Default How low can you go?

I've posted this pic before. And it's the inspiration for my soon to start project. But it's a photoshop picture. Now the question is: how low can you go?

This without using air suspension. I think it all comes down to the right et values and width of the tires...

So, how low can you go, before you mess up the alignment and still have 'some' useability left? Is -6 cm the max? I'm thinking about Gaz coilovers which can do -6 max...

well if your going to park the car and not drive it then you could lower it another 20mm,

BUT if you plan to use it on regular roads,
I would suggest that the ride be restored to factory specs,
this will increase the possibity that you will not damage the engine girdle by ripping off the AC compressor the alternator or holing the oil pan.

Not to mention the tire wear from the lowered stance

If you raise up the alternator and AC compressor....you can go pretty low.

you'll bottom those out easy at -10mm in many places, and when you do, you rip off the corner of the block.


t -10mm in many places, and when you do, you rip off the corner of the block.

Here's the future.

Bought mine pretty much slammed....loved the look....got tired of scraping the front end all the time, and a couple of runs on the Tail of the Dragon was more an adventure in rubbing the front wheel wells than any sort of performance event.
Finally installed my suspension bits (Biltstein/Eibach), put the car back to minimum recommended factory specs, and went from eating tires with crappy handling to a car that even with marginal rubber goes around corners like it's on rails...
What was the question again?

Your car, your choice.

But lower than "standard" and you lose handling.

And risk your alternator and A/C compressor (which, as noted above, can tear off the front of the block). You also risk the oil pan.
If your motor mounts aren't in good shape, you really risk the oil pan.

Your front spoiler will be trashed in a week.

928 Motorsports offer skid plates (rails really) that bolt behind the spoiler, to the tow hooks that are the front LCA mounts. They do a nice job protecting the spoiler (and everything else).

But at that low, they'd be dragging almost all the time.

Edit to add:

Oops, OB car, no front spoiler. So you can't mount the skid plates. Or at least you can't hide them.

There is some wiggle room there. Hit the low side of the factory specs and it's all good.02 T

If you use skid plates as a plan B to a lowered car...

Just remember what else is gonna hit things hard..the factory plate, and that bolts to an important place. Ive seen a car with badlt bent back LCA bolts from impact there.

When I got my S4, it was lowered by about 35mm. The handling was terrible, it kept bottoming out. It was not much fun to drive. Then I had it adjusted close to factory spec. It was like driving a different car. The difference was a little bit like going from a Yugo to a Mercedes.

Hey come on, these are not the answers I wanted...

Ah well, its not that it doesnt look good without lowering. Would have been nice though. Btw this one looks a bit lower than standard. Like the stance... Like the whole car!

I've been thinking about airbagging my '84 since I've already probably gone past the point of no return with my interior modifications to resemble that of a Cayman. I've always wondered how much of the inner fenders would have to go to be able to actually achieve a fully lowered look in the rear. Would the rear have to be tubbed? Are the front fenders deep enough to accept the front wheel with the frame all the way on the ground? If you attempt this I would be very interested to see the results...

It's sitting on Koni reds and cut S4 springs. It doesn't look fully settled in the front in that photo either. The really odd thing about this car is how much smoother the ride is compared to my stock 81 with the factory sports suspension.


Here is the same car on 18's, no that is not my H2.

Its not so much that we dont LIKE you slamming it, it's that Porsche made it entirely impractical to do so in the physical layout of critical components.
