Rear jacking point

[Giff]

I had seen on the US sites some funky rear jacking points and seeing as I really need to start doing some work on my new Cayman I thought I'd start by knocking one up.

I made a template with cardboard and transferred it on to some 25mm square steel box section:

Did some more cutting so the nuts could be accessed and dug out some stainless nylocs and washers:

And fitted, should be able to lift the whole back end to pop the axle stands on to the jacking points.

Its drying at the moment after a couple of coats of acid etch, will post a pic of it jacked up when its finished being painted.

So far total cost £8 plus some paint and nuts I had lying around..

Hi Giff, I've seen them mentioned and bearing in mind your proposed change from 5 to 6 gearbox it'll come in useful. Since I keep up the OPC warranty but thinking of changing to a cheaper alternative, I won't do likewise since none OEM parts void Porsche Warranties but if I still did much work on my cars I'd do this. I'm sure mechanics would appreciate it.[] As for the jacking points, there are some blocks which engage into the oval holes and then can take the loads of being jacked but since they are flat with no engagement features underneath it depends on the jacks etc, I have one which I use when doing wheel changes but intend to get a spigot turned to fit my jack or the tube of the axle stands.[]

Front is a bit annoying, there has to be a way to lift the entire front end at once.

Giff, I find that lifting the car on the rear jacking point raises the front sufficient to get a stand under the front jacking point but I guess that you're aiming to raise the whole front of the car in one go. As Kevan says, you can buy aluminium jacking pads which locate in oval holes in the jacking points: http://www.ebay.co.uk/itm/151004825318?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 A bit expensive at to buy £14 per jacking point unless you have access to machining facilities to replicate and modify to fit a stand.

They look nice, I think I'll drop them a mail and see what they could do on a set of four.

I thought this was a good idea - done by a chap on RennTech:

That's a really elegant solution Richard, although I would image that you'd need a couple of very low entry trolley jacks to lift both sides evenly before inserting the stands. I struggle sometimes to locate my own low entry jack beneath the standard jacking points. Jeff

They would be easy to make with sliding rather than welded lift pads, so that when you get a newer Cayman they will be adjustable. Ok, you'd need a very low trolley jack or run it up onto low ramps. I have a pair made of old worktop two thicknesses will do it. But low level jacks aren't expensive now.[] Giff intends to do a gearbox swap, so one beam and two modified pds with using his rear jacking point should do it. Or maybe beams running lengthways?[] What does the new rear jacking point mount to Giff?

ORIGINAL: Buddy What does the new rear jacking point mount to Giff?

There is a strong ali bar that mounts to the chassis and hold the steel cover. Those jacking bars look fantastic, and I'd only need one.

A few interesting lifting methods not all of which would be first choices http://www.pelicanparts.com/techarticles/Boxster_Tech/01-BASICS-Jacking_Up/01-BASICS-Jacking_Up.htm

Worked a treat, 7.5L of Castrol's finest 5W40 slowly poured in after a good flush.

Old filter was a Mahle and the old oil was very clean which supports the service history.
