What are you doing as far as leaving in gear ( manual) or park (tiptronic) and with the handbrake?

I have seen different views on this. I have always locked everything up in gear with the brake on to avoid movement, even placking chocks to the tires.

Don't know if they are the "best" but I have a set of 4 ESCO jackstands with the flat rubber top. Very stable and no problems putting the car up on all 4 corners.

$350 will buy a set of 4 including shipping and still leave some change for gas.

BTW, Edgy01 did a good write up with pictures on the 997 forum

humm... let me define AFFORDABLE

-> $50 a pair = cheap
-> $100 a pair = >> affordable <<
-> $200 a pair = premium / toy
-> $250+ a pair = better lift the car themselves

Can't argue w/ anything said above. There are many ways to spend $299.

Just curious - how much for the damaged A/C hose repair.

More than $299. Lesson learned, believe me.

So after getting done with my clutch job I found out last night, after driving the car for less than a mile that I might have an oil leak somewhere. That means (maybe going) back up on jacks to diagnose.

I HATE putting the two front jack stands in place - especially putting 6 ton tall stands under there to get the car up at a comfortable height to drop the transmission. The side to side jacking in my small garage is hair raising.

So I'm thinking about building ramps like the ones pictured - for the front wheels only. What's a safe ramp angle to drive the car up on? I'm thinking 9 - 9.5 deg is well within safe....

I've often wondered if I had decent welding skills, why not use 4 jacks -- but make up something like a jackstand to fit under the lifting surface of the jack. So, you jack up the car, then slide in your vertical support, then lower slightly so the weight of the car is resting both on the jack and your support.

I've never used these, but I think it's the same concept you're talking about. 30 bucks each is actually pretty reasonable too. Basically jack the car enough to get the stand under at the lowest setting and then go to town, one notch on either side of the car at a time.

The attached diagram will show you the incline on commercially available Race Ramps. The auto super store ramps are shown in gray. They have a 17˚ angle which is way too steep for your car. Standard Race Ramps have a 10.7˚ constant slope. The custom Race Ramps offered by Reverse Logic have initial inclines of 4˚ to 6.8˚. The RLL-89-2 Progressive Incline ramps have a concave curved top which gets the car higher in a given distance.

9˚ may still be too steep for your car. Why not check the approach angle with the iSetSquare app available for your iPhone? Or you could just make a crude gauge from cardboard to approximate the approach angle.

I was thinking about 4 floor jacks and having a vertical support for each one (like putting a stick in an aligator's mouth). Could easily set it up to be compatible with 4 economy floor jacks.

I think the Powerbuilt Jak and stand is probably a good product, if you have 6+ inches of ground clearance for starters. Otherwise you have to prelift your car substantially. Even then these present a risk for Pcars in that you risk the factory jacking surface on your car slipping off the stand (didn't we just read about that?).

There are options for less than $299. I'd suggest something that either fits into the hole on the Porsche jacking spot or at least a high friction insulator between the two metal surfaces (jack stand and auto).
