Hi 914world members,
I have researched the topic of rear sway bar hitting the trunk on lowered cars on this forum (thank you all for sharing!) This is the case for my 914 - and it appears that the "easy" fix is to turn the sway bar upside down (or reverse it.) . I wanted to post pictures of my current installation to ensure that this would be the fix for me. Opinions/recommendations welcome. Also - level of effort/complexity related to the fix and anything else I should be addressing during the fix. Thank you in advance for your assistance! Cheers, Tony

Looks to me like you've got a bad bushing at one of the brackets, which will make a clunk

Thank you both! Let me take some better pictures and upload. I will also highlight the spot where it appears to be hitting. Will upload more pictures tomorrow.

Your car is too low.
The bottom collars an the Bilsteins are very high on the shock...with a spacer ?
You have aftermarket springs which look too short. And too stiff.
Unless you have these parts for a reason get stock springs, remove the spacer
and set the lower collar on the third groove (from the bottom) of the shock .
The car will be as low as necessary without the bumping.
I'm assuming they are Bilsteins by the color and the grooves but the lower collars are not familiar to me.
My suggestions apply to a lower collar as pictured.

Body mounts to the bar are NOT stock and are incorrect. Stock mount does not bolt on like that. Bar mounts hould be welded to trunk floor pan. Second the springs are not stock either, that's why they are so high.

I used the Billstein lower collars, set it on the 4th groove and it's too low, I intend to raise it to the 6th groove. Rory is using a different lower perch that effectively raises the lower height to about the 6th groove. Just a different way of getting there.

He seems to have a few issues going on.

The bar itself could be mounted upside down too.

You can mount the bar upside down on purpose which will change the angle where it connects to the drop links which in turn will prevent the bar/links from hitting the trunk floor.

I know there's picture of that setup on here somewhere ...

Take the bar off unless you are competitively driving on a racing track.

I don't want to hijack the thread, but can you tell more about this solution? I removed the bar on my 1976 V8 car for exhaust clearance reasons. It's a narrow body and will never be much of a track car (not intended to be). It's lower than stock.

Does the rear bar hurt handling or is it just that it doesn't help any?

Why did Porsche install it on the later cars? Due to the new, heavy bumpers or the taller stance?

Neither ...

I added a stock rear bar to my '70 and it makes it handle noticeably better.
