Air Jacks - Anyone Got Them?
Discussion
I'd like to fit Air Jacks to my E46 M3 track car as I'm planning on having three sets of wheels and it would make changing wheels a breeze...
Does anyone have experience of these? I see on the Demon Tweeks website has AP and AST versions for about £300-£350.
I suppose having them installed might cost that again if not more.
I mainly want to do it for the smug factor when my friend is there changing his wheels with his normal jack and I can just plug it in and watch it rise

By the time you mess about getting air bottles filled, carting them to track (they are big heavy bstds), rig up the hoses, deal with the inevitably leaking valves and actually get it in use your mate will have changed his wheels.
My group of track-day mates has several cars with air jacks (inc Porsche Cup, Radicals) and none of them use the jacks. A quick-lift jack and a very capable impact gun will be just as quick. Fine if you have a race-team with a mechanic there to get all the gear set up, but as a DIY effort too much grief.

Yes I'd seen there were other parts needed to go with it so would probably be a few grand.
Interesting about reliability, not much point having it done if it's going not going to last.
Maybe I should just buy a lightweight alloy jack instead.
On my previous kit car I never bothered changing the wheels as I only had one set but this time want to be set up properly for all eventualities!
Are they not fairly reliable if fitted well?
I've got a van as a tow vehicle so not worried about the gas bottle really.

Well yes it is I suppose but it's not the cost that concerns me really it's the reliability!
We have a long running "one-upmanship" contest and I'm keen to win it the next time we are both on a trackday
It would make changing wheels quite a bit easier though especially if doing it by yourself and you could quite easily have to change wheels a fair few times if it keeps raining then starting to dry then raining etc.

Not really. It takes seconds to lift the side of a car with a lightweight high-lift alloy jack. A good battery impact gun to swap the wheels, lower the car and drag the jack to the other side.The only time you are saving is positioning the jack under the jacking point and moving it from one side to the other, but you`ll be walking to the other side to swap wheels anyway.
Unless you are racing and pit-stops don`t have a minimum time there is no benefit at all. Especially on a track day !
Saying that, Air Jacks are still cool

Maybe not the greatest idea then... Oh well, saves me some money anyway!
Any recommendation for the best make of jack? Want a low/alloy one and I think the 2.5t ones go higher?

I have an SGS 'lightweight' 2.5T jack and I've been very happy with it. They only use alloy where safe (unlike most, which I wouldn't trust), so whilst they're heavier than other 'racing' jacks they will last. O.P. if you and your mates are after one-upmanship may I suggest going racing instead?..
Anyone using air jacks at a track day looks like a bit of a tool IMO. Bit like the bikers that use tyre warmers for track days. But each to their own of course!Gassing Station | Track Days | Top of Page | What's New | My Stuff
