars. Generally speaking, a normal damper or coilover does not have a specific ride height it is tuned for. Bypass dampers are a bit more complex and the position of the tubes determines a rising rate at a certain point in the travel. The reason they are used in Ultra4 is because they are much more tuneable to deal with some of the extreme terrains and the requirement of controlling the hefty weight
  11. The Bowler fast road and rally setups are very good for a bolt on solution to a standard defender - Take a look at some of the defender challenge footage. It wasn't uncommon for one or two of the drivers to keep up with/overtake scoobies on stage. Going a step up, take a look at the Bowler V6 110 Supercharged rally car. Live axle again but with some easily achievable modifications to geometry etc. - Radius arm all round, watts linkage rear, and Bilstien Coilovers. There is a video of it somewhere passing a tomcat at sweetlamb as if it was stood still! I can never find it on youtube tho
  12. Air suspension - in the form of air shocks - is used fairly regularly in off road competition. It can work pretty well. Using LR type rubber bags in competition is something I would avoid, But if it's just for fun why not give it a go - risks assessed of course. However, the complexity of the system may increase cost quicker than you might expect. I would strongly suggest looking into coilovers, or even decent (not +2" off the shelf type) coil springs, and remote reservoir dampers. regardless of spring/damper choice i would recommend hydro bumps. Drop me a PM if you want any inf
  13. No problem at all guys. Drop me an email mike@blackbirdindustries.co.uk with anything from a fag packet drawing to a ready to cut DXF and your material requirements/quantities and I'll do my best to help out.
  14. we already do a P38 conversion kit for Defender chassis. Although thats normaly a resulant requirement from engine conversions to gain space. Looking forward to seeing the finished conversion Joe!
