Are Air Jacks worth fitting on the GTR?
Discussion
Having had a look at Javier Marino`s site, linked from CJ`s site, he has fitted air jacks.
Is this a worthwhile thing to do for helping to get a real jack under there or are they just a gimmick?
I like the idea of getting them fitted, just need feedback from you guys who already have up and running cars.

Its an excellent idea to consider! I wish I'd fitted them. I don't know what the air consumption is for them, but they would be a terrific way to help get a floor jack under the car. You'll need an outside air source. Do you have an air compressor at home? Do your friends bring air compressors to the track? Here in the states a lot of guys bring air to the track (either a compressor or an 80 gallon air tank).
Falling short of that, what I did was build a set of wooden ramps that I could drive up onto. They're somewhat heavy, but I can throw them in the back of a pickup if I need to. The ramps have steps that are about 1.5". This way, you don't have to worry as much about the car rolling backwards and I have no problems hitting my front splitter. Here's a link to the plans I copied. www.mustangworld.com/ourpics/News/mwramps/index.htm

I am just looking into all things Ultima at present. Went and saw Guy Thompsons GTR at Marlow yesterday, lovely car and also met Brian, the chap building the yellow Can Am.
I just think they would make sense.
You can find out about them at www.apracing.com, no prices, but Guy says they are about £1300 and then you gotta fit them. Don`t know if it runs off the car, or as you say, from an external compressor ala Touring Cars, but if they are to be fitted, best fitted at build stage me thinks.
I will pop up to my local AP Dealer in Berks tomorrow and see what they say.
Javier has one at the front and two rears.
Will post once I hear back from him or even get him to post here if he is a member.

I use something simliar to this for the front www.raceparts-direct.com/scrpts/product.asp?typeID=17
From Demon Tweeks. Very simple and does no damage as it lays flat. Will try to find the Ap catalogue but it would be best to go to the Autosport show and ask them the price (I did). I know the the jacks are made for touring car GT racing and require external air supply. You would also need to weld brackets to the chassis to mount them. Finally you will need 4 sleeves that cover the air jacks so it is safe to work on the car.

Spoke to a Company at last years Autosport, and with a Standard 150 PSI compressor might not even lift the car, as normal working pressure was about 500-1000 PSI. If you see cars at the track with them they are using bottles filled with compressed air at 3000 PSI, to lift a car in sec's.
Easier to design a F1 Style over-centre lift bar.

HI THERE:
I will give you details by e-mail. The inboard airjacks are probably the best idea I have had for my GTR specially to work at the track and home. It is very important to ask Ultima guys to pre-fit the brackets when you ordering your chassis. They are easy to install, lightweight (2lbs each) and helps very much when tires, braking or under floor work is needed.
you can visit www.lister.co.uk for more airjacks and accessories.
Regards,
Javier

I just use a quick lift jack for my car. It only needs about 20mm of ground clearance to get under the car, and you just push on the bar, and the car lifts about a foot off the ground. Plenty high enough to do most things you want to do, or to get a jack in there to get it onto stands.
It only cost about £60, and it doesn't increase the weight of the car at all. It also doesn't require anything to be welded to the chassis
My car has a ground clearance of 55mm, so if I can manage with it, any of you road car boys should be fine with it too.

Hi!
Do you have any pictures of it?

No, but if you go to www.raceparts-direct.com and click on "Quick Lift Jack", you'll see something similar. I got mine from Demon Tweeks, and I think it was a bit cheaper than here, but it was a couple of years ago....
Quick lift jack, what a great idea!! and cheap, could have done with one of these on my Esprit.
As said in my post above, went up to my local AP stockists in Binfield, Bracknell, Berks, who are also Rally experts to see about costs for the air jacks e.t.c. and the chap there was very knowledgable, he seemed to think if not doing track days, not worth fitting and mentioned the quick lift jacks as well.
He did mention that Sachs also do a hydraulic version of the jacks, so they run fully on the car with no external attachments needed ala Range Rover for height adjustment over rough ground. His words"Bloody useless for track days if in a hurry, but great for home maintenance"
It justs needs an additional pump and reservoir. Would take around 3-5 mins to lift 400kgs, but for home maintenance or even track days if not in a hurry, could be a good idea. He is finding out about these and costs. He reckoned AP air jacks bloody expensive, at £498.94, £584.92 or £1178.64 each depending on weight and height given, ranging from 168mm, to 230mm to 310mm. As Guy says, are they worth it for a road car.
I`ve made my mind up not to get them fitted, but as Javier states, Ultima H/O will fit the brackets at build stage, as they know what is needed.

Just checked out the quick-lift jack at race.parts. It's very similar to the one I have for my Formula Continental which is about half the weight of my CanAm, and about the same weight balance. You could probably lift the front of an Ultima with that jack, but I doubt if it would last very long trying to lift the rear. The ad says it's for single seat race cars, which are in the 1000to 1200 lb. area.
