I needed another pair of jack stands to go along with my existing pair of Jackpoint Jackstands. I couldn't find another pair of Jackpoints but I was fortunate to find a nice deal on a pair of Rennstands which I was always curious about so I decided to try them out. I did a side by side comparison of them to highlight some of the key differences. Feel free to ask me anything you want about them.

I looked at both of those but ended up with the jack stands from Harbor Freight (ESCO copies). The welds and powder coat finish on the pair I bought are tops and I'll be getting another pair to fully lift the vehicle.

I started with Jackpoint Jackstands. Absolutely awesome - well made, study, beautifully made. I ended up with QuickJacks.

There is something very satisfying in pushing a button and watching your Porsche rise off the ground.

Nice vid and comparison, btw. From what I saw, I would never buy the Rennstands.

I also use the Quick Jacks for the versatility of heights.

Satisfying but nerve-racking.

The Quickjacks mechanically lock. The hydraulic is unloaded.

What jack points are you using on your 991 to get them on the ESCO stands?

The stands mentioned by the OP are ideal for lifting the vehicle, but I can still get the vehicle on any stand. There are a few YouTube videos on the subject.

I use jack pads, my trolley jack, car ramps (used as wheel supports) and a 1/4" x 4" x 27" (?) aluminum channel and hockey pucks under the rear suspension subframe to lift the entire rear of the vehicle. And of course these cars are so stiff, when you lift the rear jack point, the front jack point lifts moments later.

Obviously not nearly as quick as using the stands mentioned by the OP, but much cheaper. Besides, I have a Max Jax but sometimes I have another vehicle on it that cannot be removed. I need a bigger garage with a second lift.

I use the rear cross member just be careful not to lift on the oil pan. I have done this countless times, as most work is in the rear I find this is sufficient.

For certain jobs, I use wheel ramps to support the vehicle. I do not drive up on them.

Your undercarriage is cleaner than my kitchen. :-)

You should see my 993 that I bought in 2009 and it is now 29 years old. Lucked in to it and my 991. When you work on your own cars and motorcycles, working on clean vehicles is more fun.

I don't understand any of these uber expensive stand solutions (especially the QuickJack). I lift from the rear jack point high enough to add a quality jack stand under the front jackpoint, add another were the cross member meets the rail and I am done in half the time of all of these other solutions and it's as stable as any of them. 30 years -- never an issue and I only have to jack once on each side. I've seen too many friends fumble around with the QuickJack for 30 plus minutes only to get marginally higher. They do don't perform any additional maintenance then I can ... but to each his own.

It's Porsche enthusiast tradition to find $1000 solutions to $50 problems

Though I generally buy the highest quality tools possible I have 12 of my older restorations on jack stands when not in use of variable manufacturers and have never had one problem with any of them. Yes, you read correctly in that I have 48 Jack stands.
Having said that I never work on any car or tractors on Jack stands alone. I always use a second back up for safety such as railroad ties or my fork lift. I trust nothing.
