Funny you posted this today as I was going to post a picture of my Vantage on the Quickjacks today. Not only are they stable, they are far easier to position and use than jack stands with this car. I had the car on the stands for 8 hours today while I changed brake pads, cleaned calipers, repainted brake rotor hubs, etc.

I use the Quickjacks a lot with my BMW track car since it seems like I change the oil every week, transmission fluid every month, etc. and I feel perfectly safe under there. Much safer than when I used jack stands. I also take the Quickjacks to the track with me for wheel and brake pad changes.

The Quickjacks are the best DIY tool I've purchased. Two of my friends have decided to buy them since seeing mine in action.

 

I also have one and just changed my upstream O2 Sensors this week in about 1hr from start to finish and always felt very at ease. Like Jeff_335i said, it is the best investment for a DIY

 

Just chiming in to say that's a beautiful pic, Jeff!

 

Thanks! It was a great day in the garage. Tomorrow is a big British car show here so wanted it to look its best

 

Mine is on order. They said the 110V version is still unavailable so I changed my order and went with the 12V version instead. Any suggestions as to what Battery Booster to get to power it?

 

Sorry I have the 110V version...

 

I don't think it makes much difference, they told me the 12V version draws 125 amps which is much less than is needed to start a car.

This is the one I have. https://smile.amazon.com/gp/product/B000N4UQL6/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 I just picked it because I liked how the clamps have a little storage space, and that it can be left plugged in to AC power all the time (except when using it) without overcharging the internal battery. That wasn't the case with many of the less expensive boosters. It also has enough capacity to lift the car many times on a single charge so it will last a whole weekend at the track without recharging.

 

I assume this would work:

Added benefit is it's built in-tire inflator.

 

I'm pretty sure any box that can start a car will work just fine. I've senn some guys use a very small 12V motorcycle battery to run the Quickjacks.

Since you have a 911 make sure the spacing for the lifting blocks will fit your car. I posted the key dimensions earlier in this thread. Early versions of the Quickjacks didn't fit some 911 models. Although I think the latest SLX versions fit fine.

 

Joined the club and bought a Quick Jack BL-5000slx, primarily for my DB9 Volante. Three self-performed oil changes and I've paid for it!
Also, I have winter tires on wheels for my Mini Countryman, my wife's car, and two daughters' cars, so I figured that the Quick Jack would make that twice-a-year job less of a pain, too.
Did my first job using the lift today. I'd repaired the cracked washer fluid reservoir (behind the right-side front wheel well liner) on the DB9 a couple of weeks ago, but I accidentally installed the level sensor upside down. The Quick Jack certainly made getting the wheel off easy enough, but it was a bit of a pain locating the Quick Jack's rubber blocks so that they didn't cover the screws holding the liner in place. I'll probably order two sets (two front/two rear) of VelocityAP's aluminum jack pads and use them in conjunction with the Quick Jack, which I hope will help.

17-7/8" clearance at the high lock position:

 

Awesome!

I use 2 hockey pucks stacked up at each lift point, they fit inside the side skirt cutouts and don't block any screws on the bottom of my Vantage. You can get hockey pucks for about $1 a piece from Amazon.
