Default Subframe question 993

Well, I dont know how to put this...but I kind of made a fool out of myself.

To make a long story short when I reinstalled the engine and rear suspension I managed to assembly everything except the upper frame, see pic.





I was under a tight schedule to deliver the car as soon as possible to the body workshop.....

The question now is, can I drive it carefully to the MOT (they wont notice) and then during winter remove engine and do everything properly?
Or will the car suspension collaps without these parts installed.

You know the right answer to this, and its not just drive it.

Fix it properly

You should be commended for admitting this faux Pas in a public forum. As far as your question goes you already know the answer don't you?

Mike,
I'll offer a different opinion. If your short-term goal is to pass inspection, how about trailering the car to the MOT facility?

While the arched support is an important element of the 993 rear suspension, its absence will not cause the car to crumble to the ground in a distorted, mangled mess. Study the picture below - the large side members are bolted to the body at points #6, and subframe #2 rigidly ties these two side members together.

I certainly wouldn't drive the car like this, but rolling it around a bit will not spell disaster...

I would tend to agree with Andreas , despite the general level of outcry
simply trailering it to the MOT or even driving around your own driveway
albeit slowly should do no discernible harm...
Now on the other hand I would give any amount of money to have seen the look on your face when you realized those braces had been over looked !

That's a damn fine image you posted, Andreas! Thank you for that! Saved.

P.S. Prolly a photo of your car during an OCD cleaning episode, right?

You'll be fine rolling it around and driving it under 5-10MPH.

BTDT and feel your pain. Years ago I put an engine/trans back in my 911, hooked everything up, added oil, connected the battery, and was about to turn the key. And then noticed the ring gear sitting on top of the toolbox. Oops.

Yup, don't feel bad. It happens to everybody. Similar to Churchill, I changed the clutch on an old E30 325is and was about to replace the driveshaft when I saw the pilot bearing sitting in my parts box. At that point all you can do is laugh.....
