I had no choice on using the jack point. Good luck removing your rear subframe without using the factory jacking points.
There is no “frame rail” that far back to jack from. The rocker is all you have to work with....
I would make a cradle of wood that would spread the load across a larger part of the rocker in that case. And lift from multiple points.
But, yours is a parts car so no real damage done, no one was going to salvage those rockers for use in another car.
Both my jack points have been pushed up a bit by some previous owner, so I know I have to open up the rockers to fix what's there. And I'll add some additional reinforcement while I'm there.
Scott, I had a '67 VW convertible Beetle that had its Karmann added rocker reinforcement rusted through and I could stand on the rear bumper and rapidly shift my weight from one foot to the other and actually see the body twist. Of course you can't do much spirited driving with a 54hp engine, but your coupe has more power and torque. It has a solid roof and much more structure, but considering people have suffered cracks and failure of their differential mount you can't say that this Karmann built body was overbuilt even before corrosion weakens it.
Drive it without extensive rust repair? Ok, I'm down with that. Doing a lot of 'spirited driving'? Hmm, I'd say not recommended.
Your money, your behind. You choose.
