I have a question about jacking up a 997... This is my first 911 and I was wondering if there was a center point under the rear of the car that I can grab with my aluminum floor jack to jack the car up at the track for changing rear wheels/tires at the same time. I have seen guys grab the rear of their cars by the diff (in frnt engine cars) and I believe I have seen guys jack up older 911's from a rear center point to do both rears at the same time, but I have not seen this done on a 996/or 997. I hope this is not a stupid question... thanks

 

Should be able to change all four with only lifting the car twice by using the rear lift points. That should enable you to change each side front and rear.

 

great point, and I have done that for a complete change over. I guess I was thinking more about when I need to change out just the rears in a "worn rear situation", but fronts still ok...
Thanks for the quick response-

 

Absolutely do not lift it from beneath the engine! The jacking points are adjacent to each wheel. This is not a simple thing to do actually. If you have two jacks it goes a lot easier. Be sure, too, to buy one (or more) of the jack hole adaptor plates available from Performance Products,--keeps you from trashing the underside of the car.

 

Thanks edgy for the input. I have already obtained those pieces from P P... I was just trying to find another way to jack the rear.

Thanks

If you are changing often, do your self a favor and purchase the pins to slide the wheels on and off without screwing up the paint on your calipers. Your dealer will know the item.

 

Edgy01 - Are the jack hole adaptor plates available from Performance Products the ones labeled "993/996/Boxster Jack Pads part #911466" and cost $29.95?

If using jack stands at some point do you need two sets (4 total pads)?

 

Wheel studs would probably be an easier option; someone told me that BBS makes a nice screw-in stud-and-bolt kit for the 997. I'm still not sure why these cars come with wheel lugs.

 

GT3s are so stiff that you can get three wheels up at one time!!

 

The 997 jack plates are the same as those for the 993, 996 and Boxsters. Sorry I was unable to confirm the part number with PP,--their site isn't exactly user friendly.

The ones that work are round, have a center alignment nipple, and have a rubber piece shaped like a donut sort of, which is centered around the nipple,--which goes into a corresponding receiver in the car.

For the obcessed they could go with 4 of these (for jack stands) but I have taken pieces of 3/4 inch plywood, cut them into 4 inch squares, and place them roughly between the jacking location and the jack top. Anything that you can put between the jack and the car that is forgiving will keep the indercoat from getting damaged.

 

I have been lifting the rear of the car just behind the oil sump cover as described in this link at renntech http://www.renntech.org/forums/index.php?showtopic=3404.

What do you guys think?

 

Here's another source for jack and jack stand pads

I believe the reason they come with lug "bolts" (technically screws) instead of lug nuts is due to the preferred manufacturing process.

The studs that other cars have need to be installed through a swaging process that can potentially warp the hub by the process itself or through the residual stresses that are left after the swaging.

Tapping holes in the hubs is a better method of ensuring no warpage or residual stresses, even though it might be a little more difficult for mounting purposes.
