No, the bolt's are on the inside of the tyre. Keeping the loaded side of the tyre to keep air. 8 to 9 psi in a kart tyre. Quote Link to comment Share on other sites More sharing options...
Daan Posted July 2, 2023 Share Posted July 2, 2023 Yes, most beadlock are single-sided, but that is usually enough. There are also traction forces to consider, which only go through one side wall in this arrangement. This can be the result: 2 Quote Link to comment Share on other sites More sharing options...

miketomcat Posted July 2, 2023 Share Posted July 2, 2023 My beadlocks are only on the outside, but I don't usually air down so they don't really do a lot. On Ladoga every time we pushed a tyre off the rim it was always the outside we did about 6 on the event and every time the inside was still on the bead. I have no reason why it's just my experience.

Bowie69 Posted July 2, 2023 Share Posted July 2, 2023 I'm sure the weight transfer has a massive amount to do with it. Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted July 2, 2023 Share Posted July 2, 2023 @Stellaghost how much road is Sid going to see? I made a track rod out of aluminium at a friends, all the ultra4 cars have them and have aluminium trailing arms and they seem to do very well with them. You can shed a whole load of weight there. I think your lightweight must be one of the only actual lightweights out there with all the alli panel work it’s just the axles. I wouldn’t be too bothered though, Sid will still be lighter than the average 90 with all the carp that never gets used bolted to it👍 1 Quote Link to comment Share on other sites More sharing options...

I would guess ultra 4 axles are a damn sight lighter than my mogs though. Lol I possibly may have the only all aluminium bodied lightweight, well until you start yours that is ...

Regards Stephen The axles may weigh more but I’m sure you won’t be launching sid like those guys do. I’ll ask him what grade when I see him, I know it’s fairly exotic as he hasto go tup north to get it and buy a certain amount in one go for the sale. you’ll be waiting a while for mine to get done, we were at billing yesterday and there was talks of putting it on a D2 chassis😂 Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted July 3, 2023 Share Posted July 3, 2023 Did I miss something, what's the sudden obsession with shaving weight? I'd think twice about how much you'd realistically save doing things like an ali tank or ali arms / steering bars, especially when it's low-down weight on stuff that might take a beating. If you're worried, leave the spare wheel with the tow car that knocks 57Kg off right away 2 Quote Link to comment Share on other sites More sharing options...

elbekko Posted July 3, 2023 Share Posted July 3, 2023 The steering bars should probably be changed out anyway? They looked to be stock LR items that were flexing quite a bit? 1 Quote Link to comment Share on other sites More sharing options...

miketomcat Posted July 3, 2023 Share Posted July 3, 2023 I agree with fridge I don't think weight saving is high priority. Unless it turns out over 2ton when you weigh it. Definitely needs more travel especially at the front but the longer springs weren't the solution standard height might help. A stronger steering bar sounds like it high on the list though.

There's ~400Kg of extra axle weight, a 200TDI vs a 2.25 petrol and all the nuke-spec stuff going on. A Lightweight is ~1500Kg IIRC, so I'll say around 2095Kg.

muddy Posted July 3, 2023 Share Posted July 3, 2023 Did you actually knock a tyre off the bead? I run 900x16 tractor tubes in basically a 750 so they don't stretch as much and wear on the ribs on the inside of a tubeless tyre, remember to talc generously when fitting them. you could always put the wheels in the lathe and knurl the bead. Fitting/losing the spare wheel could be a useful weight distribution tool. if you're not fitting it (and the tools to change it!) then chuck a tin of easy start and a lighter or two in so you can pop a tyre back on should you need to. I would sort the front steering bar, get your axle weights, chuck some cheap appropriate springs on, get that 200 wound balls out, make sure the oil and water stays in and has the appropriate warning systems working and go do some more testing/playing.

Regards Stephen Don’t you dare? I’ve referenced it 3 times today to see what I can do about my **** up😂 also, it’s very easy for people who have never seen, let alone driven sid to say what should be done. If you think he needs to go on a diet then go for it, I don’t think anyone is disagreeing with you but some may find it odd you’ve come to the conclusion so early in the build. But weight saving is fairly inexpensive and it makes what power you have go that little further. Good place to start if you feel that’s what’s needed IMO. 2 Quote Link to comment Share on other sites More sharing options...
