Title: Jacking points Post by: mangocrazy on May 06, 2016, 10:51:58 PM I've never been entirely sure what are safe jacking points on my Spider. I know that there are four 'slot' type points on the outer shell near the wheels that would take a scissor jack, but have never really trusted myself to use them. There are also some square blocks approx 50mm per side just inboard of the body skin with a hole in the middle that I'm guessing are for use with garage 4 post lifts. Is that a correct assumption?
Also, do other members have favourite jacking points for specific jobs? Title: Re: Jacking points Post by: Neil-yaj396 on May 07, 2016, 08:39:47 AM Not sure what you mean by the 'slots'? There are the two fittings for the jack in the tool kit on the Coupe. Are there four on the Spider because of the less rigid body? Either way, I wouldn't put a trolley jack under them.
The four square attachments with the hole in the middle are in fact fittings used on the production line to fit the body shell to it's overhead cradle. It's a risky business using them as jacking points, though many have over the years. The only official points for a trolley jack are the 'plates' below the rear bumper and to the front of the sub frame, but using these doesn't get the car very high. I use the sub frame near the wishbone, or to get even higher, the rear of the sub frame from behind the front wheels. At the back I use the centre fitting point for the link arms, but extreme care is needed to keep away from the link arms themselves, as these can be flimsy, and once bent even slightly your rear suspension geometry is gone.

The front crossmember moves quite a bit if you use that so I'm never 100% happy using it.

They are the jacking points that project down from the cills and are intended for use with a scissor jack. Agree about trolley jacks.The four square attachments with the hole in the middle are in fact fittings used on the production line to fit the body shell to it's overhead cradle. It's a risky business using them as jacking points, though many have over the years. Well, every day's a schoolday. I never knew that. If you were to spread the load over all four attachments to raise the car completely off the ground for stuff like exhaust repairs, would that caveat still apply?The only official points for a trolley jack are the 'plates' below the rear bumper and to the front of the sub frame, but using these doesn't get the car very high.

Yes, that mirrors my experiences. I'm aware of the fragility of the link arms. When I used the front jacking point years ago it didn't inspire me with confidence, so I've never used it since. At some point my front subframe will be coming off to be refurbished and I'm thinking of getting some plates welded on to act as jacking points. Can you see a flaw in my cunning plan? Thanks, Stuart. I've never really trusted the front crossmember either.

As above, they are often mistaken for and used as jacking points. As they were initially designed to take the weight of the car (I don't know at which point of production the car came off the cradle, was it dropped onto the engine/subframe, or was this lifted up into the shell?) in theory it should be OK. However now the cars are 30 years plus old, the danger is that these points have weakened and might collapse, or even worse get pushed up into the floor/sill! You jacking plates on the subframe theory sounds OK to me.

Matt gave some suggested axle stand points and photos in the following thread which I found a great help. Again, its a coupe in this example. http://www.betaboyz.myzen.co.uk/forum/index.php?topic=1124.0 (http://www.betaboyz.myzen.co.uk/forum/index.php?topic=1124.0) regards Graham Title: Re: Jacking points Post by: mangocrazy on May 09, 2016, 08:58:56 PM Hi Thanks Graham, that's a very useful link and gives me a few more options.Matt gave some suggested axle stand points and photos in the following thread which I found a great help.
